Assume you are a city bicycle rental company. The bike lock is equipped with a cryptographic system that people must open through the app. An applet is received by scanning a QR Code on the bike. The authenticity of the applet and access to your company's service is confirmed through the Internet. The user will be able to purchase your service using this app. Typically, a bike ride from your company for a few hours. With the implementation of this applet and user authentication, a contract between the parties has been created.

You intend to create a dedicated encrypted connection between yourself and your friends. You can design an applet that encrypts your conversations through an algorithm and secure key, and exchanges message through a cloud server. You and your friend are the only secure key holders. In this situation, you can design an applet with a different algorithm and function each time you want and send it to your friend through social networks or any other way.
