+import "filippo.io/edwards25519"
+```
+
+This library implements the edwards25519 elliptic curve, exposing the necessary APIs to build a wide array of higher-level primitives.
+Read the docs at [pkg.go.dev/filippo.io/edwards25519](https://pkg.go.dev/filippo.io/edwards25519).
+
+The code is originally derived from Adam Langley's internal implementation in the Go standard library, and includes George Tankersley's [performance improvements](https://golang.org/cl/71950). It was then further developed by Henry de Valence for use in ristretto255, and was finally [merged back into the Go standard library](https://golang.org/cl/276272) as of Go 1.17. It now tracks the upstream codebase and extends it with additional functionality.
+
+Most users don't need this package, and should instead use `crypto/ed25519` for signatures, `golang.org/x/crypto/curve25519` for Diffie-Hellman, or `github.com/gtank/ristretto255` for prime order group logic. However, for anyone currently using a fork of `crypto/internal/edwards25519`/`crypto/ed25519/internal/edwards25519` or `github.com/agl/edwards25519`, this package should be a safer, faster, and more powerful alternative.
+
+Since this package is meant to curb proliferation of edwards25519 implementations in the Go ecosystem, it welcomes requests for new APIs or reviewable performance improvements.

+## Version 1.8.1 (2024-03-26)
+
+Bugfixes:
+
+- fix race condition when context is canceled in [#1562](https://github.com/go-sql-driver/mysql/pull/1562) and [#1570](https://github.com/go-sql-driver/mysql/pull/1570)
+
+## Version 1.8.0 (2024-03-09)
+
+Major Changes:
+
+- Use `SET NAMES charset COLLATE collation`. by @methane in [#1437](https://github.com/go-sql-driver/mysql/pull/1437)
+  - Older go-mysql-driver used `collation_id` in the handshake packet. But it caused collation mismatch in some situation.
+  - If you don't specify charset nor collation, go-mysql-driver sends `SET NAMES utf8mb4` for new connection. This uses server's default collation for utf8mb4.
+  - If you specify charset, go-mysql-driver sends `SET NAMES <charset>`. This uses the server's default collation for `<charset>`.
+  - If you specify collation and/or charset, go-mysql-driver sends `SET NAMES charset COLLATE collation`.
+- PathEscape dbname in DSN. by @methane in [#1432](https://github.com/go-sql-driver/mysql/pull/1432)
+  - This is backward incompatible in rare case. Check your DSN.
+- Drop Go 1.13-17 support by @methane in [#1420](https://github.com/go-sql-driver/mysql/pull/1420)
+  - Use Go 1.18+
+- Parse numbers on text protocol too by @methane in [#1452](https://github.com/go-sql-driver/mysql/pull/1452)
+  - When text protocol is used, go-mysql-driver passed bare `[]byte` to database/sql for avoid unnecessary allocation and conversion.
+  - If user specified `*any` to `Scan()`, database/sql passed the `[]byte` into the target variable.
+  - This confused users because most user doesn't know when text/binary protocol used.
+  - go-mysql-driver 1.8 converts integer/float values into int64/double even in text protocol. This doesn't increase allocation compared to `[]byte` and conversion cost is negatable.
+- New options start using the Functional Option Pattern to avoid increasing technical debt in the Config object. Future version may introduce Functional Option for existing options, but not for now.
+  - Make TimeTruncate functional option by @methane in [1552](https://github.com/go-sql-driver/mysql/pull/1552)
+  - Add BeforeConnect callback to configuration object by @ItalyPaleAle in [#1469](https://github.com/go-sql-driver/mysql/pull/1469)
+
+
+Other changes:
+
+- Adding DeregisterDialContext to prevent memory leaks with dialers we don't need anymore by @jypelle in https://github.com/go-sql-driver/mysql/pull/1422
+- Make logger configurable per connection by @frozenbonito in https://github.com/go-sql-driver/mysql/pull/1408
+- Fix ColumnType.DatabaseTypeName for mediumint unsigned by @evanelias in https://github.com/go-sql-driver/mysql/pull/1428
+- Add connection attributes by @Daemonxiao in https://github.com/go-sql-driver/mysql/pull/1389
+- Stop `ColumnTypeScanType()` from returning `sql.RawBytes` by @methane in https://github.com/go-sql-driver/mysql/pull/1424
+- Exec() now provides access to status of multiple statements. by @mherr-google in https://github.com/go-sql-driver/mysql/pull/1309
+- Allow to change (or disable) the default driver name for registration by @dolmen in https://github.com/go-sql-driver/mysql/pull/1499
+- Add default connection attribute '_server_host' by @oblitorum in https://github.com/go-sql-driver/mysql/pull/1506
+- QueryUnescape DSN ConnectionAttribute value by @zhangyangyu in https://github.com/go-sql-driver/mysql/pull/1470
+- Add client_ed25519 authentication by @Gusted in https://github.com/go-sql-driver/mysql/pull/1518

+ - Enabled TCP Keepalives on TCP connections
+ - Optimized INFILE handling (better buffer size calculation, lazy init, ...)
