#include <std/crypto/ec.h> source · definition

int ecdsa_verify(
    int curve,
    []const unsigned char pub,
    []const unsigned char hash,
    []const unsigned char r,
    []const unsigned char s,
)

ECDSA verification of 'hash' (truncated to the curve's size as FIPS 186-4 specifies) against (r, s) — each ec_scalar_size bytes — or a DER Ecdsa-Sig-Value. 1 if valid.
