WebPublic-key cryptographic systems can often be used to provide authenticity. In PGP, this is allowed by the complementary nature of the public and private keys. In the beginning, two cryptographic keys are created, and either can be used as the public key; the choice as to which is the public key is really just an arbitrary assignment. WebIn cryptography, a message authentication code ( MAC ), also known as a tag, is used to authenticate a message or confirm that the message came from the stated sender and was not changed along the way.
