Crate ecdsa[−][src]
Expand description
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:
- ECDSA signature types alone which can be used to provide interoperability
between other crates that provide an ECDSA implementation:
p384
(NIST P-384)
Any crates which provide an implementation of ECDSA for a particular
elliptic curve can leverage the types from this crate, along with the
k256
, p256
, and/or p384
crates to expose ECDSA functionality in
a generic, interoperable way by leveraging the Signature
type with in
conjunction with the signature::Signer
and signature::Verifier
traits.
For example, the ring-compat
crate implements the signature::Signer
and signature::Verifier
traits in conjunction with the
p256::ecdsa::Signature
and p384::ecdsa::Signature
types to
wrap the ECDSA implementations from ring in a generic, interoperable
API.
Minimum Supported Rust Version
Rust 1.51 or higher.
Minimum supported Rust version may be changed in the future, but it will be accompanied with a minor version bump.
