RustCrypto: NIST P-521 (secp521r1) elliptic curve
Pure Rust implementation of the NIST P-521 (a.k.a. secp521r1) elliptic curve.
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.

- Elliptic Curve Diffie-Hellman (ECDH): gated under the
ecdhfeature. - Elliptic Curve Digital Signature Algorithm (ECDSA): gated under the
ecdsafeature.
NIST P-521 is a Weierstrass curve specified in SP 800-186: Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters.
Also known as secp521r1 (SECG).
