And this is how you can tell that Signal is legit.

Do you really need a better endorsement?

Really? its about the only quality messaging tool if you actually care about privacy. Other apps that claim to be e2e encrypted tend to leave themselves little loopholes in that claim. You think WhatsApp doesnt have the keys to your messages and wont hand them over to the government when asked? Think again. On Signal the only people with the encryption keys to your messages are you and the recipient.

Signal doesnt fuck around with Law Enforcement:

You forgot to mention the most important part:

Signal is made by a NONPROFIT organization. It does not gain any advantage by selling your data (which it doesn't do unlike Whatsapp etc)

Both Swedish government officials and now the Swedish defence force use it officially since it's so secure!

I'm sure there are other examples out there.

And the people in charge of it actually seem to not be huge assholes or shady weirdos. I listened to a 2 hour interview with Meredith Whittaker and she's like super smart and seems like a really decent person who has the right priorities. I hope it stays this way, but right now the whole thing really seems to be an awesome project with people in charge who actually know what they're doing and who are not interested in selling or otherwise misusing your data.

Nonprofit doesn’t mean can’t make a profit, it limits use of said profit into going back to the cause. That’s why plenty of non profits jealously guard their IP donations, that massive funding source runs a lot of their programs.

So, merely being a non profit doesn’t mean they won’t be willing to sell. This isn’t a negative to them, more a “that branding is not fully trustworthy on its own, verify” warning.

Huh? Signal was made by an American company, by Americans, in America. Not sure why you're bringing up Europe or its regulations. Regulations which are frequently anti-privacy, btw. https://x.com/mer__edith/status/1796508893822238881

Maybe you're thinking about Session, a similar privacy focused messenger which is run by a Swiss group?

You think WhatsApp doesnt have the keys to your messages and wont hand them over to the government when asked? Think again.

I dislike WhatsApp, too, and much prefer Signal, but this is a straight up falsehood.

WhatsApp literally uses the Signal protocol, including the key generation and handshake parts:

https://signal.org/blog/whatsapp-complete/

WhatsApp is basically a wrapper around Signal at this point and the big difference is that Meta has access to a lot more metadata.

u/hughk Feb 17 '25

It does but there are issues around key handling. This is particularly in relationship to group chats.

u/ohz0pants Feb 17 '25

Very good to know!

u/hughk Feb 18 '25

It is easy to find good encryption algorithms already coded. The weak parts are usually key generation and management.

u/ohz0pants Feb 17 '25

Yes. Hence my comment about having access to more metadata.

But they cannot read the content of the messages or provide the keys to anybody because they never have them.

We can be critical of WhatsApp and Meta without resorting to lies about their access to the encryption keys.

Using any E2E platform, even WhatsApp, is still way, way better than plaintext SMS, or tweets, or facebook messages, or discord, or telegram, or whatever else.

u/countzer01nterrupt Feb 17 '25

Regardless, if you can - use signal, donate a few bucks to them and don't trust meta.

I suppose they mean that when you report someone in whatsapp, recent messages are forwarded as part of the report, as otherwise they'd not be able to tell what your report is about or whether it's a false claim. They say what's happening here https://faq.whatsapp.com/1142481766359885?cms_platform=web#report-someone. You trigger the app to send them proof.

Report someone
WhatsApp receives the last five messages sent to you by the reported sender or group, and they won’t be notified. WhatsApp also receives:
The reported group or user ID.
Information about when the message was sent, and the type of message sent such as an image, video, or text.

Not an issue or "hole". The argument along the lines of "build it yourself or it cannot be secure" imo isn't sane as it requires some arbitrarily drawn line under realistic circumstances - the boundary is human trust based on incomplete information.

