Hi,

Here is the scenario  -

I have priavte key stored on a Smart Card device on the client end. On the
server end the corresponding certificate is stored in the AD.

How do I retrive the relevant public Key from the certificate stored in AD?
I am able to extract the certificate from AD (get the byte stream) using LDAP.

But I am not sure that how do I extract the public key and encrypt the
message to send to the client. Every time I am creating an instance of
RSACryptoServiceProvider. It gives me new key pair.

I am using .Net Framework 1.1 and C Sharp.

Thanks
