Nearly, all these apps have various built-in features that attract users, but most of the time, the app developers overlook the security aspect of their usage. To make data transmission between sender and recipient safer. A mobile application is going to build which will provide a protected private platform for users. In the application, an encryption layer adds for secure communication between two users. The applications start delivering messages through the internet, which is free for users. Any type of message can be sent, including text messages and voice messages. When evaluating the quality of mobile applications, security is one of the most crucial factors. The aim is to develop a fully secure messenger that provides a secure platform to the user in which the focus is to provide end-to-end encryption. Also, use suitable libraries for encryption. After communication, if the user updates the keypair the previous chat will be deleted automatically and there is an essential feature that when the user sends voice messages and photos it will show only once while the chat is open when the chat is closed voice messages and photos are deleted automatically. Also, one of the important features of the application is that screenshots could not be taken it is prohibited due to security reasons.
