How to use this tool
Paste the exact text and choose an algorithm. Web Crypto hashes the UTF-8 bytes without trimming, newline conversion or Unicode normalization. The result is a lowercase hexadecimal digest. HTTPS and a modern browser are required. This is an unkeyed text hash, not password storage, an HMAC or a file checksum service.

Common questions
Does my input leave this page?
The tool processes its input in your browser. It does not send the text to our server for calculation. If advertising is enabled, third-party ad scripts also run on the page; use a trusted offline tool for secrets.
Can I use the result in my project?
Yes. Check the example and limitations first, and test the output with the system that will consume it.
