MTProto
MTProto is a proprietary protocol developed by Telegram for secure client-server communication, primarily used in its messaging app. It operates on top of TCP/IP and employs a combination of symmetric and asymmetric cryptography to ensure data confidentiality and integrity. The protocol is designed for high performance and reliability, supporting features like end-to-end encryption in secret chats and cloud-based messaging.
Developers should learn MTProto when building or integrating with Telegram's ecosystem, such as creating bots, custom clients, or third-party services that interact with Telegram's API. It is essential for implementing secure communication channels in applications that require Telegram's specific encryption standards or for those working on privacy-focused messaging platforms that study its design. Use cases include developing Telegram bots for automation, building alternative Telegram clients, or researching secure messaging protocols.
