Frequently asked questions

Is my text uploaded?

No. Hashing uses Web Crypto in your browser.

Why no MD5?

Web Crypto does not support MD5; it is also considered broken for security use.

Which hash should I use?

SHA-256 is a solid default for checksums and fingerprints.

Can I hash files?

This version hashes text input. File hashing can be added later.
