The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. Save Messages You Want to Access Anywhere Telegram offers a few other handy options in chats. You can delete any message by long-pressing it, then hitting the Trash icon that appears. The app lets you delete messages at any time—even messages that the other person sent in a chat.
Telegram Attachment Options New icons are available that premium users can add to their Home Screen to better match their personality or wallpaper. Choose from a premium star, night sky, or turbo-plane. On the same page, Telegram also lists one of its two tenets of internet privacy as “protecting your personal data from third parties, such as marketers, advertisers, etc.” That puts it in stark contrast to a myriad of services from Facebook, Google, Amazon, and others. To create a poll in a channel or group, simply select the “Poll” option in the attachment menu. Type in your question, add answer options and choose the configurations that fit your purpose best.
Security There are thousands of bots available on Telegram. We've sorted through them and picked out the best Telegram bots you should use. If you are a group admin on Telegram, Slow Mode is what you need to stop unnecessary spam and make the conversation more orderly. After you turn on the slow mode and choose the time interval, group members will have a restriction to send one message in the defined interval. Say, for instance, if you choose the time interval to be 15 seconds, after sending one message, the group member will have to wait 15 seconds to send another message. It will definitely raise the value of each member and individual messages. You can turn on Slow Mode by tapping on the Group name -> Edit (pen icon) -> Permissions -> Slow Mode. Telegram allows users to locate contacts nearby you, should they choose to be discovered. This allows you to quickly add someone close to you on Telegram without going through the hassle of first noting their number and saving the contact manually. Users can also use this feature to find and create groups of nearby users.
To lock a chat go to Settings->Privacy and Security->Passcode Lock and enable it. Once you create a passcode and enable it, you will be able to lock and unlock your chats by tapping on the lock icon at the top right of the app. After that, hit the More button (triple-dot icon) and choose Enable Auto-Delete in the popup menu. Next, choose the desired period of time like 1 day, 1 week, or 1 month. If you would rather want to go with a custom period of time, tap Other and then adjust the time.
