Part 1 of your question - it's a big topic, but Wikipedia has some good reading explaining the differences:

http://en.wikipedia.org/wiki/X.509

http://en.wikipedia.org/wiki/PKCS_12

http://en.wikipedia.org/wiki/Distinguished_Encoding_Rules#CER_encoding

For Part 2 - yes it is possible to pass any arbitrary data from one computer to another on a network. How to do so depends on your programming language, network type (i.e. knowing what protocols are available), etc... Again, another big topic, but really we'd need to know more information about what you've tried, what language you are using, etc...

One possibility would be to use the ChilkatSocket object to transfer a certificate over TCP/IP, then on the server side import it into the server computer's certificate store.

Sorry, I now see you are using C++ (which is not my area of expertise). I'm sure other can help you if you show what you've tried so far, and explain how it's failed by posting error messages, and the contents of the LastErrorText property for whatever objects you are using at the point of failure.
