• You don't have to when it comes to secret chats; simply make sure your secret chat's visualised key matches the one in your friend's secret chat settings.
• Telegramis open source, which means anyone can look at our source code, protocol, and API to see how it all works and make an informed decision. Telegram uses verifiable builds, which allow experts to independently verify that the code we publish on GitHub is the same code used to create the apps you download from the App Store or Google Play.
• Security specialists are free to audit our system, and we welcome any criticism at security@telegram.org.
• Furthermore, because Telegram's primary goal is not to make money, commercial interests will never get in the way of our purpose.
