Encrypt & Decrypt Text with a Password

Encrypt a message with a password using AES-256-GCM, then decrypt it with the same password. Everything happens on your device.

Tip from Tink: Share the password by a different route than the message.

Text to encrypt

Encrypted (safe to send)

Password

Uses AES-256-GCM with a key made from your password (PBKDF2, 310,000 rounds). Send the password through a different channel than the message. If it's lost, the text can't be recovered.

🔒 Runs entirely on your device. Nothing you type is sent anywhere or saved.
