Crate 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 the Signature type with the signature::Signer and signature::Verifier traits.

Re-exports
