(PowerBuilder) DKIM Signature using Windows Current User Certificate StoreThis is a Windows-specific example to load a certificate from the Current User (registry-based) certificate store, and then use the certificate's associated private key for a DKIM signature. Note: This example requires Chilkat v11.0.0 or greater.
