How it works

Your password is stretched with PBKDF2-SHA256 (600,000 iterations and a random salt) into a 256-bit key. The text is then encrypted with AES-256-GCM, which also detects tampering or a wrong password. The output holds the salt, nonce, and ciphertext, so you need only the output and your password to decrypt.

There is no recovery. If you forget the password, the text is gone. Use a long password.
