CMAC is a block cipher-based MAC algorithm specified in NIST SP 800-38B.A CMAC is the block cipher equivalent of an HMAC.CMACs can be used when a block cipher is more readily available than a hash function.

Write a program to compute simple interest and compound interest in python
CMAC is equivalent to OMAC1. To generate an ℓ-bit CMAC tag (t) of a message (m) using a b-bit block cipher (E) and a secret key (k), one first generates two b-bit sub-keys (k 1 and k 2) using the following algorithm (this is equivalent to multiplication by x and x 2 in a finite field GF(2 b)).

AES-CBC (cipher block chaining) mode is one of the most used symmetric encryption algorithms. The data size must be nonzero and multiple of 16 bytes, which is the size of a “block”. The data is split into 16-byte blocks before encryption or decryption is started, then the operation is performed on each of the blocks. HMAC Generator helps to generate HMAC using AES, MD5, SHA1, SHA3 and many more. Secure and one of the best tool. The National Institute of Standards and Technology (NIST) has recently specified the Cipher-based Message Authentication Code (CMAC), which is equivalent to the One-Key CBC MAC1 (OMAC1) submitted by Iwata and Kurosawa.

The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data published by the U.S. government as NIST standard in 2001. The standard comprises three block ciphers, AES-128, AES-192, and AES-256, adopted from a larger collection originally published as Rijndael.
