FYI, just landed a secp256k1 ECDSA implementation in #79.
There's also an open PR for P-256 which I'd like to take a swing at fixing up: #57
from elliptic-curves.
We definitely plan on adding ECDSA relatively soon. See the existing ECDSA crate:
https://github.com/RustCrypto/signatures/tree/master/ecdsa
The main issues to tackle are support for curve arithmetic which is generic over the underlying (Weierstrass) curve (#22) as well as access to the underlying (x-)coordinate(s) for AffinePoint
s in a safe, misuse-resistant way.
from elliptic-curves.
As of #101 and #104, ECDSA (with random k
only at present) is fully implemented.
#105 added initial documentation to the k256
crate.
Going to go ahead and close this issue. There's still more work to do (e.g. RFC 6979), but that will happen mostly upstream in the ecdsa
crate.
