[−][src]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)
ECDSA signature types alone which can be used to provide interoperability between other crates that provide an ECDSA implementation:
- p384 (NIST P-384)
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.
