for Mattermost, what is meant by 'gateway to other services' ? API integrations?

Yes; but I'm not a Mattermost expert

Olvid

Olvid sound promessing, we cloud also talk about Threema which is more or less the same but developed in Switzerland. but at the end I took my list from AlternativeTo.net and took the top 10.

Beware most of VOIP use opportunistic encryption mainly because of issues with NAT so trusting a 3rd party for that is a big mistake for your privacy.

These days everything is secure like email aka the authentication use SSL than the message follow in clear text.

It would be interesting to find how/if Olvid encrypt their VOIP and which part ANSSI complement.
for now I only see the text message being encrypted.

mehdi

@jodumont I am of course only talking about good end-to-end encryption, like Signal or WhatsApp (yeah, WhatsApp has many flaws, mainly their owner, but they do have good encryption).

I don't know about Telegram's encryption, I never looked into it. I just know they don't use any by default (which, in itself, is bad)

mehdi

@jodumont about Olvid, from what I know, yes their calls are also encrypted, but they are only available for paid users.

we probably don't talk about the same phase of encryption, you seams focusing on the message (which obviously it is important) and I'm talking about the transfer

anyway good thing this forum is encrypted by a SSL

mehdi

@jodumont This table seems to be either outdated severly, or just plain wrong. Whatsapp does use end-to-end encryption, and has been using it for years.

I came across a couple of nice chat comparisons recently.

First of all there is this nice infographic by niboe.info

Sadly I've been unable to find an English version of the other nice infographic in this accompanying article of theirs in Spanish.

I also came across this handy table from DivestOS (a privacy focused Android distribution):

https://divestos.org/index.php?page=messengers

Both of these make we wish Cloudron had an XMPP server like ejabberd so we could get our friends to try out Conversations and Movim (I mean, both Yunohost and HomeLabsOS have an XMPP server, and they are both fully open source and run by volunteers - whereas Cloudron is the one with a business model and full time paid @staff - and yet they've got XMPP and we don't! )

JOduMonT

maybe me, but personally I make a difference when you are able to generate or add your own key to encrypt versus the "platform" provide you the public and private key

mehdi

@jodumont The key is always generated on your own device. There is zero reason to allow users to import an external key. If you don't trust the local app to correctly generate a keypair, you have no reason to trust it to correctly perform the encryption. So importing a key brings nothing.

robi

@jdaviescoates time to host an event, start packaging and get help finishing it!

jdaviescoates

@robi I've often thought of learning to code. I loved maths as a kid. But now isn't the time.

robi

@jdaviescoates there's no real coding involved.. it's mostly stitching things together and adjusting configs. You'll have help too.

marcusquinn

Looks like Signal App's addition of payments using MobileCoin ($MOB) has struck a raw nerve with many.

Another alternative that seems to come up regularly on the comments underneath their Tweets is this Session App:

https://getsession.org

YMMV but another one for the list and your esteemed critique.

jdaviescoates

@marcusquinn see also Snikket which seems like a great option too (and gets my vote for the XMPP that ought to be first added to Cloudron).

atridad

I'd still take Matrix over all of those for its decentralized and federated nature. It is incredibly secure and their Element client has truly come a long way. I would love to see Snikket and Oragono though. I tried packaging Oragono but lost the motivation part way through as I usually do.

But my vote for matrix comes in here: Me and a friend could both have our own homeservers and still chat in a secure manner. If we're talking privacy, I'd say its at the top for sure.

jdaviescoates

@atrilahiji true, although I find Matrix to still be somewhat of a UX nightmare. It's often very confusing, even for geeky people.

atridad

@jdaviescoates I mean, I wouldn't say I'm an expert in UX so I can't speak to that but I can say that for me I found it fairly intuitive. I know that this may not be everyone's experience though.

I also am wary of UX issues or incredibly pretty apps sometimes because I find that a lot of apps seem to go 110% in on beautiful and intuitive UI while compromising on core functionality.

marcusquinn

I think any app requiring a central server will remain niche.

Signal took a long time to persuade people to switch with very low signup friction.

User experience is as fundamental to security as shoes are on gravel.

If the experience doesn’t factor-in user onboarding time & friction, then it becomes a security issue in itself, by discouraging critical-mass adoption to be more useful than the ad-tech alternatives.

Did you mean apps not requiring a central server? Looking at the current abysmal state of the internet, apps requiring central servers dominate.

Signal took a long time to persuade people to switch with very low signup friction.