+ - The DSN parser also checks for a missing separating slash
+ - Faster binary date / datetime to string formatting
+ - Also exported the MySQLWarning type
+ - mysqlConn.Close returns the first error encountered instead of ignoring all errors
+ - writePacket() automatically writes the packet size to the header
+ - readPacket() uses an iterative approach instead of the recursive approach to merge split packets
+
+New Features:
+
+ - `RegisterDial` allows the usage of a custom dial function to establish the network connection
+ - Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
+ - Logging of critical errors is configurable with `SetLogger`
+ - Google CloudSQL support
+
+Bugfixes:
+
+ - Allow more than 32 parameters in prepared statements
+ - Various old_password fixes
+ - Fixed TestConcurrent test to pass Go's race detection
+ - Fixed appendLengthEncodedInteger for large numbers
+ - Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
+
+
+## Version 1.1 (2013-11-02)
+
+Changes:
+
+  - Go-MySQL-Driver now requires Go 1.1
+  - Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
+  - Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
+  - `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
+  - DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
+  - Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
+  - Optimized the buffer for reading
+  - stmt.Query now caches column metadata
+  - New Logo
+  - Changed the copyright header to include all contributors
+  - Improved the LOAD INFILE documentation
+  - The driver struct is now exported to make the driver directly accessible
+  - Refactored the driver tests
+  - Added more benchmarks and moved all to a separate file
+  - Other small refactoring
+
+New Features:
+
+  - Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
+  - Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
+  - Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
+
+Bugfixes:
+
+  - Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
+  - Convert to DB timezone when inserting `time.Time`
+  - Split packets (more than 16MB) are now merged correctly
+  - Fixed false positive `io.EOF` errors when the data was fully read
+  - Avoid panics on reuse of closed connections
+  - Fixed empty string producing false nil values
+  - Fixed sign byte for positive TIME fields

+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the

+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be

+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License

+  * Investigate issues yourself and please send a pull request to fix it.
+
+---------------------------------------
+
+## Installation
+Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
+```bash
+go get -u github.com/go-sql-driver/mysql
+```
+Make sure [Git is installed](https://git-scm.com/downloads) on your machine and in your system's `PATH`.
+
+## Usage
+_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
+
+Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name)  as `dataSourceName`:
+
+```go
+import (
+	"database/sql"
+	"time"
+
+	_ "github.com/go-sql-driver/mysql"
+)
+
+// ...
+
+db, err := sql.Open("mysql", "user:password@/dbname")
+if err != nil {
+	panic(err)
+}
+// See "Important settings" section.
+db.SetConnMaxLifetime(time.Minute * 3)
+db.SetMaxOpenConns(10)
+db.SetMaxIdleConns(10)
+```
+
+[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
+
+### Important settings
+
+`db.SetConnMaxLifetime()` is required to ensure connections are closed by the driver safely before connection is closed by MySQL server, OS, or other middlewares. Since some middlewares close idle connections by 5 minutes, we recommend timeout shorter than 5 minutes. This setting helps load balancing and changing system variables too.
+
+`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server.
+
+`db.SetMaxIdleConns()` is recommended to be set same to `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed much more frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15.
+
+
+### DSN (Data Source Name)
+
+The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
+```
+[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
+```
+
+A DSN in its fullest form:
+```
+username:password@protocol(address)/dbname?param=value
+```
+
+Except for the databasename, all values are optional. So the minimal DSN is:
+```
+/dbname
+```
+
+If you do not want to preselect a database, leave `dbname` empty:
+```
+/
+```
+This has the same effect as an empty DSN string:
+```
+
+```
+
+`dbname` is escaped by [PathEscape()](https://pkg.go.dev/net/url#PathEscape) since v1.8.0. If your database name is `dbname/withslash`, it becomes:
+
+```
+/dbname%2Fwithslash
+```
+
+Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.

+Passwords can consist of any character. Escaping is **not** necessary.
+
+#### Protocol
+See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available.
+In general you should use a Unix domain socket if available and TCP otherwise for best performance.
+
+#### Address
+For TCP and UDP networks, addresses have the form `host[:port]`.
+If `port` is omitted, the default port will be used.
