Everything about Message authentication code

Information used for message authentication and integrity checking

In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity-checking a message. In other words, it is used to confirm that the message came from the stated sender and has not been changed. The MAC value allows verifiers to detect any changes to the message content. Wikipedia →
