Limitations
- ! Lose the password and the text is unrecoverable; there is no reset.
- ! The ciphertext is safe to send, but the password must travel over a different channel.
FAQ
Which algorithm is used?
AES-256-GCM with a key derived from your password by PBKDF2 with 150,000 iterations.
Is the password stored?
No, it stays in the page and is never written anywhere.
Can you recover my text?
No. Nobody at this site can decrypt it.
Files never leave your device
Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
