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

    let rsa = CkoRsa()

    // Generate a 1024-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 4096 bits.
    var success: Bool = rsa.GenerateKey(1024)
    if success != true {
        print("\(rsa.LastErrorText)")
        return
    }

    // Keys are exported in XML format:
    var publicKeyXml: String? = rsa.ExportPublicKey()
    print("\(publicKeyXml!)")

    var privateKeyXml: String? = rsa.ExportPrivateKey()
    print("\(privateKeyXml!)")

    // Save the private key in PEM format:
    let privKey = CkoPrivateKey()
    success = privKey.LoadXml(privateKeyXml)
    success = privKey.SavePemFile("privateKey.pem")

    // Save the public key in PEM format:
    let pubKey = CkoPublicKey()
    success = pubKey.LoadFromString(publicKeyXml)
    success = pubKey.SavePemFile(false, path: "publicKey.pem")
