Hash Identifier

Hash Identifier inspects a hash’s length, character set, and prefix to list the most likely algorithms (MD5, SHA-1/256/512, NTLM, bcrypt, Argon2, crypt $1$/$5$/$6$, CRC, and more). It only analyzes patterns — no cracking — and runs entirely in your browser.

Paste a hash and find out what it probably is. This identifier analyzes the length, character set, and any prefix of a hash to list the most likely algorithms — MD5, SHA-1, SHA-256/512, NTLM, bcrypt, Argon2, the Unix crypt family ($1$/$5$/$6$), CRC, and more. It’s a fast first step for CTFs, pentesting write-ups, log analysis, and figuring out how a password was stored. It only inspects patterns (it never cracks or reverses anything), and everything runs locally in your browser.