Do you trust them 100% to never upload your private key to their server, or do it in the future?

u/No_Nose2819 Feb 17 '25

What’s App constantly nags you to save all your messages to the cloud so the NSA can read them in real time though.

u/ohz0pants Feb 17 '25

Backups can be encrypted.

https://blog.whatsapp.com/end-to-end-encrypted-backups-on-whatsapp

You can now secure your end-to-end encrypted backup with either a password of your choice or a 64-digit encryption key that only you know. Neither WhatsApp nor your backup service provider will be able to read your backups or access the key required to unlock it.

Messenger supports E2EE using Signal but it's not on by default for group chats IIRC.

u/unbanned_lol Feb 17 '25

I'm not claiming that this is what happens, but as a developer, if you write a wrapper around another piece of software, you have every chance of siphoning off data in the wrapper.

Put another way: it doesn't matter if a message can go from A to B without being read if you have someone looking over your shoulder at points A and B.

u/tempest_ Feb 17 '25

Yeah, WhatsApp (meta) controls both sides of the communication unless you know exactly what that app is doing. If they are decrypted on one end to show you the message Meta can get access to it.

u/JelloOverall8542 Feb 17 '25

Signal cannot allow access to messages. WhatsApp can and does. Opensource vs proprietary.

[Citation needed.]

WhatsApp does not have the keys.

u/Chypsylon Feb 17 '25

At least they claim that but how can it be verified? Also nothing is really stopping them from pushing updates compromising encryption or targeting certain users.

3

u/BWCDD4 Feb 17 '25

The issue for meta is the lack of trust and open source.

They might use the e2e encryption but it doesn’t stop them from implementing client side scanning/key logging.

u/DrEnter Feb 17 '25

So, that "metadata" they collect undermines a key point of Signal's privacy protections: Who is talking to who and when. If you don't think those details by themselves are important, understand that the NSA certainly does because it allows them to undermine free association and organization. Since it's being collected as the innocuous sounding "metadata" and not called something more appropriate, such as "personal communication data", people aren't paying much attention to it being collected, packaged, and sold. But it's important to realize that some of the buyers are companies like Wal-Mart and Amazon, and they are using that data to undermine attempts of workers to form unions.

So, just because WhatsApp is still protecting the content of the communications themselves, don't think for one second that the service is "private" or "secure".

u/josh_the_misanthrope Feb 17 '25

So does Facebook Messenger, but you can recover your data with a six digit PIN. If I can recover my data with a six digit pin, so can a very simple python script in fractions of a second.

I suspect they use the same implementation for WhatsApp, which is incredibly insecure, unless I'm missing something. You shouldn't be able to recover E2E encryption with a password that has a character space of 1,000,000.

Don't trust any encryption implementation you can't build from source yourself, like Signal, because your security is entirely in the hands of a corporation with vested interest in reading your communications. It's like hiring a dingo to babysit your baby.

u/ExplorationGeo Feb 17 '25

You think WhatsApp doesnt have the keys to your messages and wont hand them over to the government when asked?

This was the impetus for us to move over to Signal for my friends' group chat. Say I was critical of a certain country and their policies regarding a migrant workers in that country. Say I got a job offer to work in that country - not unlikely in my line of work. Say that as part of the background check to go to that country, the messenger app I used was told to hand over all of my shit so they could see if I had said anything critical of that country.

After Google's Gulf of retardation capitulation, I'm convinced they'd hand over your emails or anything else. I already assume everything I type on Facebook and it's messenger is compromised.

Until the Swiss and French governments told them to give up radical French climate activists “ or else”.

u/Ozryela Feb 17 '25 edited Feb 17 '25

Those keys are still on my phone though. If I can read my messages, then so can anyone with access to my phone.

I'm not saying it's not better than other messaging apps at privacy. But I don't for a second believe law enforcement couldn't get into the average smartphone if they really wanted to.

Of course if you have selected the make and model of your phone with security and privacy in mind, then that's another story. But most people won't have done that (myself included).

edit Why is everyone responding to me by making the exact same point I just made. Again, I'm not saying signal is bad. I use it myself. I'm just pointing out that you shouldn't make the mistake of thinking your communication is 100% private and safe just because you use signal. Know the limits of the tools you use.

