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. Swift

func chilkatTest() {
    var success: Bool = false

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

    let cert = CkoCert()!

    // 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.load(byCommonName: "My Certificate ABC")
    if success == false {
        print("\(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() {
        print("This certificate does not have a private key available.")
        return
    }

    let privKey = CkoPrivateKey()!
    success = cert.getPrivateKey(privKey: privKey)
    if success == false {
        print("\(cert.lastErrorText!)")
        return
    }

    let dkim = CkoDkim()!

    // Load the private key into the DKIM object:
    success = dkim.setPrivateKey(privateKey: privKey)
    if success == false {
        print("\(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...
