RustCrypto/signatures — Cryptographic signature algorithms: DSA, ECDSA, Ed25519

Description and use

RustCrypto’s **signatures** crate provides pure‑Rust implementations of widely used cryptographic signature schemes, including DSA, ECDSA, and Ed25519. It offers a clean, algorithm‑agnostic API that integrates with the broader RustCrypto ecosystem, supporting both signing and verification with safe, constant‑time operations. The library is fully open‑source, well‑tested, and suitable for security‑critical applications.

Problem

RustCrypto/signatures may be useful when its README and activity match a concrete workflow.

Outcome

Early or unclear: treat as research material until maintenance, releases, docs, and issue activity are verified.

Evidence
