Hash generator

Generate SHA-256 digests for text using your browser's built-in cryptography, plus MD5 via a simple implementation where available. MD5 and SHA-1 are legacy checksums, not secure hashing.

How to use Hash generator

Type the text to hash.
Generate its SHA-256 digest (and MD5 where available).
Compare the digest against the one you were given to check a file or string matches.

A good use for this

Checking that a download, a password, or a string has not been altered, by comparing digests.

Limits

MD5 and SHA-1 are legacy checksums, not secure hashing — they must not be used for passwords or security decisions. A matching digest proves the text matches, not that the text itself is trustworthy.
