Threat 1½: Tables for preditable salts If your salt is predictable (or known) then someone preparing to crack your website's passwords could generate tables to attack your specific website or specific users' passwords in advance of your password database getting ... Web3. Salts must be far more than unique. Salts protect against making a rainbow table, or some other form of pre-computed attack. If you never would have more than 10,000 users, a salt of 32 bits would be sufficient. But yet it'd be trivial to pre-compute all the values of a …
WebMar 24, 2024 · Thus you want a bare minimum of 40 bits of uniqueness, which requires an 80-bit salt. The current trend is to simply use a 128-bit random number, making the chance of a salt collision "cryptographically unlikely" for the near term. 80 bits would require random 14 alphanumeric characters. 128 bits requires 22 characters.
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.
