114 Q: What are your thoughts on internet privacy? Q: What are your thoughts on internet privacy?
115 Big internet companies like Facebook or Google have effectively hijacked the privacy discourse in the recent years.

296 Q: What‘s this ’Encryption Key' thing? Q: What‘s this ’Encryption Key' thing?
297 When a secret chat is created, the participating devices exchange encryption keys using the so-called Diffie-Hellman key exchange . After the secure end-to-end connection has been established, we generate a picture that visualizes the encryption key for your chat. You can then compare this image with the one your friend has — if the two images are the same, you can be sure that the secret chat is secure, and no man-in-the-middle attack can succeed. When a secret chat is created, the participating devices exchange encryption keys using the so-called Diffie-Hellman key exchange . After the secure end-to-end connection has been established, we generate a picture that visualizes the encryption key for your chat. You can then compare this image with the one your friend has — if the two images are the same, you can be sure that the secret chat is secure, and no man-in-the-middle attack can succeed.
298 Newer versions of Telegram apps will show a larger picture along with a textual representation of the key (this is not the key itself, of course!) when both participants are using an updated app. Newer versions of Telegram apps will show a larger picture along with a textual representation of the key (this is not the key itself, of course!) when both participants are using an updated app.
299 Always compare visualizations using a channel that is known to be secure — it's safest if you do this in person, in an offline meeting with the conversation partner.

300 Q: Why not just make all chats ‘secret’? Q: Why not just make all chats ‘secret’?
301 All Telegram messages are always securely encrypted. Messages in Secret Chats use client-client encryption, while Cloud Chats use client-server/server-client encryption and are stored encrypted in the Telegram Cloud (more here ). This enables your cloud messages to be both secure and immediately accessible from any of your devices – even if you lose your device altogether. All Telegram messages are always securely encrypted.

This enables your cloud messages to be both secure and immediately accessible from any of your devices – even if you lose your device altogether.
302 The problem of restoring access to your chat history on a newly connected device (e.g. when you lose your phone) does not have an elegant solution in the end-to-end encryption paradigm. At the same time, reliable backups are an essential feature for any mass-market messenger. To solve this problem, some applications (like Whatsapp and Viber) allow unencrypted backups that put their users' privacy at risk – even if they do not enable backups themselves. Other apps ignore the need for backups altogether and fade into oblivion before ever reaching a million users.

Other apps ignore the need for backups altogether and fade into oblivion before ever reaching a million users.
303 We opted for a third approach by offering two distinct types of chats. Telegram disables default system backups and provides all users with an integrated security-focused backup solution in the form of Cloud Chats. Meanwhile, the separate entity of Secret Chats gives you full control over the data you do not want to be stored. We opted for a third approach by offering two distinct types of chats.

304 This allows Telegram to be widely adopted in broad circles, not just by activists and dissidents, so that the simple fact of using Telegram does not mark users as targets for heightened surveillance in certain countries. We are convinced that the separation of conversations into Cloud and Secret chats represents the most secure solution currently possible for a massively popular messaging application.Deeper questions This allows Telegram to be widely adopted in broad circles, not just by activists and dissidents, so that the simple fact of using Telegram does not mark users as targets for heightened surveillance in certain countries.
