DKIM Signature using Windows Current User Certificate Store

See more DKIM / DomainKey Examples

This 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. Chilkat2 Java
