lampshade

Package lampshade provides a transport between Lantern clients and proxies that provides obfuscated encryption as well as multiplexing. The protocol attempts to be indistinguishable in content and timing from a random stream of bytes, and mostly follows the OBFS4 threat model - https://github.com/Yawning/obfs4/blob/master/doc/obfs4-spec.txt#L35 Lampshade attempts to minimize overhead, so it uses less padding than OBFS4. Also, to avoid having to pad at all, lampshade coalesces consecutive small writes into single larger messages when there are multiple pending writes. Due to lampshade being multiplexed, especially during periods of high activity, coalescing is often possible.
