Hash Generator & Identifier
Generate MD5 / SHA family hashes, identify unknown hash strings by pattern, and verify bcrypt / Argon2 password hashes. Hash generation runs entirely in your browser.

Password storage: MD5 and SHA family hashes are never appropriate for storing passwords — they are too fast, enabling billions of guesses per second on commodity hardware.
Use bcrypt, Argon2id, or scrypt (NIST SP 800-63B §5.1.1.2).
Hash Identifier
Paste a hash to identify its algorithm from length, character set, and prefix patterns
Type or paste a hash above to identify it.
Password Hash Verifier
bcrypt and Argon2 are CPU/memory-hard — verified server-side
bcrypt unavailable
Argon2 unavailable
bcrypt truncates passwords at 72 bytes — characters beyond that are ignored.
