[−][src]Crate ecdsa
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 Asn1Signature and FixedSignature types which are generic
over elliptic Curve types (e.g. NistP256, NistP384, Secp256k1)
which can be used in conjunction with the signature::Signer and
signature::Verifier traits to provide signature types which are
reusable across multiple signing and verification provider crates.
Transcoding between Asn1Signature and FixedSignature of the same
Curve type is supported in the form of simple From impls.
Additionally, the PublicKey and SecretKey types, also generic
over elliptic curve types, provide reusable key types, sourced from the
elliptic-curve crate. The PublicKey type supports both
compressed and uncompressed points, and for the P-256 curve in particular
supports converting between the compressed and uncompressed forms.
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.
TODO
- NIST P-521
- Brainpool
- Const generics(!)
