PKI security for .net application

I want to use PKI public and private encryption for authentication to allow for a more streamlined 开发者_开发知识库and secure application access control system. Any help in the generation of certificate and authentication will be useful. One more question, can i use System.Security.Cryptography.X509Certificates class for the same?

Do you need to reinvent the wheel, all the above are possible with the existing framework IIS/ASP.NET/WCF.