+If `host` is a literal IPv6 address, it must be enclosed in square brackets.
+The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
+
+For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
+
+#### Parameters
+*Parameters are case-sensitive!*
+
+Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
+
+##### `allowAllFiles`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowAllFiles=true` disables the file allowlist for `LOAD DATA LOCAL INFILE` and allows *all* files.
+[*Might be insecure!*](https://dev.mysql.com/doc/refman/8.0/en/load-data.html#load-data-local)
+
+##### `allowCleartextPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowCleartextPasswords=true` allows using the [cleartext client side plugin](https://dev.mysql.com/doc/en/cleartext-pluggable-authentication.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
+
+
+##### `allowFallbackToPlaintext`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowFallbackToPlaintext=true` acts like a `--ssl-mode=PREFERRED` MySQL client as described in [Command Options for Connecting to the Server](https://dev.mysql.com/doc/refman/5.7/en/connection-options.html#option_general_ssl-mode)
+
+##### `allowNativePasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        true
+```
+`allowNativePasswords=false` disallows the usage of MySQL native password method.
+
+##### `allowOldPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
+
+##### `charset`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset fails. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
+
+See also [Unicode Support](#unicode-support).
+
+##### `checkConnLiveness`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        true
+```
+
+On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection.
+`checkConnLiveness=false` disables this liveness check of connections.
+
+##### `collation`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        utf8mb4_general_ci
+```
+
+Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
+
+A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
+
+The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5.  You should use an older collation (e.g. `utf8_general_ci`) for older MySQL.
+
+Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).
+
+See also [Unicode Support](#unicode-support).
+
+##### `clientFoundRows`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
+
+##### `columnsWithAlias`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
+
+```
+SELECT u.id FROM users as u
+```
+
+will return `u.id` instead of just `id` if `columnsWithAlias=true`.
+
+##### `interpolateParams`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
+
+*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are rejected as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
+
+##### `loc`
+
+```
+Type:           string
+Valid Values:   <escaped name>
+Default:        UTC
+```
+
+Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
+
+Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
+
+Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
+
+##### `timeTruncate`
+
+```
+Type:           duration
+Default:        0
+```
+
+[Truncate time values](https://pkg.go.dev/time#Duration.Truncate) to the specified duration. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+##### `maxAllowedPacket`
+```
+Type:          decimal number
+Default:       64*1024*1024
+```
+
+Max packet size allowed in bytes. The default value is 64 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
+
+##### `multiStatements`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+Allow multiple statements in one query. This can be used to bach multiple queries. Use [Rows.NextResultSet()](https://pkg.go.dev/database/sql#Rows.NextResultSet) to get result of the second and subsequent queries.
+
+When `multiStatements` is used, `?` parameters must only be used in the first statement. [interpolateParams](#interpolateparams) can be used to avoid this limitation unless prepared statement is used explicitly.
+
+It's possible to access the last inserted ID and number of affected rows for multiple statements by using `sql.Conn.Raw()` and the `mysql.Result`. For example:
+
+```go
+conn, _ := db.Conn(ctx)
+conn.Raw(func(conn any) error {
+  ex := conn.(driver.Execer)
+  res, err := ex.Exec(`
+  UPDATE point SET x = 1 WHERE y = 2;
+  UPDATE point SET x = 2 WHERE y = 3;
+  `, nil)
+  // Both slices have 2 elements.
+  log.Print(res.(mysql.Result).AllRowsAffected())
+  log.Print(res.(mysql.Result).AllLastInsertIds())
+})
+```
+
+##### `parseTime`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
+The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
+
+
+##### `readTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+##### `rejectReadOnly`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+
+`rejectReadOnly=true` causes the driver to reject read-only connections. This
+is for a possible race condition during an automatic failover, where the mysql
+client gets connected to a read-only replica after the failover.
+
+Note that this should be a fairly rare case, as an automatic failover normally
+happens when the primary is down, and the race condition shouldn't happen
+unless it comes back up online as soon as the failover is kicked off. On the
+other hand, when this happens, a MySQL application can get stuck on a
+read-only connection until restarted. It is however fairly easy to reproduce,
+for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
+
+If you are not relying on read-only transactions to reject writes that aren't
+supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
+is safer for failovers.
+
+Note that ERROR 1290 can be returned for a `read-only` server and this option will
+cause a retry for that error. However the same error number is used for some
+other cases. You should ensure your application will never cause an ERROR 1290
+except for `read-only` mode when enabling this option.
+
+
+##### `serverPubKey`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
+Public keys are used to transmit encrypted data, e.g. for authentication.
