+ This interface provides for datagram encapsulation for SOCKSv5 protocol.

+ SOCKSv5 allows for datagrams to be encapsulated for purposes of integrity

+ and/or authenticity. How it should be done is aggreed during the 

+ authentication stage, and is authentication dependent. This interface is

+ provided to allow this encapsulation.
