I still stand with Signal App.

  • Telegram has no default E2EE.
  • Threema's encryption was compromised .
  • Threema & Telegram both are for profit companies.
  • Signal is non-profit & all their source code + finances are public. Even their server codes are publically available
[–] dukethorion@lemmy.world 2 points 4 months ago

Man, everyone is hopping on the Trash Signal Bandwagon, even though TG is less secure, and nobody (the 99%) uses Threema.

how has no one discussed matrix here

[–] dessalines@lemmy.ml 0 points 4 months ago (2 children)

I don't get it at all. There are plenty of platforms like matrix, xmpp, simplex that don't require phone numbers tied to your identity. Signal has somehow managed to convince people that it's a private platform, despite it being a US hosted service that requires phone numbers.

[–] drwho@beehaw.org 0 points 4 months ago (2 children)

It's a Google hosted service, which is arguably worse because they may as well be a nation-state unto themselves.

[–] refalo@programming.dev 0 points 4 months ago (1 children)

And the largest homeserver, matrix.org, is MITM'd by Crimeflare.

[–] msage@programming.dev 0 points 4 months ago (1 children)

Fuck matrix.org, just selfhost.

[–] drwho@beehaw.org 1 points 4 months ago

Doable, but a huge pain in the ass because of conflicts in the protocol. I spent about a year trying to suss them out and come up with a fix but never figured it out.

[–] EngineerGaming@feddit.nl 0 points 4 months ago (1 children)

Wasn't Amazon involved here as well? It is another "nation-state".

[–] drwho@beehaw.org 1 points 4 months ago

I do not think so, no. However, Amazon is certainly big enough to be un-humorously compared to nation-states as well.

[–] to55@discuss.tchncs.de 0 points 4 months ago (1 children)

Say the US government, in a worst-case scenario in which it constantly monitors all traffic that goes through Signal’s data centers, can ‘only' see phone numbers, IP addresses and timestamps, right? Or am I forgetting something here?

[–] dessalines@lemmy.ml 1 points 4 months ago* (last edited 4 months ago) (2 children)

Metadata and social graphs are more important than message content, esp since not many people have the time to read through individual messages to build meaning.

Signal stores phone numbers (meaning your identity, and home address), and message timestamps: who texted who and when, and who's in chats with who else. More than enough to build social graphs and connections, and also figure out where people are through their IP addresses.

[–] marcie@lemmy.ml 1 points 4 months ago (1 children)

Do you happen to know what metadata matrix stores? I assume matrix.org specifically stores email and username, right

[–] dessalines@lemmy.ml 1 points 4 months ago

Yes, but I don't think user metadata outside of your apub url, name, icon, display name, leaves your homeserver. Email or passwords don't leave iirc.

[–] brayd@discuss.tchncs.de 0 points 4 months ago (1 children)

Signal can't see who is texting who. They can't see which groups you are part of. Those information are end to end encrypted, same as your chats itself, your profile picture, your stories, etc.

Signal doesn't store message timestamps either.

What Signal itself knows of you is your phone number, the timestamp of your registration, the timestamp of your last connection to the server. That's it.

Yes metadata is critical but Signal handles metadata very well. Indeed, even though I'm a fan of Matrix, better than Matrix. Matrix is a metadata nightmare due to it's centralized structure and the way the protocol works.

[–] dessalines@lemmy.ml 1 points 4 months ago

Signal can't see who is texting who. They can't see which groups you are part of. Those information are end to end encrypted, same as your chats itself, your profile picture, your stories, etc.

This is completely false. They can absolutely see who is texting who, in fact they need it to be able to route messages. They have message timestamps, and phone numbers stored in their database.

Question, why do you "trust" signal? You can't see what code their centralized server is running, unlike matrix which you can self-host and build from source. You don't have to "trust" matrix, you can verify it for yourself.

I can't believe people are saying Telegram and Threema might be better than Signal. Signal isn't perfect but Telegram and Threema are worse.

[–] hruzgar@feddit.de -1 points 4 months ago (1 children)

Signal is much worse than Telegram (in terms of privacy)

[–] refalo@programming.dev 0 points 4 months ago (1 children)

Please give several reasons why

[–] hruzgar@feddit.de 1 points 4 months ago* (last edited 4 months ago) (1 children)
  1. The Encryption algorithm of Signal is basically the same algorithms proposed by the US gov in 2000. There is no way they would release these encryption algorithms if they couldn't break them themsleves
  2. If you would see which organisations are supporting Signal (look at where Signal gets all the money), you would also agree with me. There is no way these organasations are supporting them for your privacy. Why would they? The same people who are trying their best to get all your data. Believing this is just pure naivity imo but call me what you want
[–] refalo@programming.dev -1 points 4 months ago (1 children)

Please stop spreading FUD.

