Module ec 

Elliptic Curve Primitives

This module provides low-level elliptic-curve operations on several curves. Individual implementations use timing-aware techniques, but the module has no blanket compiler- or target-level constant-time guarantee and is not by itself a complete protocol such as RFC 9180 HPKE. The prime curves retained for v3 are P-224, P-256, P-384, P-521, and secp256k1. P-192 and sect283k1 were removed: P-192 is legacy-only in NIST SP 800-186, while the previous sect283k1 implementation used an incorrect group order and did not validate subgroup membership.
