How to use Hash Identifier

Paste a hash and the tool inspects its length and format to list the most likely algorithms that could have produced it.

Frequently asked questions

How does it identify a hash?

It examines the length, character set and any prefix (like $2b$ for bcrypt) to shortlist the algorithms that match.

Can it be certain of the type?

Not always — many algorithms share the same length. A 32-character hex string could be MD5 or an NTLM hash, so it lists candidates.

Does it crack the hash?

No — it only guesses the algorithm from the format; it does not attempt to reverse or crack the value.
