1 2 TODO 3 4#1 The encryption is really just a place-holder. link_verifier is meant 5 to be a per-message link-level verifier, meaning that the physical 6 link (a tcp connection in this case) can modify it and then use it as 7 a verifier on the other end. It should be set to 0 in the original 8 message. 9 10 This is not yet implemented. At the moment we rely on the 32-bit CRC 11 as our verifier, and it is not really good enough for the task. 12 13 - link verifier not yet implemented 14 - kill link on link verifier error 15 - Differentiate between end-to-end crc and link verifier 16 17#2 the circuit stuff is a bit of a mess. 18
