Security The chat uses its own TCP protocol based on end-to-end encryption in conjunction with the Diffie-Hellman and ChaCha20-Poly1305 algorithms. The keys are generated each time the server is accessed, which makes it impossible to decrypt intercepted messages. The mode of safe viewing of links received in messages from other users eliminates the possibility of phishing and tracking. This mode allows you to completely disable the operation of software scripts, navigation, downloading of any files. A minimum set of resources, such as photographs, style remains and can be downloaded via proxy if desired, which eliminates the recording of a real IP address. At the same time, it is also possible to open the link in normal mode. Monitoring of system information, such as processor load, memory consumption and temperature will allow you to record abnormal behavior of the system and, if desired, enable blocking mode in case of suspected cyber attack. Minimalism and simplicity The chat is designed as simply and ascetically as possible. The interface will help even an inexperienced user to understand it. All unnecessary functions are excluded and the emphasis is placed exclusively on the main concept of the application - communication and security. Selective caching allows you to speed up loading, but without filling the local memory of the device excessively. Monitoring network connections will allow you to adapt for loading even in case of weak network signals. Low power consumption A simplified model allows you to reduce energy consumption resources when using the application. Also, computing processes are minimized, which prevents heating of the device. Background processes handle only network data exchange and do not include graphic tasks that are not used in this project. Animation and resource-intensive visual effects are also minimized.
