AESEncryptor class

Encrypt and decrypt text with AES-GCM.

Each message gets a new random 12-byte nonce. The output is base64 of nonce + ciphertext + tag. The 16-byte tag lets decode find any change to the text.

associatedData binds the text to a context, like a cookie name. It is not stored in the output. decode needs the same value, or it fails. So a value made for one cookie can not be used as another.
