Golang secp256k1_ecdsa_verify Examples

Example #1

File: secp256k1.go Project: droark/go-secp256k1

func Verify(msgHash [hashLen]byte, sig []byte, pubkey []byte) bool {
	success := C.secp256k1_ecdsa_verify(cBuf(msgHash[:]),
		cBuf(sig),
		C.int(len(sig)),
		cBuf(pubkey),
		C.int(len(pubkey)))
	// success can be also -1 and -2 to indicate invalid sig or invalid pubkey
	// for now we just ignore that
	return goBool(success)
}

Example #2

// Verify ECDSA signature
func EC_Verify(pkey, sign, hash []byte) int {
	return int(C.secp256k1_ecdsa_verify((*C.uchar)(unsafe.Pointer(&hash[0])), C.int(32),
		(*C.uchar)(unsafe.Pointer(&sign[0])), C.int(len(sign)),
		(*C.uchar)(unsafe.Pointer(&pkey[0])), C.int(len(pkey))))
