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, only the output from an invocation of a cryptographic hash function on the password was stored on a system, but, over time, additional safeguards were developed to protect against duplicate or common passwords being identifiable (as their hashes are identical).
