Encrypt or decrypt text with password-protected AES-GCM, directly in your browser. A simple way to protect a note, a message or a key before sharing it. No text or password is ever transmitted: everything stays on your machine.
What is it for?
- ▸ Protect a sensitive note before archiving it
- ▸ Encrypt a message before sending it by email
- ▸ Secure a shared key or secret

FAQ
Which algorithm is used?
AES-GCM, a standard authenticated encryption mode, with a key derived from your password (PBKDF2).
What happens if I forget the password?
The text cannot be recovered without the password. Keep it safe.
Is my data sent anywhere?
No. Encryption runs locally in your browser, with no server involved.
