2//! Elliptic Curve Primitives
3//!
4//! This module provides constant-time implementations of elliptic curve operations
5//! on NIST curves P-224, P-256, P-384, and P-521. These implementations are designed
6//! to be resistant to timing attacks and provide a foundation for higher-level
7//! protocols like ECDH-KEM.
8//! This module now also includes support for Koblitz (secp256k1) and Binary (sect283k1) curves.
