Short Message Service (SMS) is a comprehensive mobile phone service for users to communicate with others, a faster and more convenient way of communication. However, it has some limitations such as: the inability to search and categorize SMS and there is room for improvement, thereby solving real-time text messaging problems. Our system provides basic text messaging functionality as well as various features such as categorizing messages based on personal, social, transactional, and custom categories with colour codes within the app, bill due date reminders, and highlighted messages. Encryption is paramount when sensitive data is transmitted over the network. Various encryption algorithms such as AES, DES, RC4, and others are available for this. The most widely used algorithm is the AES algorithm. We have developed an application on the Android platform that allows the user to encrypt messages before they are transmitted over the network. We used the Advanced Encryption Standards algorithm for data encryption and decryption. This app can run on any device with the Android platform. This application provides safe, fast, and strong encryption of data. A large amount of data confusion and proliferation occurs during encryption, making it very difficult for an attacker to interpret the encryption pattern and the plaintext form of the encrypted data.