+If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
+
+
+##### `timeout`
+
+```
+Type:           duration
+Default:        OS default
+```
+
+Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+
+##### `tls`
+
+```
+Type:           bool / string
+Valid Values:   true, false, skip-verify, preferred, <name>
+Default:        false
+```
+
+`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security. You can use a custom TLS config after registering it with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
+
+
+##### `writeTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+##### `connectionAttributes`
+
+```
+Type:           comma-delimited string of user-defined "key:value" pairs
+Valid Values:   (<name1>:<value1>,<name2>:<value2>,...)
+Default:        none
+```
+
+[Connection attributes](https://dev.mysql.com/doc/refman/8.0/en/performance-schema-connection-attribute-tables.html) are key-value pairs that application programs can pass to the server at connect time.
+
+##### System Variables
+
+Any other parameters are interpreted as system variables:
+  * `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
+  * `<enum_var>=<value>`: `SET <enum_var>=<value>`
+  * `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
+
+Rules:
+* The values for string variables must be quoted with `'`.
+* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
+ (which implies values of string variables must be wrapped with `%27`).
+
+Examples:
+  * `autocommit=1`: `SET autocommit=1`
+  * [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
+  * [`transaction_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_transaction_isolation): `SET transaction_isolation='REPEATABLE-READ'`
+
+
+#### Examples
+```
+user@unix(/path/to/socket)/dbname
+```
+
+```
+root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
+```
+
+```
+user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
+```
+
+Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
+```
+user:password@/dbname?sql_mode=TRADITIONAL
+```
+
+TCP via IPv6:
+```
+user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
+```
+
+TCP on a remote host, e.g. Amazon RDS:
+```
+id:password@tcp(your-amazonaws-uri.com:3306)/dbname
+```
+
+Google Cloud SQL on App Engine:
+```
+user:password@unix(/cloudsql/project-id:region-name:instance-name)/dbname
+```
+
+TCP using default port (3306) on localhost:
+```
+user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
+```
+
+Use the default protocol (tcp) and host (localhost:3306):
+```
+user:password@/dbname
+```
+
+No Database preselected:
+```
+user:password@/
+```
+
+
+### Connection pool and timeouts
+The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
+
+## `ColumnType` Support
+This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported. All Unsigned database type names will be returned `UNSIGNED ` with `INT`, `TINYINT`, `SMALLINT`, `MEDIUMINT`, `BIGINT`.
+
+## `context.Context` Support
+Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
+See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
+
+
+### `LOAD DATA LOCAL INFILE` support
+For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
+```go
+import "github.com/go-sql-driver/mysql"
+```
+
+Files must be explicitly allowed by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the allowlist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](https://dev.mysql.com/doc/refman/8.0/en/load-data.html#load-data-local)).
+
+To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
+
+See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
+
+
+### `time.Time` support
+The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
+
+However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical equivalent in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
+
+**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
+
+
+### Unicode support
+Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
+
+Other charsets / collations can be set using the [`charset`](#charset) or [`collation`](#collation) DSN parameter.
+
+- When only the `charset` is specified, the `SET NAMES <charset>` query is sent and the server's default collation is used.
+- When both the `charset` and `collation` are specified, the `SET NAMES <charset> COLLATE <collation>` query is sent.
+- When only the `collation` is specified, the collation is specified in the protocol handshake and the `SET NAMES` query is not sent. This can save one roundtrip, but note that the server may ignore the specified collation silently and use the server's default charset/collation instead.
+
+See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
+
+## Testing / Development
+To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
+
+Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.

+# Installation
+
+This package can be installed with the `go get` command:
+
+    go get github.com/mattn/go-sqlite3
+
+_go-sqlite3_ is *cgo* package.
+If you want to build your app using go-sqlite3, you need gcc.
+However, after you have built and installed _go-sqlite3_ with `go install github.com/mattn/go-sqlite3` (which requires gcc), you can build your app without relying on gcc in future.
+
+***Important: because this is a `CGO` enabled package, you are required to set the environment variable `CGO_ENABLED=1` and have a `gcc` compiler present within your path.***
+
+# API Reference
+
+API documentation can be found [here](http://godoc.org/github.com/mattn/go-sqlite3).
+
+Examples can be found under the [examples](./_example) directory.
+
+# Connection String
+
+When creating a new SQLite database or connection to an existing one, with the file name additional options can be given.
+This is also known as a DSN (Data Source Name) string.
+
+Options are append after the filename of the SQLite database.
+The database filename and options are separated by an `?` (Question Mark).
+Options should be URL-encoded (see [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)).
+
+This also applies when using an in-memory database instead of a file.
+
+Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
+
+This library supports DSN options of SQLite itself and provides additional options.
