Hi Kishore,

I use {1,0,1} for the exponent, but I can't be 100% sure that it's the
correct way to go about it.

A quick question for you though. Have you tried to retrieve the matching
server certificate for the X509 cert?
I'd imagine that you're getting your a client cert via
Request.ClientCertificate and I need to retreive the matching server cert
and thus far can't see a way to do it :( .

Cheers
Allen
