Secret Telegram Messenger
Q: How are Secret Telegram Messenger different?
Secret Telegram Messenger are meant for people who want more secrecy than the average fella. All messages in Secret Telegram Messenger use end-to-end encryption. This means only you and the recipient can read those messages — nobody else can decipher them, including us here at Telegram. On top of this, Messages cannot be forwarded from Secret Telegram Messenger. And when you delete messages on your side of the conversation, the app on the other side of the Secret Telegram Messenger will be ordered to delete them as well.
You can order your messages, photos, videos and files to self-destruct in a set amount of time after they have been read or opened by the recipient. The message will then disappear from both your and your friend's devices.
All secret chats in Telegram are device-specific and are not part of the Telegram cloud. This means you can only access messages in a secret chat from their device of origin. They are safe for as long as your device is safe in your pocket.
Q: How do I start a secret chat?
Android: Swipe right to open the menu, then ‘New secret chat’.
WP: Tap + in the chats list, then ‘New secret chat’.
Remember that Telegram secret chats are device-specific. If you start a secret chat with a friend on one of your devices, this chat will only be available on that device. If you log out, you will lose all your secret chats. You can create as many different secret chats with the same contact as you like.
Q: How do self-destructing messages work?
The Self-Destruct Timer is available for Secret Chats only. To set the timer, simply tap the clock icon (in the input field on iOS, top bar on Android, chat info page on WP), and then Set Self-Destruct Timer to the desired time limit. The clock starts ticking the moment the message is displayed on the recipient's screen (gets two green checks). As soon as the time runs out, the message disappears from both devices.
Photos sent with short self-destruct timers (< 1 minute) can only be viewed while you're holding your finger on them — and we will try to send a notification whenever a screenshot is taken.
Please note that the timer only applies to messages that were sent after the timer was set. It has no effect on earlier messages.
Q: What‘s this ’Encryption Key' thing?
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.
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.
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.
Q: Why not just make all chats ‘secret’?
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 This enables your cloud messages to be both secure and immediately accessible from any of your devices – even if you lose your device altogether.
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.
