Unlike, say an md5 signature, it's generated using a secret key known only to you and the receiving party so that it shouldn't be possible to forge by a third party. 3 Vocabulary. Hashing for Message Authentication Codes. Antonyms for message. Antonyms for Message board. A message authentication code (MAC) is a short fixed-length value which is used to authenticate a message.A MAC algorithm can roughly be viewed as a hash function that takes as input two functionally distinct values: a secret key and a message. It should always be possible to see the sender computer IP address aaa.aaa.aaa.aaa and the sender mail server bbb.bbb.bbb.bbb, if the message was sent from a mail client and a client computer. The text message goes to a previously registered phone. 1 In cryptography, a message authentication code (MAC), sometimes known as a tag, is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed. You can use this number to receive an authentication code if you ever lose access to the Google Authenticator app or reformat your device.
