Hash generator & identifier

Hash text or a file to verify a download against its published checksum, or paste an unknown hash to see what produced it. Files are read and hashed on your device — they are never uploaded.

Generate a hash

Text (hashed as UTF-8, exactly as typed — including any trailing newline)

MD5 and SHA-1 are broken: attackers can craft two different inputs with the same hash. They are still fine for spotting accidental corruption, not for proving a file wasn't tampered with. And no plain hash — SHA-256 included — is suitable for storing passwords; that needs a slow, salted algorithm such as Argon2id or bcrypt.

Identify a hash

Matches the value's shape — its prefix, length and characters — against known formats. A raw hex digest doesn't record which algorithm made it, so several candidates are often equally possible.
