Identify the likely hash algorithm (MD5, SHA-1/256/512, bcrypt, NTLM, etc.) from a hash string — 100% in your browser.
Paste one or more hash strings (one per line) and click Identify. The tool inspects length, character set and prefix to guess the algorithm — e.g. 32 hex = MD5/NTLM, 64 hex = SHA-256, $2b$ = bcrypt, $6$ = SHA-512 crypt. This is heuristic — several formats share the same length.
