Telegram appeared in 2013. Many countries, Hong Kong, Azerbaijan, Belarus, temporarily blocked access to Telegram, China completely banned the messenger on its territory. The reason for this reaction to the channel was the complete confidentiality of users. The chat management does not cooperate in providing access to correspondence if it believes that the claims against group members are not justified.
Для большей безопасности и анонимности в 2017 г. IT-специалисты оптимизировали возможность подключения к мессенджеру через прокси-серверы протоколов HTTP(S) и Socks. В связи с тем, что прокси часто блокируются службами мониторинга сайтов, владельцы канала создали свою технологию защиты — MTProto (Messaging Telegram Protocol).
MTProto is a cryptographic encryption protocol used for correspondence between devices.
Features of the MTProto protocol
- When connecting, it does not use authentication (login and password), only a password (secret key) is enough
- Traffic is the same as regular HTTPS/TLS
- When connecting, the password is not transmitted to the server. Lack of open exchange of information between the user and the server.
- It only works in the Telegram system; this proxy cannot be connected to other applications.
- Works anonymously, does not reveal its presence
- Using Promoted channels makes it possible to monetize your personal MTProxy
Difference between MTProto and other protocols
MTProto protocol when connecting, it does not send a request for permission to transmit a response to Telegram servers, as other protocols do. The application considers it a messenger server, so it automatically provides access to the system.
How the MTProto protocol works
Data transfer occurs using obfuscation (obfuscation: changing the form, appearance, recording without changing the functional significance of the code). It confuses the codes so that it is impossible to analyze them. The information is encrypted with a key and a “secret”, the latter is adjusted to the messenger at the time the MTP proxy is connected. The “secret” (a code generated individually for each person) cannot be detected when exchanging messages. Cryptographic protocol MTProto provides guaranteed security when communicating in Telegram and protects users and group members from interception of information by third parties.
The table presents the advantages and disadvantages of the MTProto protocol.
| Advantages | Flaws |
| The protocol completely encrypts user information. No provider can track the user’s body movements in the application. | Due to the decryption and encryption of packets, the data transfer rate is lower than other servers. |
| The protocol is free | You cannot make calls when connected to MTProto |
| You can attach several MTProxy to one subscriber | Used only in the mobile application |
Alternatives to proxy servers for working in Telegram
You can also use one of the alternative solutions that will help you gain access to the messenger.
- Anonymizers. A tool that helps encrypt all incoming and outgoing information. This tool will help you gain access to most of the prohibited resources. Anonymizers can also be flexibly configured for specific user tasks.
- VPN is a well-known proxy alternative that helps establish an anonymous Internet connection in the browser.
From all of the above, one thing is clear: Telegram takes care of its subscribers, ensuring their safety. The messenger team does not stand still and is developing new opportunities to realize the potential of users. In addition, developed by Durov MTProto serves developers of other sites and helps make Internet resources anonymous. The source code is publicly available, so anyone can use it.
