Sorry I'm not sure what you are trying to say here:

That would be Wireshark if the code was included, wouldn't it?
I'm not willing to committ any code as long as I'm unsure about the implications of doing so.
If some one feels confident that this is no problem they can committ code to do the decryption.
If you feel thet the dissector should not continue to go in this direction we can keep it private.
Best regards

We are stuck with technology when what we really want is just stuff that works. Some say that should read Microsoft instead of technology.
