Encryption and decryption happen entirely in your browser. Your plaintext and encryption key are never sent to our server.
Encrypt it here. Share it anywhere.
A password, a private message, a note you'd rather not leave lying around — lock it on your own device before you send it. Only someone with your key can read it back. No account, no install, nothing stored.
Why you can trust it
- Your data never leaves your device. The text you type is encrypted right here, in your browser. It's never uploaded — the only copy of the original stays in front of you.
- We don't store your data. We don't store your plaintext, encryption keys, or encrypted data on our servers — it's processed locally in your browser.
- Open and standard. We use AES-256-GCM through the browser's Web Crypto API — authenticated encryption that protects both confidentiality and integrity. How it works is fully documented, so your data stays unlockable with ordinary tools even if this site disappears.
Three ways to share it
Once it's encrypted, send it whichever way suits you. Your key always travels separately — a phone call, a text, in person.
- Copy the encrypted text. Paste it anywhere. The other person needs this site and the key.
- Send a link. The site is built in — they just add the key.
- Send a QR code. Same as the link, ready to scan from a phone.
Made for everyday privacy
You don't have to be a security expert — and neither does the person you're sharing with. This is for the ordinary moments when something just shouldn't travel as plain text:
- a password for a new account, sent over email
- a private note kept somewhere you don't fully control
- a message you'd rather not leave sitting in a chat history
Encrypt it, send the result however is convenient, and share the key through a different channel. That's it.
