Cryptographic salts are broadly used in many modern computer systems, from Unixsystem credentials to Internet security. Salts are closely related to the concept of a cryptographic nonce. Example usage[edit] Here is an incomplete example of a salt value for storing passwords. This first table has two … See more 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 … See more To understand the difference between cracking a single password and a set of them, consider a file with users and their hashed passwords. Say the file is unsalted. Then an attacker could pick a string, call it attempt[0], and then compute hash(attempt[0]).
