C# - Obtaining Digital Certificates from VeriSign and Verifying Authenticity

Question

Does VeriSign allow developers to obtain "sandbox" digital certificates which can be used in development, much like PayPal allows developers to set up sandbox accounts?

Furthermore, does anyone have an implementation in C# about how a client can send the certificate to a server, and the server checks with VeriSign that the digital certificate is valid?

Answer 1

You don't check with verisign, you use normal certificate validation (as you would with any other certificate).

A "sandbox" certificate is a self-signed certificate. You trust yourself (add your own certificate to the trusted root store) and so the certificate you signed yourself is trusted too.
