Share a Secret Safely

Encrypt a password or note to send over chat or email.

Strong, standard encryption: AES-256-GCM with a key derived from your password via PBKDF2 (250,000 iterations, SHA-256). Each message uses a fresh random salt and IV.

The password is never stored or sent anywhere — everything runs in your browser. If you lose the password, the message cannot be recovered. Share the encrypted text and the password through separate channels.

secrets tips

🔑

Send the encrypted text and the password through different channels (e.g. email the text, text the password).

🔒

AES-256-GCM means even if the message is intercepted, it's unreadable without the password.

⏱️

Agree on the password in advance or via a call — never in the same message as the ciphertext.

💻

Both encryption and decryption run in your browser.