+
+Boolean values can be one of:
+* `0` `no` `false` `off`
+* `1` `yes` `true` `on`

+
+# Features
+
+This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build `tags`.
+
+Click [here](https://golang.org/pkg/go/build/#hdr-Build_Constraints) for more information about build tags / constraints.
+
+### Usage
+
+If you wish to build this library with additional extensions / features, use the following command:
+
+```bash
+go build -tags "<FEATURE>"
+```
+
+For available features, see the extension list.
+When using multiple build tags, all the different tags should be space delimited.
+
+Example:
+
+```bash
+go build -tags "icu json1 fts5 secure_delete"
+```
+
+### Feature / Extension List
+
+| Extension | Build Tag | Description |
+|-----------|-----------|-------------|
+| Additional Statistics | sqlite_stat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.<br><br>The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |
+| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or "localhost".<br><br>However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way |
+| App Armor | sqlite_app_armor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. <br><br>App Armor is not available under `Windows`. |
+| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.<br><br>To disable extension loading add the build tag `sqlite_omit_load_extension`. |
+| Enable Serialization with `libsqlite3` | sqlite_serialize | Serialization and deserialization of a SQLite database is available by default, unless the build tag `libsqlite3` is set.<br><br>To enable this functionality even if `libsqlite3` is set, add the build tag `sqlite_serialize`. |
+| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.<br><br>Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.<br><br>Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default | 
+| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |
+| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |
+| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |
+|  International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build |
+| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. <ul><li>PRAGMA function_list</li><li>PRAGMA module_list</li><li>PRAGMA pragma_list</li></ul> |
+| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |
+| Math Functions | sqlite_math_functions | This compile-time option enables built-in scalar math functions. For more information see [Built-In Mathematical SQL Functions](https://www.sqlite.org/lang_mathfunc.html) |
+| OS Trace | sqlite_os_trace | This option enables OSTRACE() debug logging. This can be verbose and should not be used in production. |
+| Pre Update Hook | sqlite_preupdate_hook | Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table. |
+| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.<br><br>When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.<br><br>The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.<br><br>On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information |
+| Secure Delete (FAST) | sqlite_secure_delete_fast | For more information see [PRAGMA secure_delete](https://www.sqlite.org/pragma.html#pragma_secure_delete) |
+| Tracing / Debug | sqlite_trace | Activate trace functions |
+| User Authentication | sqlite_userauth | SQLite User Authentication see [User Authentication](#user-authentication) for more information. |
+| Virtual Tables | sqlite_vtable | SQLite Virtual Tables see [SQLite Official VTABLE Documentation](https://www.sqlite.org/vtab.html) for more information, and a [full example here](https://github.com/mattn/go-sqlite3/tree/master/_example/vtable) |
+
+# Compilation
+
+This package requires the `CGO_ENABLED=1` environment variable if not set by default, and the presence of the `gcc` compiler.
+
+If you need to add additional CFLAGS or LDFLAGS to the build command, and do not want to modify this package, then this can be achieved by using the `CGO_CFLAGS` and `CGO_LDFLAGS` environment variables.
+
+## Android
+
+This package can be compiled for android.
+Compile with:
+
+```bash
+go build -tags "android"
+```
+
+For more information see [#201](https://github.com/mattn/go-sqlite3/issues/201)
+
+# ARM
+
+To compile for `ARM` use the following environment:
+
+```bash
+env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
+    CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
+    go build -v 
+```
+
+Additional information:
+- [#242](https://github.com/mattn/go-sqlite3/issues/242)
+- [#504](https://github.com/mattn/go-sqlite3/issues/504)
+
+# Cross Compile
+
+This library can be cross-compiled.
+
+In some cases you are required to the `CC` environment variable with the cross compiler.
+
+## Cross Compiling from macOS
+The simplest way to cross compile from macOS is to use [xgo](https://github.com/karalabe/xgo).
+
+Steps:
+- Install [musl-cross](https://github.com/FiloSottile/homebrew-musl-cross) (`brew install FiloSottile/musl-cross/musl-cross`).
+- Run `CC=x86_64-linux-musl-gcc CXX=x86_64-linux-musl-g++ GOARCH=amd64 GOOS=linux CGO_ENABLED=1 go build -ldflags "-linkmode external -extldflags -static"`.
+
+Please refer to the project's [README](https://github.com/FiloSottile/homebrew-musl-cross#readme) for further information.
+
+# Google Cloud Platform
+
+Building on GCP is not possible because Google Cloud Platform does not allow `gcc` to be executed.
+
+Please work only with compiled final binaries.
+
+## Linux
+
+To compile this package on Linux, you must install the development tools for your linux distribution.
