The creator of Pixelfed announced an upcoming encrypted messenger for the fediverse that will work across the fediverse

It will be open source, end to end encrypted using Signal’s double ratchet encryption protocol, and he plans to make it easy for fediverse platforms to integrate it. The beta will release later this month.

He’s also the creator of https://fedidb.org btw

While I doubt I could get my friends and family on yet ANOTHER messaging app in the year of our lord 2023.

Sup. Is a fucking brilliant name.

Could be a fantastic way to replace dm, that's my first thought.

I remember idly wondering how DMs worked in Lemmy, and I was kinda shocked when I realized they aren't secure.

13

"secure" is relative. They may not be e2e encrypted, but they are still encrypted via TLS, like any HTTPS traffic. It's the same encryption used for online banking. If you care about your instance admin being able to read your messages, you should use Signal or a Matrix client though.

But remember that only a few years ago, almost nobody used e2e encryption, and it wasn't much of an issue.

I personally hate the name, but only because I had a roommate in college who would start every conversation with “sup.”

On text messages, IMs, in person, you name it. It really started to get under my skin.

But I hope the software is good.

Yep. That’s what he’d do. So basically he’d always want you to start the conversation.

I've not been on either platform long enough to use the DMs, but this is a good point.

After all, DMs aren't actually private on either platform, as far as I'm aware.

sabreply
kbin.social

If they're not end to end encrypted, your messages are not actually private on any platform.

It's a bit more obvious in the Fediverse than elsewhere, as direct messages are generally stored on two separate servers (sender and receiver). Furthermore each server tends to be smaller: if Zuckerberg decides to go through people's DMs it's unlikely to affect any particular Facebook user, but if the owner of a Mastodon instance does the same it's small enough that she could actually get an overview. It's mostly a false sense of security embedded in larger services, but people are all about having a false sense of security.

22
lemmy.sdf.org

Like anything, depends on the threat model. Private from your little sister? Probably. Private from your boss, at least in the next few months prior to them being leaked? Also probably. Private enough?

That's to some extent a question that can only be answered individually, as everyone's threat models differ. I suppose this fact (everyone having differing threat models) is one of the reasons that so many arguments occur over security.

9

In the end any successful chat service is going to be used by horny teenagers sharing nudes with each other, which is honestly for me better reason than any state secret why all communications should be end to end encrypted at all times. I don't trust Zuckerberg or Musk with that, or any other third party for that matter.

5

Yep. That was my first thought - how everyone says to use Matrix rather than Lemmy DMs for anything sensitive. This will be fantastic.

14

Right now I just think about me and how I'll use it. I'm eager to try this messaging app to have a way of being reachable by like-minded people.

To put it differently, I don't want to be a slave of others' choices. I know the network effect is real and that I'm powerless to break it. So I'll just change my attitude, and embrace this wave. Who knows what will happen? And in the meanwhile, I'll have fun using what to me seems right.

1

It really is. In the past a new messenger or Plattform was always annoying as it inevitable meant, how can I get my friends to use this. But with activity pub it doesn’t matter anymore. Everbody can use the fediverse software of his taste and we can still all be interconnected. What a relieve. So many software solutions can compete against each other without us having always to start from zero. Brave new world.

I wonder if he is friends with the guy who runs calibre and kitty terminal. I read somewhere that he was seriously planning to single-handedly maintain python 2 after it was EOLed because it was so integral to calibre. But was eventually talked into transitioning to python 3. The idea of that is totally nuts; the guy is a machine.

I've been unhappy with the direction Signal has taken in recent months and Matrix always felt like it was trying to do too many things at once.

Happy to see something that would integrate directly into Fediverse platforms as it will greatly enhance interplatform communication.

lemmy.ca

I agree. As soon as the update that disabled SMS was pushed to my phone, signal was effectively dead.

Integrating with SMS was so smart. The person who got me into it said "there is literally no reason not to do it" because it was seamless. And I used the same argument to get other people into it. But basically everyone stopped using it as soon as SMS was removed. I don't have the brain space to remember who is on signal and who is not and go to the appropriate messenger.

I read the whole long thread on their website where the devs were arguing in favor of this and all the reasons were IMHO stupid. I think someone wanted to tank signal. Got tired of funding it probably. It was too good to be true with no obvious business model so always thought the day would come, and it did. Too bad, it was very good at what it did.

5

I think someone wanted to tank signal. Got tired of funding it probably.

This take doesn't make any sense. Signal is funded by a non-profit and has tons of money that allows them to not worry about funding in the near feature. There is nobody to "get tired of funding" them.

Makes a lot more sense when you realize they hired an ex-Google exec to run Signal.

I've posted this previously, but I'll repost again because I think its important people are aware when making a decision on a secure messenger.

======== Original Post: https://lemmy.ml/comment/1615043

Sessions developers dropped Signal's Perfect Forward Secrecy (PFS) and deniability [0] security features. Personally I would not trust a product that drops an end-user security feature for the sake of making the developer's life easier [1] .

