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. Go

    success := false

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

    cert := chilkat.NewCert()

    //  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 {
        fmt.Println(cert.LastErrorText())
        cert.DisposeCert()
        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() {
        fmt.Println("This certificate does not have a private key available.")
        cert.DisposeCert()
        return
    }

    privKey := chilkat.NewPrivateKey()
    success = cert.GetPrivateKey(privKey)
    if success == false {
        fmt.Println(cert.LastErrorText())
        cert.DisposeCert()
        privKey.DisposePrivateKey()
        return
    }

    dkim := chilkat.NewDkim()

    //  Load the private key into the DKIM object:
    success = dkim.SetDkimPrivateKey(privKey)
    if success == false {
        fmt.Println(dkim.LastErrorText())
        cert.DisposeCert()
        privKey.DisposePrivateKey()
        dkim.DisposeDkim()
        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...

    cert.DisposeCert()
    privKey.DisposePrivateKey()
    dkim.DisposeDkim()