+
+To compile under linux use the build tag `linux`.
+
+```bash
+go build -tags "linux"
+```
+
+If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
+
+```
+go build -tags "libsqlite3 linux"
+```
+
+### Alpine
+
+When building in an `alpine` container  run the following command before building:
+
+```
+apk add --update gcc musl-dev
+```
+
+### Fedora
+
+```bash
+sudo yum groupinstall "Development Tools" "Development Libraries"
+```
+
+### Ubuntu
+
+```bash
+sudo apt-get install build-essential
+```
+
+## macOS
+
+macOS should have all the tools present to compile this package. If not, install XCode to add all the developers tools.
+
+Required dependency:
+
+```bash
+brew install sqlite3
+```
+
+For macOS, there is an additional package to install which is required if you wish to build the `icu` extension.
+
+This additional package can be installed with `homebrew`:
+
+```bash
+brew upgrade icu4c
+```
+
+To compile for macOS on x86:
+
+```bash
+go build -tags "darwin amd64"
+```
+
+To compile for macOS on ARM chips:
+
+```bash
+go build -tags "darwin arm64"
+```
+
+If you wish to link directly to libsqlite3, use the `libsqlite3` build tag:
+
+```
+# x86 
+go build -tags "libsqlite3 darwin amd64"
+# ARM
+go build -tags "libsqlite3 darwin arm64"
+```

+
+## Windows
+
+To compile this package on Windows, you must have the `gcc` compiler installed.
+
+1) Install a Windows `gcc` toolchain.
+2) Add the `bin` folder to the Windows path, if the installer did not do this by default.
+3) Open a terminal for the TDM-GCC toolchain, which can be found in the Windows Start menu.
+4) Navigate to your project folder and run the `go build ...` command for this package.
+
+For example the TDM-GCC Toolchain can be found [here](https://jmeubank.github.io/tdm-gcc/).
+
+## Errors
+
+- Compile error: `can not be used when making a shared object; recompile with -fPIC`
+
+    When receiving a compile time error referencing recompile with `-FPIC` then you
+    are probably using a hardend system.
+
+    You can compile the library on a hardend system with the following command.
+
+    ```bash
+    go build -ldflags '-extldflags=-fno-PIC'
+    ```
+
+    More details see [#120](https://github.com/mattn/go-sqlite3/issues/120)
+
+- Can't build go-sqlite3 on windows 64bit.
+
+    > Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
+    > See: [#27](https://github.com/mattn/go-sqlite3/issues/27)
+
+- `go get github.com/mattn/go-sqlite3` throws compilation error.
+
+    `gcc` throws: `internal compiler error`

+
+# User Authentication
+
+This package supports the SQLite User Authentication module.
+
+## Compile
+
+To use the User authentication module, the package has to be compiled with the tag `sqlite_userauth`. See [Features](#features).
+
+## Usage
+
+### Create protected database
+
+To create a database protected by user authentication, provide the following argument to the connection string `_auth`.
+This will enable user authentication within the database. This option however requires two additional arguments:
+
+- `_auth_user`
+- `_auth_pass`
+
+When `_auth` is present in the connection string user authentication will be enabled and the provided user will be created
+as an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.
+
+Example connection strings:
+
+Create an user authentication database with user `admin` and password `admin`:
+
+`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin`
+
+Create an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding:
+
+`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1`
+
+### Password Encoding
+
+The passwords within the user authentication module of SQLite are encoded with the SQLite function `sqlite_cryp`.
+This function uses a ceasar-cypher which is quite insecure.
+This library provides several additional password encoders which can be configured through the connection string.
+
+The password cypher can be configured with the key `_auth_crypt`. And if the configured password encoder also requires an
+salt this can be configured with `_auth_salt`.
+
+#### Available Encoders
+
+- SHA1
+- SSHA1 (Salted SHA1)
+- SHA256
+- SSHA256 (salted SHA256)
+- SHA384
+- SSHA384 (salted SHA384)
+- SHA512
+- SSHA512 (salted SHA512)
+
+### Restrictions
+
+Operations on the database regarding user management can only be preformed by an administrator user.
+
+### Support
+
+The user authentication supports two kinds of users:
+
+- administrators
+- regular users
+
+### User Management
+
+User management can be done by directly using the `*SQLiteConn` or by SQL.
