Many in the crypto and privacy community mistakenly trust Telegram because it's "end to end encrypted", but there are huge issues including not hiding the metadata, censorship, centralization, and phone numbers.

You shouldn’t trust anything.

[–] [email protected] 8 points 1 year ago

I trust myself sometimes, its occasionally useful.

[–] [email protected] 2 points 1 year ago

Can't trust nobody and nothing.

Can we stop doing videos as news and opinion please? They're an inefficient, annoying, and intrusive way to communicate this kind of information. If it doesn't need to be visual, it is in video format only for monetization reasons, which I'd think would be more concerning to this community.

[–] [email protected] 23 points 1 year ago (1 children)

Videos are also much more likely to be out of date.

Wow, not to pick on the narrator, but this comes off like the worst small town used car dealership TV advertisement I've ever seen.

Here's a real rundown I've put together over the years:

Pavel Durov's argument is that there should be a high functioning UI/UX experience for "non-secure" communication, and when you need it there's something much closer to Signal's very secure client-to-client encryption.

Arguably Telegram secret chats are even "close enough" to cloud chats an adversary might not notice you're doing the "super secret things" (making it harder to identify what to target).

MTProto Cloud: https://core.telegram.org/file/811140746/2/CzMyJPVnPo8.81605/c2310d6ede1a5e220f

MTProto Secret (Wrapped in MTProto Cloud): https://core.telegram.org/file/811140633/4/hHw6Zy2DPyQ.109500/cabc10049a7190694f

They also provide verified builds even on iOS (though it's a bit of a hack, not "really" quite the same thing).

The only things that can really be said about Telegram's secret chat crypto are that:

  1. It's not "the default"
  2. It's their own crypto (i.e., they broke "rule #1" and "rolled their own")

Ultimately though, it's been just shy of 10 years since Telegram entered the scene, and nobody has actually broken Telegram crypto in any meaningful way -- AFAIK, to this day. Still, there are hypothetical holes in the crypto when scrutinized vs something like signal. So, is it as good as Signal or Threema? Eh, probably not, is it good enough for the average person that isn't target by a nation state? I'd say probably.

Isn't metadata leakage a problem that this messenger shares with nearly every other (popular) messenger out there?

In case you actually want some useful info on that topic: https://www.messenger-matrix.de/

Nice comparison site! I've always referenced the below site. But I'm glad to have another thank you

That's a cool website!

[–] [email protected] 24 points 1 year ago (5 children)

Stop posting videos and post well written articles.

Thats why Element(Matrix) is the way. Ideally selfhosted+federated, but even the default matrix.org is much better than most other chat apps.

[–] [email protected] 4 points 1 year ago (1 children)

Why Matrix and not XMPP? XMPP is also flawed, but much less bloated, easier to selfhost and doesn't have so many people being on central instance like matrix.org (there are other arguments as well).

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (1 children)

Because there's not a single good app for XMPP and nobody uses it.

Their bleeding edge app is Conversations which costs money (already unviable), and the app looks like it's designed in 2012.

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago)

It does NOT cost money on F-Droid. You don't even need to install the market itself, you can get the app from F-Droid's website (though then you'd have to check for updates yourself). For me, it was a chance to get mom to F-droid.

[–] [email protected] 4 points 1 year ago

It may be once sliding sync and proper key handling of room history for new members get implemented.

Right now sync is very slow, the apps are heavy weight too (as I know at least partly because of how sync works today), and if a new member joins an encrypted room, they will not see the history even if you set it that way, because the clients that know the keys won't send to theirs.

[–] [email protected] 9 points 1 year ago

The only reason telegram was unbanned in Russia is because they started collecting and handing over identifiable data about Russian users.

[–] [email protected] 9 points 1 year ago (2 children)

The only thing Telegram has going for itself is that it's Non-Meta and Non-Western.

Anyone who has a closer look at Telegram's reputation knows that their privacy claims are dubious. If you want end to end encryption, even WhatsApp is better. But these things depend on your individual threat model.

[–] [email protected] 12 points 1 year ago (1 children)

If you want end to end encryption

You use Signal.

[–] [email protected] 9 points 1 year ago (2 children)

Yeah, end to end encryption in a closed source app can't be proven outside of the company and the company can't be held accountable by the public even if it gets a third party audit at some point because it can always just change the source.

Open source, client side, end to end encryption is the only serious standard.

Telegram can be E2E, no reason to switch to Meta's app for it

[–] [email protected] 5 points 1 year ago

I try to explain that to people all the time, they only use E2E for so called secret chats and comply with every country as soon as a ban is on the table, there are even reports about a case in Dheli where they did so for Audiobook piracy!

[–] [email protected] 5 points 1 year ago (1 children)

Who thinks in the privacy community that Telegram is end to end encrypted? They were largely mislead. That's an option, that even prevents sync of the chat between your devices.

The thing is, Telegram has some shady things, but until Matrix becomes usable this is one of the very few usable options. And until then, use Telegram FOSS from F-droid.

  • Huge resource usage by clients
  • Huge sync times (not just first time, but also if the client was offline for a few weeks)
  • New room members in encrypted rooms can't read old messages even if you have set it up that way

Fortunately they are working on all of these, and as I just found out recently, they also have an alpha version app now that makes use of the new efficient sync, which I expect to fix 2 of the above (the resource usage is partly because of how sync works now)

Why isn't this video uploaded to peertube instead of some dude's personal bog?

[–] [email protected] 10 points 1 year ago

Because its just that. All it is a personal blog. It is not a valid source

[–] [email protected] 4 points 1 year ago

I like mixing it up, even mid conversation, between Threema, Signal and Session. Put the puzzle together feds xD

[–] [email protected] 2 points 1 year ago

Indeed it is. Use Threema 😉
