A Secure Web-Based Android Chat Application Using The AES Encryption Algorithm

The major goal is to create an android chat application that allows numerous users to communicate securely. This is a cutting-edge encryption and decryption system that targets SMS for mobile Android users. The user has the ability to transmit encrypted messages and decrypt encrypted messages. The System uses the SMS that are visible in your inbox, but it filters out the encrypted SMS and displays them in your Personal Inbox in the Application. Only the user id, which is automatically encrypted in the message, has to be entered because the Shared Private Key is already established in the application. Therefore, anytime a user sends a message, he or she should be aware of the recipient’s ID since it is added to the message so that, if the intended recipient logs in, the message is already decrypted. The recipient’s id may only be saved in a separate column marked “Favorites” and contains the recipient’s id, name, and mobile number. The id is automatically created and cannot be modified. Given that a single user may have many accounts, logging in is required here’s with different ids so that he can maintain each account for various reasons without combining them. The communications are encrypted and decrypted by this system using the AES encryption algorithm. The front end of this app is Android Studio, while the back end is SQLite.
