SChannel ALPN support, documentation "bug"...

| 0 Comments

I'm looking at adding support for the TLS Application-Layer Protocol Negotiation Extension to The Server Framework as a precursor to looking into HTTP 2.0 support. This TLS extension is supported by both SChannel and OpenSSL. It's relatively new (only having been included in SChannel since June 2014 (!)) but there seems to be no documentation on MSDN for the structures and how to use them to add the appropriate entries to the TLS handshake and then to select and validate the protocol of your choice... Searching today with Google for something like "SEC_APPLICATION_PROTOCOL_NEGOTIATION_EXT" just gives just the usual selection of hits to people who think it's clever to run the Windows header files through their document generators and then publish the results on the web...

It's slightly easier with OpenSSL, but only because I can look at the source...

Anyway, long story short, I have the OpenSSL version working and am getting an HTTP 2.0 Connection Prefix from Chrome... I guess, for now, SChannel will have to wait.

I expect I'm being dense...
