From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Note they're not encrypted. This is not safe. Dont do it.
Not by default, but yea it is encrypted, I use almost exclusively encrypted chats through TG, even my voice and video calls are encrypted through TG.
E2e encryption is security theater though, a chance for companies to tell states "We'D lOvE tO hAnD oVeR tHaT dAtA bUt ItS eNcYpTeD".
In reality, it doesn't matter, if someone wants to snoop on your convos you can't stop them.
Telegram desktop doesn't support e2ee
Android emulators exist on both windows and Linux allowing the android variant to run on desktop. With most modern machines this is a viable alternative to running natively, with some overhead of course.
Last time I tried that, they banned the telegram account.
Unfortunately companies like Telegram see emulators and they get false-positive banned by their fraud systems
Crypto works. Nobody can break good encryption.
You can make an argument for store now, break after quantum leap or whatever. But, no, if the US wants to spy on the communications of their enemies, they can't do it by breaking encryption.
Since you seem to understand it then:
How do two clients communicsting over a proprietary network negotiate an end to end encrypted chat channel without sharing keys in an easily decrypted manner?
It seems to me that some kind of handshake needs to occur where the clients need to agree on a cypher, so how does this happen securely?
I'm not worried about encryption being broken, it just seems like if you're handing the keys over the mail, it's pretty easy to xray the package and copy the key, is the same not true over digital communication?
This was a problem solved by Diffie and Hellman in the 1970s
