About

This crate doesn't contain an implementation of Ed25519, but instead contains an ed25519::Signature type which other crates can use in conjunction with the signature::Signer and signature::Verifier traits.

These traits allow crates which produce and consume Ed25519 signatures to be written abstractly in such a way that different signer/verifier providers can be plugged in, enabling support for using different Ed25519 implementations, including HSMs or Cloud KMS services.

Minimum Supported Rust Version

This crate requires Rust 1.72 at a minimum.

Our policy is to allow MSRV to be raised in future released without that qualifing as a SemVer-breaking change, but it will be accompanied by a minor version bump, ensuring if you lock to a minor version MSRV will be preserved for the default feature set.

SemVer Policy

• All on-by-default features of this library are covered by SemVer
• MSRV is considered exempt from SemVer as noted above
• The pkcs8 module is exempted as it uses a pre-1.0 dependency, however, breaking changes to this module will be accompanied by a minor version bump.

License

All crates licensed under either of

• Apache License, Version 2.0
