- When the published address is "NTCP", Bob supports both NTCP and SSU2 on the
same port. For compatibility, when initiating a connection to an address
published as "NTCP", Alice must limit the maximum size of this message,
including padding, to 287 bytes or less. This facilitates automatic protocol
identification by Bob. When published as "SSU2", there is no size
restriction. See the Published Addresses and Version Detection sections
below.
- The unique X value in the initial ChaCha20 block ensure that the ciphertext is
different for every session.
