What Is Telegram?


Telegram is a free cross-platform instant messaging application that allows users to send text, images, videos, audio, and files, among other types of messages. Telegram also supports group chats, voice calls, and video calls. One distinctive feature of Telegram is its "Secret Chat" option, which employs end-to-end encryption, meaning only the participants can read the messages, and Telegram servers or third parties cannot access them.


Is Telegram Encrypted?


Telegram uses different encryption methods depending on the chat mode: regular chats and Secret Chats. Regular chats are the default chat mode and employ a custom encryption protocol called MTProto. While this protocol is considered secure from a technical standpoint, it has faced criticism from some experts for not undergoing thorough review and testing. Messages from regular chats are stored on Telegram's cloud servers, which means Telegram can access these messages and may be compelled to hand them over under legal or governmental pressure.


Secret Chats, on the other hand, use a widely recognized end-to-end encryption protocol. This protocol ensures that only the participants can decrypt the messages, and neither Telegram nor any third party can eavesdrop. Messages in Secret Chats are not stored on Telegram's servers; they exist only on the participants' devices. Secret Chats also support self-destructing messages, allowing users to set a timer for automatic message deletion.


What Security Issues Does Telegram Face?


Despite offering a degree of encryption and privacy protection, Telegram still faces some security issues, such as:

① Limited Encryption in Regular Chats

Regular chats lack end-to-end encryption and can sync across multiple devices. This means that if your device is lost, stolen, or if you forget to log out from other devices, your regular chat history may be viewed or compromised by others.

② Inconvenient Secret Chats

While Secret Chats provide end-to-end encryption, they require users to manually initiate them and are limited to communication between two devices. This means that if you want to have Secret Chats with multiple people, you need to create separate Secret Chats for each person, and you cannot switch between different devices.

③ Protocol Imperfections

Telegram's encryption protocol is not without its flaws or weaknesses. For instance, in 2016, an Iranian hacker claimed to be able to obtain Telegram users' phone numbers and contact lists by cracking the MTProto protocol.

④ Government or Organizational Surveillance, Censorship, or Interference

Telegram's servers are not entirely under user control but are managed and operated by Telegram itself. This means Telegram may be subject to surveillance, censorship, or interference from governments or other organizations. For example, in 2018, the Russian government attempted to block Telegram and requested user data and decryption keys. Telegram refused, but it led to disruptions and instability in Telegram's services in Russia.
