Online Hash Identifier
Paste a hash and this tool will guess the likely algorithm that produced it (e.g. MD5, SHA-256) based on its length and format. Handy when you find an unlabeled hash. Everything runs in your browser.

About Hash Identifier
The Hash Identifier guesses which algorithm likely produced a hash by analyzing the string length and pattern. For example, 32 hex characters are typical of MD5, 40 characters of SHA-1/RIPEMD-160, and 64 characters of SHA-256/SHA3-256/BLAKE2s.
This identification is heuristic: several algorithms produce the same length, so the tool returns a list of candidates rather than a single answer. For prefixed formats like bcrypt ($2b$) or Argon2 ($argon2id$), the tool recognizes them directly.
FAQ
Is the result always correct?
Not always. Because many algorithms share the same output length, the tool gives candidates based on length. Additional context is needed for certainty.
