RustCrypto: ECDSA

Elliptic Curve Digital Signature Algorithm (ECDSA) as specified in FIPS 186-4 (Digital Signature Standard).

About

This crate provides generic ECDSA support which can be used in the following ways:

Generic implementation of ECDSA usable with the following crates:
- k256 (secp256k1)
- p256 (NIST P-256)
Other crates which provide their own complete implementations of ECDSA can also leverage the types from this crate to export ECDSA functionality in a generic, interoperable way by leveraging ecdsa::Signature with the signature::Signer and signature::Verifier traits.

Minimum Supported Rust Version

This crate requires Rust 1.57 at a minimum.

We may change the MSRV in the future, but it will be accompanied by a minor version bump.

License

All crates licensed under either of

at your option.

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.

`serde` support

When the serde feature of this crate is enabled, Serialize and Deserialize impls are provided for the Signature and VerifyingKey types.

Please see type-specific documentation for more information.

Interop

Any crates which provide an implementation of ECDSA for a particular elliptic curve can leverage the types from this crate, along with the k256, p256, and/or p384 crates to expose ECDSA functionality in a generic, interoperable way by leveraging the Signature type with in conjunction with the signature::Signer and signature::Verifier traits.

For example, the ring-compat crate implements the signature::Signer and signature::Verifier traits in conjunction with the p256::ecdsa::Signature and p384::ecdsa::Signature types to wrap the ECDSA implementations from ring in a generic, interoperable API.
