Every text you send through Telegram is stored in plaintext. Telegram and authorities can access that without your knowledge. Also it will get leaked in a breach someday.
Now you decide for yourself if it's private.
False. If you want to tell how things works, get your facts right!
All data sent to Telegram's servers will be encrypted once they reach the servers. With other words, the messages and media and other files, will be sent in "plain text" over HTTPS only when using Cloud Chat. In Secret Chat, MTProto is (based on how E2EE works) as safe as what Signal Protocol is.
But nothing will be stored in plain text, no matter what you use (Cloud Chat or Secret Chat).
But(!) since the source code for MTProto is closed, we don't know how it really works, and if we can trust their FAQ or not.
I trusted Telegram at first, but I don't trust it 100% anymore (still better than SMS). Am using my own Snikket server these days. Much safer with a lot of ππππ moments, even today, maybe a year later. Especially with OMEMO (Signal Protocol).
and who generated the key?
After doing a quick scan of their FAQ, there's nothing about who generated the key. So my wild guess is the client. I bet their source code can answer that question, but I have no clue.
That was a rhetorical qustion. It's their servers which generates the key. So Telegram has both the lock and the key and claim they are "heavily encrypted".
