Hashing

Galois HASH (GHASH) and Rivest-Shamir-Adleman (RSA) are crypto systems hashing algorithms. Hashes are a fixed length string or number generated from a string of text. Algorithms, specifically hashing algorithms, are devised so that the resultant hashes cannot be reverse engineered. We use hashing to store passwords that are generated with a salt.

Salts, in cryptology, are random data used as an input to a hashing function to generate a password. Salts help protect against rainbow table attacks and dictionary attacks.

The following graphic illustrates the basics of how hashing works:

As you can see, the hashing algorithm is fed plain ...
