Pure Rust digital signature library with support for elliptic curve digital signature algorithms, namely ECDSA (FIPS 186‑4) and Ed25519 (RFC 8032).
About
This crate provides a thread-and-object-safe API for both creating and verifying elliptic curve digital signatures, using either software-based or hardware-based providers.
The following algorithms are supported:
- ECDSA: Elliptic Curve Digital Signature Algorithm (FIPS 186‑4)
- Ed25519: Edwards Digital Signature Algorithm (EdDSA) instantiated using the twisted Edwards form of Curve25519 (RFC 8032).
Minimum Supported Rust Version
Rust 1.65 or newer.
In the future, we reserve the right to change MSRV (i.e. MSRV is out-of-scope for this crate's SemVer guarantees), however when we do it will be accompanied by a minor version bump.
