Hash Identifier
Paste a hash and identify its likely type · MD5, SHA-1/256/512, NTLM, bcrypt, crypt, MySQL and more. Everything runs in your browser · no data is uploaded.

How to use
1
Paste the hash
Drop a single hash into the input box.
2
Read candidates
The tool ranks the most likely algorithms by format and length.
3
Use context
Where you found the hash narrows ambiguous matches like MD5 vs NTLM.

Frequently Asked Questions
It inspects the length, character set and prefix of the string to determine which algorithms could have produced it. Because many algorithms share an output length, the result is a ranked list of candidates rather than a single definitive answer.
Not from the hash alone · both produce a 32-character hex string and are indistinguishable by format. The context where you found the hash (a Windows SAM dump vs a web app) usually decides which one it is.
No. All detection runs locally in your browser. Nothing is uploaded or logged.
Output length and encoding are not unique to one algorithm. A 64-character hex string could be SHA-256, SHA3-256, BLAKE2s, RIPEMD-256 and others, so the identifier ranks the most common ones first.
