Telegram supports two layers of secure encryption. Cloud Chats use server-client encryption while Secret Chats use an additional layer of client-client encryption. All content is encrypted in the same way — be it media, text, or files. Auto-download and Auto-play Media Premium app icons

Most people use third-party apps to make sure that no one gets a hand on their private conversations. Telegram, however, has its own lock function to hide privates messages behind a passcode. Just like we can share videos with a pre-defined timestamp of YouTube videos, we can do the same thing on Telegram as well. For example, if you are sending a long video and want the user to play it from a specific timestamp say, 1:20, you can just type check the reaction at 1:20 in the video caption. Now when the user taps on the highlighted 1:20 link, the video plays from that particular timestamp. This is a helpful tip for users who send videos on Telegram regularly. The platform supports two types of channels: public and private. The former can be found in search, and anyone can join them, whereas the latter can be joined only via invitation links.

Edit Photos/Videos Before Sending Them Security The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. If you don’t want to go through the hassle of customizing your own theme and still want to theme your Telegram, you can do that too. To do that, tap on the search icon and search for the word Themes. In the results, tap on Android Themes Channel. The channel houses the list of all the themes that people create and share. Just scroll to find the one you like. Once you find a theme that you like, tap on the download icon. Once it’s downloaded, tap on it again and then tap on the Apply button.

Because Telegram lets you interact with people even if you aren't in each other's contacts, you may wish to make your account more private. To change privacy options, head to Settings > Privacy and Security. Here, you can change who can see your phone number, active status, and more. Perhaps the most important and the best feature of the Telegram app is its security. It is based on the MTProto protocol that is built upon time-tested algorithms. It enables high-speed, reliable message delivery on weak connections.
