Python KeyAPI.ecdsa_verify Examples

Example #1

def verify(msghash: bytes, signature, public_key):
    """Verify that data has been signed with Etheruem private key.
    :param signature:
    :return:
    """
    key_api = KeyAPI('eth_keys.backends.NativeECCBackend')
    return key_api.ecdsa_verify(msghash, Signature(signature),
                                PublicKey(public_key))

Example #2

File: validateSignature.py Project: AYCH-Inc/aych.tron.ledger

def validate(transaction, signature, public_key):
    try:
        s = Signature(signature_bytes=signature)
        txID = hashlib.sha256(
            bytes.fromhex(transaction)
            if type(transaction) is str else transaction).digest()
        keys = KeyAPI('eth_keys.backends.NativeECCBackend')

        return keys.ecdsa_verify(txID, s, publicKey), txID.hex()
    except:
        return False, ""

Example #3

def validateHASH(txID, signature, public_key):

    keys = KeyAPI('eth_keys.backends.NativeECCBackend')
    publicKey = PublicKey(bytes.fromhex(public_key))
    return keys.ecdsa_verify(txID, s, publicKey)

Example #4

File: __init__.py Project: cchuang1024/nccu-tourbi-chain

def verify_signature(hash, sig, pub):
    keys = KeyAPI(NativeECCBackend)
    sign = keys.Signature(sig)
