Why bother if you can make all chats equally safe without discombobulating the user? But Telegram is one of a kind. The user doesn’t need to do anything at all, there are no special checkboxes or anything: messages are protected from all outsiders (including the service owners) right out of the box.Īs for messengers that explicitly position themselves as secure and protected, no one at Signal or Threema would ever think of having two types of correspondence: one end-to-end encrypted, one not. No other messenger does this: even the notorious WhatsApp, part of Mark Zuckerberg’s data-hungry empire, uses end-to-end encryption by default. Regular chats are not end-to-end encrypted. Let’s go straight to the root of the problem: Telegram is a unique messenger with two types of chats: regular and secret. Not all Telegram chats are equally secure Now let’s see how Telegram handles all this.
So, we arrive at a very simple formula: a secure messenger is one that uses end-to-end encryption.
This automatically protects correspondence from nosy owners (current or future) and from the other troubles that might occur. As such, the service sends back and forth only encrypted messages and does not have access to the content. This ensures that information is encrypted on the sender’s device and decrypted only on the recipient’s device. However, there’s a very effective way to avoid all these dangers and answer the question of whether the service can be trusted once and for all: end-to-end encryption. Or, even if we assume they’re honest to the core and have no desire to stick their noses into users’ data, where’s the guarantee that, if the service is one day sold, the next owners would be as honest? And then of course the service could get hacked, in which case the hackers themselves would gain access to correspondence. For example, the owners of the service themselves may turn out to be overly curious or greedy. Here’s why: if not only messaging participants but also the service has access to chats, then that creates additional risks. However, that’s not enough to consider a system secure, since it does not guarantee total message security. That’s the absolute minimum that any messenger should provide. The first thing to realize is that almost all modern messengers long ago switched to encrypted data exchange between user devices and servers. To start with, let’s figure out how a secure messenger works. Let’s take a look at some rather dubious features in both the messenger’s interface and general logic that make it less secure than is commonly believed. But in practice that’s not entirely true: the reality is that Telegram has a number of quirks that make protecting your messages a little tricky, and it’s got nothing to do with the complexities of cryptography, but with much more prosaic stuff. Telegram’s developers position their product as safe and protected.
