Hash generator

Hash text or a whole file, and check the result against a checksum you were given — it tells you plainly whether they match. SHA digests come from the browser’s own crypto engine; MD5 and CRC32 are implemented here, since neither is a security primitive and neither is available in it.

Runs entirely in this tab. What you paste is never sent anywhere.

Text to hash

Paste, type, or drop a file (json, txt, yaml, yml, csv, log).

Compare against a checksum

Case and whitespace are ignored, and a trailing filename is fine — paste the whole line from a SHA256SUMS file if that is what you have.
