In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats youβre having with folks are not as secure as you may believe. In a message on his Telegram channel recently recounting the episode, Durov wrote: "I lost my company and my home, but would do it again β without hesitation."
