    // Generate a 1024-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 4096 bits.
    // Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.
    // It takes a considerable amount of time and processing power to generate
    // an 8192-bit key.

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

    var privateKey: String? = rsa.exportPrivateKey()
    print("\(privateKey!)")
