func chilkatTest() {
    // 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
    }

    // Get the private key as unencrypted XML:
    var keyXml: String? = rsa.ExportPrivateKey()
    print("\(keyXml!)")

    // To encrypt the key -- meaning to get the key in
    // an encrypted PEM format -- load it into a PrivateKey object,
    // and then export to encrypted PEM:
    let privKey = CkoPrivateKey()

    success = privKey.LoadXml(keyXml)
    if success != true {
        print("\(privKey.LastErrorText)")
        return
    }

    var strEncPem: String?

    strEncPem = privKey.GetPkcs8EncryptedPem("myPassword")

    // You now have the private key in an encrypted format,
    // which may be (for example) saved to a database
