Cool! I looked at the cryptography but never got a chance to prove if
GnuTLS allowed it. DES-CBC with an all-zero IV seems to be just DES at
a maths level, so if that works we should be able to just use GnuTLS!
Sadly MSCHAPv2 is so well embedded that I don't think we will be rid of
DES or NTLM any time soon, but I certainly hope we can stop carrying
the crypto code for it.
