# filippo.io/edwards25519
```
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.

# Changelog
## v1.9.3 (2025-06-13)
* `tx.Commit()` and `tx.Rollback()` returned `ErrInvalidConn` always.
Now they return cached real error if present. (#1690)
* Optimize reading small resultsets to fix performance regression
introduced by compression protocol support. (#1707)
* Fix `db.Ping()` on compressed connection. (#1723)
## v1.9.2 (2025-04-07)
v1.9.2 is a re-release of v1.9.1 due to a release process issue; no changes were made to the content.
## v1.9.1 (2025-03-21)
### Major Changes
* Add Charset() option. (#1679)
### Bugfixes
* go.mod: fix go version format (#1682)
* Fix FormatDSN missing ConnectionAttributes (#1619)
## v1.9.0 (2025-02-18)
### Major Changes
- Implement zlib compression. (#1487)
- Supported Go version is updated to Go 1.21+. (#1639)
- Add support for VECTOR type introduced in MySQL 9.0. (#1609)
- Config object can have custom dial function. (#1527)
### Bugfixes
- Fix auth errors when username/password are too long. (#1625)
- Check if MySQL supports CLIENT_CONNECT_ATTRS before sending client attributes. (#1640)
- Fix auth switch request handling. (#1666)
### Other changes
- Add "filename:line" prefix to log in go-mysql. Custom loggers now show it. (#1589)
- Improve error handling. It reduces the "busy buffer" errors. (#1595, #1601, #1641)
- Use `strconv.Atoi` to parse max_allowed_packet. (#1661)
- `rejectReadOnly` option now handles ER_READ_ONLY_MODE (1290) error too. (#1660)
## 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
## Version 1.7.1 (2023-04-25)
Changes:
- bump actions/checkout@v3 and actions/setup-go@v3 (#1375)
- Add go1.20 and mariadb10.11 to the testing matrix (#1403)
- Increase default maxAllowedPacket size. (#1411)

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`, `BIGINT`.

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.
> [!IMPORTANT]
> The `QueryContext`, `ExecContext`, etc. variants provided by `database/sql` will cause the connection to be closed if the provided context is cancelled or timed out before the result is received by the driver.

### Unicode support
Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
Other charsets / collations can be set using the [`charset`](#charset) or [`collation`](#collation) DSN parameter.
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
- 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.
