There are several types of CTS approaches. Only three of those are listed in 
the SP800-38A addendum. The source code only refers to some RFCs.

Did you check whether the CTS implementation matches one or more of the types 
listed in the addendum? If yes, may I suggest to add a small statement in the 
code noting this fact?

Thanks a lot.
