Cryptographic salting
WebIn 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 … WebAug 25, 2010 · The purpose of salting is to defeat a dictionary attack. Instead of creating a dictionary of hashed passwords and then simply looking for matches all over the place, you force the attacker to recompute all the hashes for each unique salt.

WebSalt is random data that helps protect against dictionary and other precomputation attacks. Generally, salt is used in password-based systems and is concatenated to the front of a password before processing. Password systems often use a one-way hash function to turn a password into an “authenticator.” WebJul 29, 2024 · Salting is a process that combines the password with a random numeric value (the salt) before computing the one-way function.
