Telegram | DID YOU KNOW?
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. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so.
