uECC_verify() function
Verify an ECDSA signature.
Syntax
int uECC_verify(const uint8_t *p_public_key,
const uint8_t *p_message_hash,
unsigned int p_hash_size,
const uint8_t *p_signature,
uECC_Curve curve);
Implemented in ![]()
ecc_dsa.c:192
Return value
returns TC_SUCCESS (1) if the signature is valid returns TC_FAIL (0) if the signature is invalid.
Notes
Usage: Compute the hash of the signed data using the same hash as the signer and pass it to this function along with the signer's public key and the signature values (hash_size and signature).
