WebOct 14, 2024 · Abstract. Signed messages are widely used in network security. A message is typically signed by the sender with semantically-secure signature algorithms, and then verified by any receiver which is configured with the sender’s public key. A successfully-verified message ensures data origin authentication and data integrity. WebIn http-message-signatures, you can ensure that the information signed is what you expect to be signed by only trusting the data returned by the verify() method: verify_result = verifier.verify(request) This returns VerifyResult, a namedtuple with the following attributes: label (str): The label for the signature
