func chilkatTest() {
    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let rsa = CkoRsa()!

    // First demonstrate importing a PEM public key:
    var publicKeyPem: String? = "PEM public-key data goes here"
    let pubkey = CkoPublicKey()!

    var success: Bool = pubkey.load(from: publicKeyPem)
    if success != true {
        print("\(pubkey.lastErrorText!)")

    var publicKeyXml: String? = pubkey.getXml()

    success = rsa.importPublicKey(publicKeyXml)
    if success != true {
        print("\(rsa.lastErrorText!)")
        return
    }

    // Demonstrate importing a PEM private key:
    var privateKeyPem: String? = "PEM private-key data goes here"
    let privkey = CkoPrivateKey()!

    // If the private key PEM is protected with a password, then 
    // call LoadEncryptedPem.  Otherwise call LoadPem.
    success = privkey.loadPem(privateKeyPem)
    if success != true {
        print("\(privkey.lastErrorText!)")
        return
    }

    var privateKeyXml: String? = privkey.getXml()
    success = rsa.importPrivateKey(privateKeyXml)

        return
    }

    print("OK!")
