A quick web search turned up a few discussion forums threads with a 
recipe for this (e.g 
https://stackoverflow.com/questions/1231178/load-an-x509-pem-file-into-windows-cryptoapi). 
There's no direct "read this file" function, but there are low-level 
functions that can decode the file format once it's read into memory. So 
it seems possible to make it work.

Once we've modified the client to support multiple libraries, it's 
probably not much extra effort to do the same to the server. I wouldn't 
like to support different libraries in client and server, if only 
because it would be more complicated to have separate ./configure 
options for client and server.
