Text to encrypt

Password

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.

learning tips

🎓

Encrypt the same text twice — the output differs each time because of the random salt and IV.

🔬

A wrong password fails to decrypt rather than producing garbage, thanks to GCM authentication.

🧩

The output is base64 of salt + IV + ciphertext — a common real-world layout.

🔒

Experiment freely — nothing is uploaded.
