SicherChat vs X2Chat

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.

X2Chat - Secure Messenger Built for Privacy X2Chat is a modern, privacy-first messenger that puts you in control of your data. Every message, file, and call is protected with end-to-end encryption. No one in the middle - not us, not your provider - can read your conversations. END-TO-END ENCRYPTION - RSA-2048 for session key exchange - AES-256-GCM for content (text, files, media) - WebRTC Insertable Streams for calls - true E2E at the RTP-frame level - Trusted-key QR codes - MITM protection from the server itself CALLS FAST AND CLEAR - High-quality 1-on-1 and group audio/video calls - Ultra-low latency through an optimized audio pipeline - Native CallKit integration - lock-screen calls feel like system calls - Adaptive bitrate and resilience on weak networks CLOUD BACKUP WITHOUT COMPROMISE - Encrypted backup secured with your own password - Account restore on a new device via slot_id and password - iCloud Keychain sync for seamless device migration PRIVACY BY DEFAULT - Zero ads, zero tracking - Minimal metadata stored server-side - Open encryption architecture X2Chat fits private conversations, work communications, and everything that should stay strictly between you and your contact.
