The algorithm takes the plain text in 64-bit blocks and converts them into ciphertext using 48-bit keys. WebCipher-based message authentication codes (or CMACs) are a tool for calculating message authentication codes using a block cipher coupled with a secret key. You can use an CMAC to verify both the integrity and authenticity of a message. A subset of CMAC with the AES-128 algorithm is described in RFC 4493. how to dispose of de razor blades
