The .wrap() method creates an LLEncrypt.Key or LLEncrypt that generates an
IV for each message before encryption, and updates the internal state of this class after
encryption. Typically, a separate IVGen instance should be used for each key.
If a message presented for encryption already has an IV associated, it would bypass this class.
In that case, the IV is not checked and the internal state is not updated.
Initialization Vector generator.