  1. The encryption used by Signal would not be used if it could be easily broken. It's fully open source and is regularly audited. People would not recommend it if it were so broken like you say; this is just fearmongering.

  2. lol, lmao even

[–] hruzgar@feddit.de 0 points 4 months ago

I'm not forcing you to believe anything. Also this is a free platform where I can say what I think. I won't hold myself back from expressing my view only because the majority has a different opinikn (looking at the downvotes). I personally just wouldn't trust it. And it also doesn't have any difference to Whatsapp and co. (encryprion algos are the same) which completely removes the purpose of it even existing (ik open source is still an argument. But they don't have reproducable builds so even that falls apart) so there really isn't any reason for me to switch to it or promote it to anybody at all.

[–] boerbiet@feddit.nl -1 points 4 months ago

It really depends on your use case. Most of my simple chat messages are the same as I would have in any public space. I have no need for encryption, I have need for convenience in that regard. With Telegram I have my chat history on all devices and don't need to use my phone to connect which are two must-haves for me. For my use case, Signal is the worse option. That doesn't make Signal bad, just not suitable for me.

As a privacy-concious person I am very much aware of the non-secure nature of my chats, but since that is not a factor of consideration to me when it comes to casual chats with a few friends and family members. The worst thing Telegram could do is analyse my chats and ... then what?

[–] rdri@lemmy.world -2 points 4 months ago (3 children)

Signal is not applicable when you need a public space for people to just have a discussion, like in discord. Signal clients are clunky and rely on cross sync from what I see, while telegram clients are well made and convenient to use. Even Whatsapp went away from electron so I'd choose it over signal any day.

[–] refalo@programming.dev 0 points 4 months ago (1 children)

Signal clients are clunky

Obviously you have never used Element for matrix. Signal is like a Ferrari in comparison.

[–] rdri@lemmy.world -1 points 4 months ago

Yeah I've never used matrix really.

[–] kilgore_trout@feddit.it 0 points 4 months ago (1 children)

Have you tried Signal recently? On Android it's very well polished.

In fact I believe it's a shame that not more people use such a beautiful app, regardless of privacy and security implications.

[–] rdri@lemmy.world -1 points 4 months ago

I have no use for it for now and as long as it's still electron on desktop I don't want to have it running.

[–] possiblylinux127@lemmy.zip 0 points 4 months ago (1 children)

Matrix would work for that and would avoid proprietary software and sketchy companies

[–] rdri@lemmy.world -1 points 4 months ago

Does it sync automatically between desktop and mobile? Can I share an image into it on mobile and have it a few seconds later on laptop?

[–] JustMarkov@lemmy.ml 0 points 4 months ago* (last edited 4 months ago) (1 children)

Let's be honest, Signal is not perfect either:

  • It requires your phone number
  • It has had some suspicious funding sources
    (UPD: It was funded by CIA)
    (UPD2: Here I will quote www.securemessagingapps.com:

This matters because “money talks”, as the saying goes. If the company or person behind the money is likely to have reason not to protect customers’ privacy, it’s important to know. This could be indicative of the company not doing as they say (Google, Whatsapp, for example) or changing their mind once they’ve onboarded enough customers from whom they can make money.

~~(I'm gonna find sources for the last two statements a bit later to not be unsubstantiated)~~
Done.

Although, we all can agree, that Signal is still better than Telegram, or WhatsApp, or Threema, or whatever.
Still, we probably want to look at the better alternatives, like Simplex or Session.

suspicious funding

Which lines of its libre software source code are malicious?

requires your phone number

It's centralised

[–] JustMarkov@lemmy.ml 0 points 4 months ago (1 children)

Which lines of its libre software source code are malicious?

It's not about code, but about funding.

It's centralised

Yes, and it's the downside, no matter how you look at it.

[–] autonomoususer@lemmy.world -1 points 4 months ago* (last edited 4 months ago) (1 children)

So, which malicious lines of libre software source code have been funded? This is how we stop FUD. Don't let them derail us.

[–] JustMarkov@lemmy.ml 0 points 4 months ago (1 children)

Don't get me wrong. As far as we know, no malicious code have been funded. The very fact that the Signal was sponsored by the CIA is suspicious (maybe I used some incorrect words, sorry if so). Of course, it's totally up to you whether you think that fact is sus or not.

[–] autonomoususer@lemmy.world -1 points 4 months ago

It's not. Our devices run software, not funding.

[–] quantenzitrone@feddit.de -1 points 4 months ago

Signal is currently the best middleground between security, simplicity and widespread adoption.
