Hash Type Identifier
Paste a hash to see the likely algorithms from its length and format.
What kind of hash is this?
Faced with an unlabelled hash, the first question is which algorithm produced it. Length and format give it away: this tool reads those clues and lists the algorithms that fit, which is the starting point for any hash work.
The 32-hex-character 5f4dcc3b5aa765d61d8327deb882cf99 matches MD5 (and shares that length with NTLM and MD4). Prefixes like $2b$ point to bcrypt and $6$ to sha512crypt.
Classification only, kept private
It never tries to reverse the hash — that is not possible — and the analysis runs in your browser with nothing uploaded.
Frequently Asked Questions
How does it identify a hash?
By its length and character set, plus recognisable prefixes. A 32-character hex string is likely MD5; a $2b$ prefix is bcrypt. It lists the plausible candidates.
Can it reverse or crack the hash?
No. Hashes are one-way, and this only classifies the format. It never attempts to recover the original input.
Why several candidates?
Different algorithms can share a length — 32 hex characters fits MD5, NTLM, and MD4 — so the tool shows all that match.
