About the Hash Identifier
Free hash identifier. Paste a hash and it guesses the algorithm — MD5, SHA-1, SHA-256, SHA-512, bcrypt, Argon2 and more — from its length, characters and prefix, and explains its structure. Runs in your browser.
How it works
- 1
Paste a hash
Any hex or crypt-format string.
- 2
See the guesses
Likely algorithms with confidence.
- 3
Read the structure
For bcrypt: cost, salt and hash.
Frequently asked questions
Not always — MD5 and NTLM share a length, for example. It reports the most likely candidates with a confidence level.
No. It only identifies the likely type and explains the format. Secure hashes can't be reversed.
