[Edwards Digital Signature Algorithm (EdDSA)][1] over Curve448 as specified
in [RFC 7748][2].

[Documentation][docs-link]

## About

This crate doesn't contain an implementation of Ed448, but instead
contains an [`ed448::Signature`][3] type which other crates can use in
conjunction with the [`signature::Signer`][4] and [`signature::Verifier`][5]
traits.

These traits allow crates which produce and consume Ed448 signatures
to be written abstractly in such a way that different signer/verifier
providers can be plugged in, enabling support for using different
Ed448 implementations, including HSMs or Cloud KMS services.

## 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](http://www.apache.org/licenses/LICENSE-2.0)
 * [MIT license](http://opensource.org/licenses/MIT)

at your option.

### Contribution

Unless you explicitly state otherwise, any contribution intentionally submitted
