RustCrypto: NIST P-224 (secp224r1) elliptic curve

Pure Rust implementation of the NIST P-224 (a.k.a. secp224r1) elliptic curve with support for ECDH, ECDSA signing/verification, and general purpose curve arithmetic support implemented in terms of traits from the elliptic-curve crate.

Documentation

⚠️ Security Warning

The elliptic curve arithmetic contained in this crate has never been independently audited!

This crate has been designed with the goal of ensuring that secret-dependent operations are performed in constant time (using the subtle crate and constant-time formulas). However, it has not been thoroughly assessed to ensure that generated assembly is constant time on common CPU architectures.

USE AT YOUR OWN RISK!

Supported Algorithms

• Elliptic Curve Diffie-Hellman (ECDH): gated under the ecdh feature.
• Elliptic Curve Digital Signature Algorithm (ECDSA): gated under the ecdsa feature.

About P-224

NIST P-224 is a Weierstrass curve specified in SP 800-186: Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters.

Also known as secp224r1 (SECG).
