What does Hash Identifier actually do?

The hash identifier guesses algorithms from a digest’s length and alphabet. A 32-hex string can be MD5 and also many other 128-bit values. The tool lists candidates. It does not crack the hash or confirm which algorithm was used.

When should I use Hash Identifier?

Use it when a log shows a hex string and you want plausible algorithms.

When should I not use Hash Identifier?

Do not treat the first guess as proof.

What does Hash Identifier not do?

Length collisions are common. A guess is not an identification. Does not reverse the preimage.
