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. JavaScript

var success = false;

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

var cert = new CkCert();

// 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.
success = cert.LoadByCommonName("My Certificate ABC");
if (success == false) {
    console.log(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()) {
    console.log("This certificate does not have a private key available.");
    return;
}

var privKey = new CkPrivateKey();
success = cert.GetPrivateKey(privKey);
if (success == false) {
    console.log(cert.LastErrorText);
    return;
}

var dkim = new CkDkim();

// Load the private key into the DKIM object:
success = dkim.SetDkimPrivateKey(privKey);
if (success == false) {
    console.log(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...
