Certificate Class

Use the Certificate property of the Signature object to return a Certificate object.

This type or member can be accessed only from code running in forms opened in Microsoft Office InfoPath 2007.

In the following example, the Status property of the Certificate class is used to determine the status and other information about the digital certificate used for the first signature on the first set of signed data (or for the entire form, if the entire form is configured to be signed), and display that information in a message box.

public void CertificateStatusAlert()
{
    Certificate myCertificate = 
       this.SignedDataBlocks[0].Signatures[0].Certificate;
    MessageBox.Show("IssuedTo: " + myCertificate.IssuedTo + 
        "\nIssuedBy: " + myCertificate.IssuedBy + 
        "\nExpirationDate: " + myCertificate.ExpirationDate + 
        "\nStatus: " + myCertificate.Status.ToString());
}
