WebMar 14, 2024 · Hashing differs significantly from encryption, however, in that it is a one-way process. There is no easy way to unscramble the data, interpret the output, or reverse-engineer the input. There’s no key, no system of two keys, no publicly-accessible keys, no certificates that will grant you access to the original data. WebJan 19, 2024 · Some of MACs are HMAC (Hash-based MAC), CMAC (Cipher-based MAC), Poly1305. Here we will be discussing the HMAC, Poly1305, and BLAKE2 as a substitute for HMAC. Let’s see an example of HMAC.
