FAQ

Is hashing done locally?

Yes. We use the browser's Web Crypto API, so your text never leaves the page.

Which algorithms are supported?

SHA-256 and SHA-512 are available, plus SHA-1 for legacy checks only. Copy or download the output as needed.

Is there a size limit?

Keep input under 100,000 characters for best performance. Larger inputs may be blocked.
