Hi.
We got a smart key card that holds Private Key for signature certificate.
Via the GUI of the smart card we can sign a document.
How can the verifying side verify the validity of the certificate too (programatically)
How could be the CA queried for the validity of the certificate
Should that particular person's certificate be present in the X509Store beforehand
Thanks in advance.

SignedCms + X509ChainPolicy + X509Certificate2.Verify()

Actually seems there is already answer for this that I found after the post.
