01

Type your message

Your text never leaves your browser. Encryption happens locally using the Web Crypto API.

02

Get ciphertext + key

AES-256-GCM generates a unique encrypted blob and a one-time decryption key.

03

Send them separately

Email the ciphertext, text the key. Intercepting one is useless without the other.

04

Recipient decrypts

Paste both into the decrypt tab. Original message appears instantly — no account needed.
