WebMay 26, 2015 · SHA-256 is a hash function: it takes one input, and produces an output. If you feed SHA-256 with a password and a salt, then you are really defining your own cryptographic protocols, based on SHA-256 with some extra things, the extra things telling how the password and the salt are combined to make the SHA-256 input. Designing … WebSHA stands for secure hashing algorithm. SHA is a modified version of MD5 and used for hashing data and certificates. A hashing algorithm shortens the input data into a smaller form that cannot be understood by using bitwise operations, modular additions, and compression functions.