+
+#### SQL
+
+The following sql functions are available for user management:
+
+| Function | Arguments | Description |
+|----------|-----------|-------------|
+| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |
+| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.<br>if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |
+| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |
+| `authUserDelete` | username `string` | Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |
+
+These functions will return an integer:
+
+- 0 (SQLITE_OK)
+- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges
+
+##### Examples
+
+```sql
+// Autheticate user
+// Create Admin User
+SELECT auth_user_add('admin2', 'admin2', 1);
+
+// Change password for user
+SELECT auth_user_change('user', 'userpassword', 0);
+
+// Delete user
+SELECT user_delete('user');
+```
+
+#### *SQLiteConn
+
+The following functions are available for User authentication from the `*SQLiteConn`:
+
+| Function | Description |
+|----------|-------------|
+| `Authenticate(username, password string) error` | Authenticate user |
+| `AuthUserAdd(username, password string, admin bool) error` | Add user |
+| `AuthUserChange(username, password string, admin bool) error` | Modify user |
+| `AuthUserDelete(username string) error` | Delete user |
+
+### Attached database
+
+When using attached databases, SQLite will use the authentication from the `main` database for the attached database(s).
+
+# Extensions
+
+If you want your own extension to be listed here, or you want to add a reference to an extension; please submit an Issue for this.
+
+## Spatialite
+
+Spatialite is available as an extension to SQLite, and can be used in combination with this repository.
+For an example, see [shaxbee/go-spatialite](https://github.com/shaxbee/go-spatialite).
+
+## extension-functions.c from SQLite3 Contrib
+
+extension-functions.c is available as an extension to SQLite, and provides the following functions:
+
+- Math: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, log, log10, power, sign, sqrt, square, ceil, floor, pi.
+- String: replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim, replace, reverse, proper, padl, padr, padc, strfilter.
+- Aggregate: stdev, variance, mode, median, lower_quartile, upper_quartile
+
+For an example, see [dinedal/go-sqlite3-extension-functions](https://github.com/dinedal/go-sqlite3-extension-functions).
+
+# FAQ
+
+- Getting insert error while query is opened.
+
+    > You can pass some arguments into the connection string, for example, a URI.
+    > See: [#39](https://github.com/mattn/go-sqlite3/issues/39)
+
+- Do you want to cross compile? mingw on Linux or Mac?
+
+    > See: [#106](https://github.com/mattn/go-sqlite3/issues/106)
+    > See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
+
+- Want to get time.Time with current locale
+
+    Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.
+
+- Can I use this in multiple routines concurrently?
+
+    Yes for readonly. But not for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).
+
+- Why I'm getting `no such table` error?
+
+    Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
+
+    Each connection to `":memory:"` opens a brand new in-memory sql database, so if
+    the stdlib's sql engine happens to open another connection and you've only
+    specified `":memory:"`, that connection will see a brand new database. A
+    workaround is to use `"file::memory:?cache=shared"` (or `"file:foobar?mode=memory&cache=shared"`). Every
+    connection to this string will point to the same in-memory database.
+    
+    Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the [max idle connection limit](https://golang.org/pkg/database/sql/#DB.SetMaxIdleConns) is > 0, and the [connection lifetime](https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime) is infinite.
+

+
+- Reading from database with large amount of goroutines fails on OSX.
+
+    OS X limits OS-wide to not have more than 1000 files open simultaneously by default.
+
+    For more information, see [#289](https://github.com/mattn/go-sqlite3/issues/289)
+
+- Trying to execute a `.` (dot) command throws an error.
+
+    Error: `Error: near ".": syntax error`
+    Dot command are part of SQLite3 CLI, not of this library.
+
+    You need to implement the feature or call the sqlite3 cli.
+
+    More information see [#305](https://github.com/mattn/go-sqlite3/issues/305).
+
+- Error: `database is locked`
+
+    When you get a database is locked, please use the following options.
+
+    Add to DSN: `cache=shared`
+
+    Example:
+    ```go
+    db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
+    ```
+
+    Next, please set the database connections of the SQL package to 1:
+    
+    ```go
+    db.SetMaxOpenConns(1)
+    ```
+
+    For more information, see [#209](https://github.com/mattn/go-sqlite3/issues/209).

+# Supported Types
+
+Currently, go-sqlite3 supports the following data types.
+
+	+------------------------------+
+	|go        | sqlite3           |
+	|----------|-------------------|
+	|nil       | null              |
+	|int       | integer           |
+	|int64     | integer           |
+	|float64   | float             |
+	|bool      | integer           |
+	|[]byte    | blob              |
+	|string    | text              |
+	|time.Time | timestamp/datetime|
+	+------------------------------+
+
+# SQLite3 Extension
+
+You can write your own extension module for sqlite3. For example, below is an
+extension for a Regexp matcher operation.
