Password salting is a technique where a random string of characters are added to the password before calculating their hashes.Advantage: Salting makes it more difficult to reverse the hashes and defeat pre-computed hash attacks.
Defend against Password Cracking
Use a random string (salt) as a prefix or suffix to the password before encryption. (P.617/601)
In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically a password was stored in plaintext on a system, but over time additional safeguards were developed to protect a user's password against being read from the system. A salt is one of those methods.
