Dear All,
I am trying to use program to sign a piece of data using signedCms.ComputeSignature.
The certificate is in smart card and I use X509Store to select the certificate. Assigned the certificate to CmsSigner. However, it does not prompt me to enter the password. Is there anything I have missed?
It causes Cryptographic exception in signedCms.computeSignature.
Any tutorial website?
Thanks.
