WebApr 22, 2012 · Ugh, no. Salting only means you can’t precalculate the one billion hashes associated with the one billion possible SSN’s. It doesn’t mean you can’t brute force a particular SSN# given the salt with a 2^30 (small) work effort. It’s not meaningful to discuss salts being kept secret.
WebAug 21, 2024 · Salted passwords can still be bruteforced individually. In practice, hash sizes of 32 bytes are fairly common, as really short hashes are still vulnerable to rainbow tables. And don’t reuse salts; you should generate a new random string each time.
