Summary: The CryptoFactory is extended with makePacketNumberCipher . In order to support that feature, FizzCryptoFactory now explicitly takes a QuicFizzFactory as argument instead of a generic fizz::Factory, which is the only type that is used in practice anyways. The cypher argument was removed because: 1/ Only one cypher is used at all. Fizz also supports ChaCha20, but using it in mvfst will throw an exception. 2/ it seems like the factory should know what cypher it is dealing with. If a choice of cypher needs to be supported going forward, it can be done by adding state to FizzCryptoFactory.