Using existing long-term keypairs in place of the Signal protocol massively simplifies 1-1 messaging.

For those unaware, PFS protects your data/messages from future exploits and breaches. With PFS, each message's encryption is isolated, preventing compromise of current and past interactions [2].

A simple example to illustrate why PFS is beneficial. Lets assume any 3 letter agency is collecting all Signal/Session messages - on top of the tons of data they're already capturing. The great thing is that your messages are encrypted, they can't see anything - YAY - but they're storing them basically forever.

Two ways they may be able to compromise your privacy and view ALL your messages:

  1. A flaw is discovered that allows them to crack/brute force the encryption in weeks instead of years/decades/eternity. If you were using Sessions, because you use the same key for every message, they now have access to everything you've ever said. If you were using Signal, they have access to that one message and need to spend considerable resources trying to crack every other message.

  2. Your phone is compromised and they take your encryption keys. If you were using Sessions, this again gives them access to your entire message history. If you were using Signal, because the keys are always rotating (known as ephemeral) they can only use them to unlock the most recent received messages.

It's important to state that both cases above only really matter if you delete your messages after a certain time. Otherwise, yes, all they have to do is take your phone and get access to your entire message history - which is why ephemeral messaging (i.e. auto deleting messages after a certain time) is crucial if you suspect you may be targeted.

Oh god matrix is such a bitch to handle and deal with, laggy and just in need of so much work. I'll be so happy to have an alternative.

I used it and hosted it for months with friends and family and we all got locked out due to bugs and had neighboring federated servers that wouldn't connect.

lemmy.world

What year? I've run a docker synapse for a couple years with no issues (other than iOS client encryption bugs). I was surprised I could run it without a restart for 6months+

6

This year. I gave it a VPS with plenty of cores and memory too. It's like once I got it working it would work for awhile right, nbd. But then when I'd join a federated room over on matrix.org it would literally take days to add it. I even smoke tested it with their federation tester.

The lockout I'm describing is like an auth bug. The moment you sign in in a couple different places it has trouble unencrypting messages and even if you verify the other devices identity it will act like it's still unrecognized, and delete messages. It happened to my girlfriend, then my friend, then me. Twice in two separate attempts to use it daily. I tried using it as a complete iMessage replacement across all platforms so I'm saying I was using it heavily.

And yeah I used docker too. It's a neat concept it just falls apart at scale from what I've literally seen twice. Doesn't matter what client I used either.

just yesterday element literally gave up on joining the nix matrix space after staying at joining for hours on my selfhosted dendrite instance

a week or so ago the exact same thing happened with the arch matrix channel

I'm still trying to figure out why this would be used over Matrix. It seems to be the same without bridges?

4

this rocks actually. I've kinda wanted this for a while

35

I’m not leaving Signal until someone implements keeping data at rest encrypted on both ends and requires multi factor unlock (bio+pin is my choice).

So sick of E2E clients that leave the data in plaintext on the devices and then back it up in plaintext to the cloud.

34
lemmy.sdf.org

Does Signal back up in plaintext in the cloud? (If so that doesn't sound like E2E encryption… unless the 'ends' are uh… also constituted as the cloud itself which is… defeating the purpose).

Where do the pub/ private keys live, exactly, tbh. (Assuming it is asymmetric encryption that they use?)

Edit: ah, misread. I thought you said that you were not joining it due to it storing plain text in the cloud.

1
lemmy.world

Hm... If they're not being stored on the cloud, that means offline users would never receive messages, unless Signal is purely P2P. I haven't looked at the project, or the source, but I find it hard to believe -- you can't really do user lookups without some sort of middleware in the cloud.

2
lemmy.ml

You're right, Signal is not P2P. The way Signals messaging pipeline works is like this - note I'm oversimplifying it for accessibility.


Sending a message to Bob

  1. You press Send.
  2. The message is encrypted on your device with a key that can only be unlocked by Bob.
  3. The message is then "sealed" so that there's only a "deliver to" field visible (not a "from").
  4. The "deliver to" field is addressed with a hashed/salted label for Bob - this means Signal's server can see its a unique user, but not what their name is.
  5. The message is finally sent to Signal's servers.
  6. Your message sits on Signals servers until it can be delivered to the intended recipient.

you can’t really do user lookups without some sort of middleware in the cloud.

See their blog post about Private Contact Discovery, they've spent a long time figuring out how to engineer a method to know as little as possible about you.

2

Yeah, but messengers, such as WhatsApp for instance, will send you missed messages once you're back online. That's what I was referring to.

Chill, you’re not the only one here.

VoIP in a mainstream messenger is something that most people use nowadays to avoid calling people from their SIM cards which costs them much.

Video calling too is something I personally use too especially on iMessage or Telegram.

