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.
The following graphic illustrates the basics of how hashing works:
As you can see, the hashing algorithm is fed plain ...
