Text Encrypt / Decrypt (AES)
Protect a message with AES encryption and a password, then share the ciphertext safely; decrypt it back with the same password. Everything runs locally, so your text and password never leave your device.
Uses AES with a password-derived key, entirely in your browser — nothing is uploaded. Share the password over a separate, secure channel.

Frequently asked questions
How secure is it?＋
It uses AES with a key derived from your password. Security depends on using a strong, unique password — a weak one can be brute-forced.
Can I recover text if I forget the password?＋
No. Without the exact password the ciphertext cannot be decrypted, so store the password safely.
Is anything uploaded?＋
No — encryption and decryption run entirely in your browser. Share the password over a separate secure channel from the ciphertext.
