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.

"Your messages about the movement of the enemy through the official chatbot … bring new trophies every day," the government agency tweeted.
