RustCrypto: NIST P-384 (secp384r1) elliptic curve

crate Docs Build Status Apache2/MIT licensed Rust Version Project Chat

Pure Rust implementation of the NIST P-384 (a.k.a. secp384r1) 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.

About P-384

NIST P-384 is a Weierstrass curve specified in SP 800-186: Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters.

Also known as secp384r1 (SECG), it’s included in the US National Security Agency’s “Suite B” and is widely used in protocols like TLS and the associated X.509 PKI.

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.
