Thanks for your help.

I have another question regarding the cost of using Microsoft Certificate
Server.

I guess the use of the CryptoAPI for use in a standalone application to be
sold is free of charge. But what about setting up a MS certificate server
and ussing certificates? Does it cost something?

Thanks again
Eric
