Questions tagged [mtproto]

The protocol is designed for access to a server API from applications running on mobile devices. It must be emphasized that a web browser is not such an application.

The protocol is subdivided into three virtually independent components:

  • High-level component (API query language): defines the method whereby API queries and responses are converted to binary messages.
  • Cryptographic (authorization) layer: defines the method by which messages are encrypted prior to being transmitted through the transport protocol.
  • Transport component: defines the method for the client and the server to transmit messages over some other existing network protocol (such as, http, https, tcp, udp).
