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.
⚠️ 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).
Minimum Supported Rust Version
Rust 1.65 or higher.
Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.
