Hash Identifier

Paste one hash per line. The tool guesses the likely algorithm from its format — length, character set and prefix — and gives the hashcat mode where there is a clear one. Format is a strong hint, not proof: many algorithms share a length (a 32-hex string could be MD5, NTLM, MD4 or LM). Everything runs in your browser; nothing is sent anywhere.
