(C#) DKIM Signature using Windows Current User Certificate Store

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.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Cert cert = new Chilkat.Cert();

// The LoadByCommonName method searches the Windows Local Machine and Current User 
// registry-based certificate stores for a certificate having the common name specified. 
// If found, the certificate is loaded and ready for use.
bool success = cert.LoadByCommonName("My Certificate ABC");
if (success != true) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

// The certificate must have an associated private key installed, and it must be a
// private key that has been marked "exportable" when it was originally installed.
if (!cert.HasPrivateKey()) {
    Debug.WriteLine("This certificate does not have a private key available.");
    return;
}

Chilkat.PrivateKey privKey = null;

privKey = cert.ExportPrivateKey();
if (cert.LastMethodSuccess == false) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

Chilkat.Dkim dkim = new Chilkat.Dkim();

// Load the private key into the DKIM object:
success = dkim.LoadDkimPk(privKey.GetPkcs8Pem(),"");
if (success != true) {
    Debug.WriteLine(dkim.LastErrorText);
    return;
}

// The private key has been loaded into the DKIM object.  See the other DKIM
// examples for guidance on how to create a DKIM signature...
