Hash Identifier

Find out which algorithm produced a hash and how to feed it to hashcat and John the Ripper. Shows every matching type honestly.

Hashes are not sent anywhere: the type is detected right in your browser. The -m and --format tags tell hashcat and John the Ripper the hash type; click to copy.

The tool reads a hash string and names the algorithm that produced it, showing how to set that type in hashcat and John the Ripper.

Honest answers, not guesses

Only formats with a prefix have a definitive answer, and the tool names them unambiguously:

  • “$2y$” — bcrypt;
  • “$6$” — sha512crypt;
  • “{SSHA}” — salted SHA1.

A plain hexadecimal hash cannot be identified with certainty: MD5, NTLM, and MD4 all produce 32-character strings, so they look identical. The tool lists every matching type and says so openly instead of passing off the first match as the answer. That is what sets it apart from other identifiers that confidently label any 32-character string as “MD5”.

Multiple hashes at once

Paste one hash per line and the tool examines each one and shows a short answer. Identifying the type by its looks is possible here; recovering the password from the hash is a different task and is not what this tool does.