I’m a software engineer, I appreciate some old school things that work perfectly well like ICQ or Vim or emacs or working only with shortcuts. But you know what’s also a shortcut? Not having to use 50 different messengers just because this one doesn’t have VoIP and I can’t bring my friends or my mom here but I can bring only my nerd friends”.

This is all business and target audience oriented. You are not the only target audience out there and especially when you don’t demand from a messenger to be able to have VoIP. Even Instagram has VoIP these days. A photo-video-media sharing app. Let alone a messenger.

yeah, the app is made for you and him. So doing the math we have a -1 "VoIP is not something I'd care about" and a +1 "Video calling too is something I personally use..." which results in 0% significance. So let's just talk, voice our opinions, and chill.

No, the app is made for everybody who wants to use a messenger. Not just you and him. It's supposed to be under the standards of the feddiverse.

The comments here are not a poll. Providing especially personal comments about a nerdy user like me and the guy I replied about "I would like it like ICQ" and such shit, would not help the creator make a good choice. Most people nowadays, especially zoomers, dont even know what ICQ is or how it works or how to even login to it. Most people, proven by ehm ... the success of messenger, discord, whatsapp, telegram, viber, signal everything ... want a messenger that provides what the mainstream messenger wants with most of the features that everybody provides and are mainstream used while having ease of access.

We should try to help the creator. Not misguide him. Again, the comments are not a poll, they're supposed to help to make a constructive conversation. And when you talk as if the app is made only about yourself, you're not really helping.

I wonder, what 'works with the fediverse ' could mean for a messenger and what could be features not already implemented by different messengers, like elements or the very signal.

25

From the side of the Messanger, it could implement stories from pixelfed and communities from Lemmy/mastodon/kbin etc.

I don't know if anyone is asking for this, but Whatsapp has both, so someone must be using them, right?

As from the side of every other fediverse app, I think it could be a good way of implementing DM functionality without developing and maintaining it for every single app. Maybe. I don't know really, depends on how it's developed/implemented

I'm not a fan of Pixelfed, or instaclones. But the idea of a messenger e2ee that works with all the fedi is such a awesome idea.

One of the most used feature of Facebook and Instagram is their messenger. It's much easier for people to use the same account they use for social media to communicate with each other. A direct messaging feature within fediverse would augment the current ecosystem and make more people transition away from big corporations

3

I see, makes sense. So if I get it correctly, the idea is to make it easier for new people to join the fediverse, and not so much to improve the experience for those of us already here (although it seems that is also a goal).

wewbullreply
feddit.uk

I have no idea what the fediverse brings to an E2EE IM app. They seem like contradictory concepts.

10

All existing messengers have "no walls" if you consider they all transfer data via TCP/IP. Except the wall is the encryption/higher level protocol. Now just replace TCP/IP with federated servers. Different messengers will be unable to communicate with each other because they'd need to implement the same encryption.

If you're able to standardize the encryption then things can interoperate if it's fediverse based or not.

2
programming.dev

According to this post, Signal can federate, but chooses not to. In another post, it's said that Matrix is based off Signal.

So, one way to look at it announcement is "you will be able send Signal/Matrix messages from your fediverse instance of choice", I believe

4

To be a bit more precise, Signal is against federation from two angles:

  • Innovation: Signal values absolute control over the protocol so that they can more rapidly implement UX experiences scene in other modern messaging apps. It also eliminates malicious or outdated servers changing the UX between users. Ultimately folks won't blame the servers, they'll blame the app, and stop using it.

  • No rope for users: They seem pretty confident that the Apple-style of software and UX is right— if a user can change stuff enough to break it, they will. For secure messaging, they'd rather users have fewer choices to be sure it is secure.

“you will be able send Signal/Matrix messages from your fediverse instance of choice”

While no details are clear, it'll definitely not be this. Matrix has it's own implementation which isn't compatible with signal (megolm or something like that), and I really don't think dansup will be making it matrix compatible. It'll probably be its own thing.

I'm not sure it means the apps will be interoperable, only that the protocol for sharing keys will be standardized.

Competition is good, especially with regards to privacy and cyber security. Customers benefit when companies don't have a captured market. A lack of competition only leads to monopolies and stagnation.

If no one offers a secure product, then customers have no choice but to either not use anything or put up with it. Competition means that at any time a newcomer can offer a better product (that is hopefully open source).

Edit to add: Ideally you could message people on different apps with the same account. But I'll take fragmentation over a monopoly.

Matrix has this. It's federated but doesn't communicate with Lemmy.

4

I’m not disagreeing with you. You’re saying that the fediverse produces badly designed and branded services that mirror existing apps with massive user bases, that won’t be great until a lot of users migrate over. None of that is wrong! It’s why Lemmy is a mess that constantly breaks, and Reddit is still way more useful, even if most people here hate it.

It’s just that most Lemmy users care enough about decentralisation to ignore those product downsides, in the hope that they it can be overcome over time. With a messaging product, that’s even easier. You can just install it and wait until other users join - network effects are ’much more limited than with eg Lemmy.