+
+	#include <pcre.h>
+	#include <string.h>
+	#include <stdio.h>
+	#include <sqlite3ext.h>
+
+	SQLITE_EXTENSION_INIT1
+	static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
+	  if (argc >= 2) {
+	    const char *target  = (const char *)sqlite3_value_text(argv[1]);
+	    const char *pattern = (const char *)sqlite3_value_text(argv[0]);
+	    const char* errstr = NULL;
+	    int erroff = 0;
+	    int vec[500];
+	    int n, rc;
+	    pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
+	    rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
+	    if (rc <= 0) {
+	      sqlite3_result_error(context, errstr, 0);
+	      return;
+	    }
+	    sqlite3_result_int(context, 1);
+	  }
+	}
+
+	#ifdef _WIN32
+	__declspec(dllexport)
+	#endif
+	int sqlite3_extension_init(sqlite3 *db, char **errmsg,
+	      const sqlite3_api_routines *api) {
+	  SQLITE_EXTENSION_INIT2(api);
+	  return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
+	      (void*)db, regexp_func, NULL, NULL);
+	}
+
+It needs to be built as a so/dll shared library. And you need to register
+the extension module like below.
+
+	sql.Register("sqlite3_with_extensions",
+		&sqlite3.SQLiteDriver{
+			Extensions: []string{
+				"sqlite3_mod_regexp",
+			},
+		})
+
+Then, you can use this extension.
+
+	rows, err := db.Query("select text from mytable where name regexp '^golang'")
+
+# Connection Hook
+
+You can hook and inject your code when the connection is established by setting
+ConnectHook to get the SQLiteConn.
+
+	sql.Register("sqlite3_with_hook_example",
+			&sqlite3.SQLiteDriver{
+					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
+						sqlite3conn = append(sqlite3conn, conn)
+						return nil
+					},
+			})
+
+You can also use database/sql.Conn.Raw (Go >= 1.13):
+
+	conn, err := db.Conn(context.Background())
+	// if err != nil { ... }
+	defer conn.Close()
+	err = conn.Raw(func (driverConn any) error {
+		sqliteConn := driverConn.(*sqlite3.SQLiteConn)
+		// ... use sqliteConn
+	})
+	// if err != nil { ... }
+
+# Go SQlite3 Extensions
+
+If you want to register Go functions as SQLite extension functions
+you can make a custom driver by calling RegisterFunction from
+ConnectHook.
+
+	regex = func(re, s string) (bool, error) {
+		return regexp.MatchString(re, s)
+	}
+	sql.Register("sqlite3_extended",
+			&sqlite3.SQLiteDriver{
+					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
+						return conn.RegisterFunc("regexp", regex, true)
+					},
+			})
+
+You can then use the custom driver by passing its name to sql.Open.
+
+	var i int
+	conn, err := sql.Open("sqlite3_extended", "./foo.db")
+	if err != nil {
+		panic(err)
+	}
+	err = db.QueryRow(`SELECT regexp("foo.*", "seafood")`).Scan(&i)
+	if err != nil {
+		panic(err)
+	}
+
+See the documentation of RegisterFunc for more details.

+// This function is uses a caesar-cypher by default
+// and is used within the UserAuthentication module to encode
+// the password.
+//
+// The provided functions can be used as an overload to the sqlite_crypt
+// function through the use of the RegisterFunc on the connection.
+//
+// Because the functions can serv a purpose to an end-user
+// without using the UserAuthentication module
+// the functions are default compiled in.
+//
+// From SQLITE3 - user-auth.txt
+// The sqlite_user.pw field is encoded by a built-in SQL function
+// "sqlite_crypt(X,Y)".  The two arguments are both BLOBs.  The first argument
+// is the plaintext password supplied to the sqlite3_user_authenticate()
+// interface.  The second argument is the sqlite_user.pw value and is supplied
+// so that the function can extract the "salt" used by the password encoder.
+// The result of sqlite_crypt(X,Y) is another blob which is the value that
+// ends up being stored in sqlite_user.pw.  To verify credentials X supplied
+// by the sqlite3_user_authenticate() routine, SQLite runs:
+//
+//     sqlite_user.pw == sqlite_crypt(X, sqlite_user.pw)
+//
+// To compute an appropriate sqlite_user.pw value from a new or modified
+// password X, sqlite_crypt(X,NULL) is run.  A new random salt is selected
+// when the second argument is NULL.
+//
+// The built-in version of of sqlite_crypt() uses a simple Caesar-cypher
+// which prevents passwords from being revealed by searching the raw database
+// for ASCII text, but is otherwise trivally broken.  For better password
+// security, the database should be encrypted using the SQLite Encryption
+// Extension or similar technology.  Or, the application can use the
