Hash text
Paste some text and get its digest with four algorithms. It is for comparing: if your value matches the published one, you have the same text.
Your text stays on your device: nothing is uploaded
Result
Paste something on the left: the result appears as you type.
How it works
A digest is a short number that depends on every single byte of the text: change one and the whole thing changes. It lets you compare two things without putting them side by side. SHA-1, SHA-256 and SHA-512 are computed by the browser’s own cryptography library, the same one it uses for secure connections. MD5 is not: no browser implements it any more, and for good reason — it has been broken for twenty years, and two different files with the same digest can be constructed on purpose. We wrote it ourselves because it is still what websites print next to their downloads, and whoever comes here wants to check that string. Use it for that, never to protect a password: passwords need deliberately slow algorithms like bcrypt or Argon2, which have nothing to do with these. The text never leaves this page, so you can paste something confidential.
What you paste is never uploaded. Anywhere.
Not to a server of ours, not to a third party, never. The text you type stays in your browser’s memory: it is read, processed and shown here, and you copy it. There is no path that takes it elsewhere, because there is no server to send it to. You can paste something confidential.
- Processed locallyThe computation happens on this page, using the browser’s own engine: no request goes out while you type.
- Nothing to upload, nothing to wait forOther services send your file to a server and then send it back to you. Here the file never leaves: there is no upload to wait for.
- No accountNo sign-up, no email, no daily limits to get around by paying.
- Nothing to deleteOthers promise to delete what you paste after an hour. We have nothing to delete: it never reached us.
