Donaldson R F Text Encryption (AES)
Encrypt text with a password using real AES-256 encryption, or decrypt it back with the same password.
This uses AES-GCM encryption with a password-derived key (PBKDF2, 100,000 iterations) — real, standard cryptography, computed entirely in your browser. The password is never sent anywhere. If you forget the password, the text cannot be recovered.
