However, the majority of conversations on Telegram are not end-to-end encrypted, meaning administrators could access them if required by law enforcement. This poses risks for users discussing sensitive topics or sharing confidential information.
Moreover, Telegram’s encryption methods are seen as complex and opaque. For example, the optional Secret Chats use a proprietary encryption algorithm, which is difficult to verify and may include hidden vulnerabilities. Cryptography professionals have criticized this, noting that unless an encryption system is open-source, it cannot be thoroughly vetted for weaknesses or backdoors.
One of the significant drawbacks of Telegram’s security is its inapplicability to group chats. Group conversations cannot be encrypted, which increases the risk of unauthorized access to user messages.
For those needing strong privacy for sensitive communications, this is a serious limitation.
Given that other popular messaging platforms like Signal and WhatsApp offer end-to-end encryption by default, users of Telegram may want to reconsider using the app for private or sensitive discussions. Signal, for instance, uses the highly respected Signal Protocol, which has been audited and proven to be robust. Telegram, by comparison, leaves users with limited protection due to its closed-source encryption.
Despite these concerns, Telegram remains a popular app due to its versatile features, making it more than just a messaging platform. Telegram’s organizational tools, community management features, and ability to broadcast information have made it a favorite among certain groups, especially those sharing tech news or international updates.
However, for those who prioritize security, Telegram’s limited encryption may not be sufficient, making apps like Signal or even WhatsApp a safer option for encrypted messaging. While Telegram has many innovative features, its encryption limitations leave it far from being the most secure messaging app.
