What does this tool do?
It generates common hash digests for any text, useful for integrity checks, signature debugging or learning. SHA uses the native Web Crypto API and MD5 is a pure-JS implementation — all local.
FAQ
Is my content uploaded?
No. All computation happens in your browser and nothing is sent to a server.
Is MD5 still safe?
MD5 is no longer suitable for security (collision attacks exist) but is still fine for integrity checks. For passwords or signatures, use SHA-256 or better.
