That's a cool idea, but where's the fun in that? :)

Hmm... This part of the thread has strayed way off topic. o.O Just 
noticed the title had something to do with cryptography...

Wikipedia claims OpenVPN uses the OpenSSL library.

Still unclear how it runs SSL over UDP...

http://openvpn.net/index.php/documentation/manuals/openvpn-21.html - 
under "Description":

"OpenVPN is tightly bound to the OpenSSL library, and derives much of its 
crypto capabilities from it."

From the above quote, it maybe doesn't, but instead uses the crypto from 
openSSL.

Well, if you consider going to the ER for burns fun, then have at it.  I 
have different ideas of what constitutes "fun", and not being burned is a 
part of all of them. ;-)

Then you need to make your voice heard.  Tell the auditor "HQ won't let 
me - I've tried telling them and they don't listen to me - so talk to 
them" and then wait.

One of two possible outcomes:  The boss will start listening to you, or 
the boss will get pissed off and sack you (which means you don't have to 
do the 6 month notice thing or find your own replacement, right?) so 
you're free to find something else to do.
