A cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size alphanumeric string, which is called the hash value (sometimes called a message digest, a digital fingerprint, a digest or a checksum)

A cryptographic hash function an algorithm to convert data like a password into a fixed length sting of characters called a fingerprint. Salting is a way to randomize hashes by adding a random string (which is called a salt) before a password is hashed, w

All of the above

A cryptographic hash function is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string.
