RustCrypto: ECDSA

crate Docs Apache2/MIT licensed MSRV Project Chat Build Status

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



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

  • Generic implementation of ECDSA usable with the following crates:
  • 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 1.51 at a minimum.

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