13

u/That_Hobo_in_The_Tub Feb 17 '25

That is also true of a literal note written by hand, if anyone comes into possession of it, they can read it. And if it's coded, they can try to break the code and then read it. So that seems just about as good as it could get in terms of digital security.

Given enough effort, anyone can break into any device if they have physical possession of it, but that doesn't mean the end to end encryption is any less important or useful

2

u/Ozryela Feb 17 '25

Of course.

Again, I'm not saying signal isn't great. I've been using it myself for years. I'm just saying, don't be under the illusion that your communication is 100% safe and private just because you use signal.

2

u/That_Hobo_in_The_Tub Feb 17 '25

That's a very fair point, yeah. I think the issue is just that currently most people assume ALL digital communications are safe and private, so even getting them to start using signal would be a huge jump up from that.

9

u/HowObvious Feb 17 '25

You are just describing xkcd 538.

The moment your communication exits your brain there is going to be some way for it to be intercepted. Its an asinine argument to make.

Also you can set messages to self delete and due to perfect forward secrecy they cannot be recovered with the keys so you are simply wrong.

3

u/6198573 Feb 17 '25

How else would you expect it to work?

Your phone getting in the hands of LO is the end of the line

Either delete your messages as they come or don't use a phone for messaging

The point is that your message can't be read by simply accessing a server or intercepting them, which you would be unaware off

2

u/UGH-ThatsAJackdaw Feb 17 '25

If you want flawless security, the only solution is to keep the information locked in your mind. If you're typing a message to another person, there really is no safer way to do it. If a person is handling information that is sensitive, its up to them to do so responsibly.

u/UrbanPandaChef Feb 17 '25

My problem with Signal is that they do what every other niche strongly principled FOSS project does and take things to extremes, sacrificing UX to an insane degree. The Signal mobile app used to fallback to texting if there wasn't a connection or the other person didn't have Signal. I managed to convince several people to move over because it could also function as a replacement for an SMS app.

Then in their brilliance, Signal removed texting because it is insecure. That might be true, but it turns out most people don't have friends on Signal or end up in places where data won't work or is expensive, but SMS is still fine. Every single one of my friends uninstalled it.

13

u/UGH-ThatsAJackdaw Feb 17 '25

"I'm mad because they wont compromise their mission statement for my wants. It doesnt matter if this tool protects dissidents from government persecution, security only matters in theory. NOTHING should compromise my convenience."

If you dont have any need for privacy, then Signal may not be the app for you.

-1

u/UrbanPandaChef Feb 17 '25

They had so many options aside from outright removing it. They could've encrypted the text over SMS if the contact is marked as having Signal and a user could've just toggled an option to never fallback or use SMS.

I want privacy, but I can't have it if my contacts don't adopt it in the first place. Adoption of the technology is also an aspect of things like this that rely on your social network. A chat app that no one uses is useless and I say that while still having Signal installed for the few people in my circle who use it.

u/kaychyakay Feb 17 '25

The most important reason you should want it is because one of the 2 co-founders/creators of WhatsApp, Brian Acton, is now the CEO of Signal.

He created WhatsApp back in 2009. After FB bought it, apparently it was promised to them by Mark Z that he will keep WhatsApp as it is and not turn it into an ad behemoth, but as is his nature, he reneged on his word and now WhatsApp is overrun with random brands pinging us about their offers.

Jan Koum left FB, and later Brian left it too in 2017, angry with the way WhatsApp turned out under FB. Brian then went ahead and co-founded Signal Technology Foundation in 2018, which gave result to the Signal messaging app.

The same Brian who created WhatsApp tweeted out in support of the #DeleteWhatsApp trend on Twitter some time in 2020-21.

All in all, Signal is a trustworthy messaging app, and has just about every feature WhatsApp has, with added encryption. I am trying hard to recruit my friends and family over to Signal, but breaking ingrained habits & convenience is just too difficult!
