Re: [ogpx] Fwd: Context for Service Establishment in OGP

["Hurliman, John" <[e-mail]>]

(I made the same mistake in response)

If it's of any use, I wrote a C# library called OpenMetaverse.Http that is capable of generating root certificates and signed client certificates that can be fed into HttpWebRequest as an SSL client cert, plus some basic routines for doing the cert checks on the server. Right now it's only doing a very crude check to make sure the root certificate shows up somewhere in the certificate chain of the client cert and that the chain is valid. No revocation checks or anything.
