ecdsa crate
Elliptic Curve Digital Signature Algorithm (ECDSA) as specified in FIPS 186-4 (Digital Signature Standard).
This crate doesn't contain an implementation of ECDSA itself, but instead
contains ecdsa::Asn1Signature and ecdsa::FixedSignature types
generic over an ecdsa::Curve type which other crates can use in
conjunction with the signature::Signer and signature::Verifier
traits.
These traits allow crates which produce and consume ECDSA signatures to be written abstractly in such a way that different signer/verifier providers can be plugged in, enabling support for using different ECDSA implementations, including HSMs or Cloud KMS services.