If the experience doesn’t factor in user onboard IG time and friction, the it becomes a security issue in discouraging critical mass adoption to be more useful than the ad-tech alternatives.

I think this is a good ol' agree to disagree situation. I'm of the opinion that if someone needs to be coerced into caring about security they may as well stick with selling their soul to Sundar Pichai and Zucc. As far as I'm concerned the best privacy chat app is the one that best protects privacy. Simple as that.

marcusquinn

@atrilahiji The family reeeeeeallly resisted the push to Signal for months, these are people that care, and I care about, but the "why should I?" brainwashing runs deeper than personal and relationships nowadays.

That's the power of user experience and trust in exchanging effort for that.

For business and professionals, sure, we have some influence, but for personal, I'm afraid the user statistics speak for themselves.

marcusquinn

@atrilahiji Moral hypothetical; mental health is an issue, I think we can agree on that?

How do we reconcile having capabilities to improve user experience and adoption, against having people we care about unnecessarily unhealthy in mind because they "sold their soul", or more likely it was bought and sold for them?

atridad

@marcusquinn I mean yeah, for a number of people the security aspect is something of a non-issue. What moves them is the UX. But I'd argue that most, if not all, open-source chat apps that allow for self hosting simply cannot compete with Signal because people move to the shiny thing. You and I know that there are better options if privacy is the concern, but for the majority of people privacy truly is not a concern. If it was, we wouldn't even be having this discussion and everyone would use Matrix.

But where I'm coming from here is solving the core issue of the best privacy chat app, which I still argue is Matrix. I would not say it is the best chat app. But again its a matter of what one prioritizes.

Robin

@atrilahiji Well, you also don't really need to compete with Signal if you can use it as a trojan horse using e.g. https://docs.mau.fi/bridges/python/signal/index.html. Of course, this comes with its own set of challenges: making a good experience with many moving parts is not easy - and bridges are inevitably another moving part, often of questionable quality since they aren't a primary focus.

marcusquinn

@atrilahiji Yeah, it's a compromise step I feel. Secure enough to be better than ad-tech's conflicts of interest, but still aware that the metadata for who's chatting with whom and when still has some potential value that one wouldn't want to share if given an assured choice.

Matrix I love the ideals and successes of. Element seems the best of the bunch. So for this audience, certainly the best we have.

For my entire social circle, well I can't see it happening but would be happy to see otherwise.

I guess the original point of the post was non-Cloudron specific, and potential for mass-market.

I guess we have to wait and see what Elon Musk shills next if Signal's MOB payments sour the new kid capturing mindshare.

The Very Best Encrypted Messaging Apps:-

Signal
Wickr Me
Dust
WhatsApp
Telegram
Apple iMessage
Facebook Messenger

App to avoid: Google Hangouts. Despite being available for free on both iOS and Android, Google Hangouts is riddled with privacy and security concerns. Though it does encrypt hangout conversations, it doesn’t use end-to-end encryption — instead, messages are encrypted “in transit”.

atridad

@atupuxi Good to see Signal on there but WhatsApp and FB Messenger are suspect. I'd probably put something like Matrix (Element) on there. Probably even above Signal since you can't quite self host Signal.

@necrevistonnezr IMO I'd remove anything that is owned by big tech OR is closed source from that list. How can we ever ensure a closed source application is secure?

Or in other words, just refer to the great infographic I posted earlier.

atridad

@jdaviescoates This is perfect.

IMO with the Spaces beta Matrix (using Element as the client) is very good in terms of usability. I use it with family and friends now and its been effortless.

Now we just need Dendrite packaged for a server... unfortunately I know next to nothing about packaging federated apps so I'm hoping someone else will try before I hack something awful together.

robi

@atridad The example package is there with Matrix server no?

atridad

@robi Oh I mean we do have the Matrix Synapse server written in python. The team behind Matrix is working on another server called Dendrite written in go.

robi

@atridad right, other than the language difference, the 'federation' packaging should be the same, yes?

Personally, I don't like Signal, for it is just another WhatsApp were you could be tracked by GPS/Beacon and meta-data. I saw too much anti-government group using Signal and being intercepted simply by correlating the high level of exchange in Signal (metadata) and movement tracking (GPS).

For the fact, saying Close Source is not secure by default, it is simply a point of view. Few companies with whom I work do business with the military and don't want to use anything Open Source because for them Open Source sound full of flaws and weaken their defence.

@jodumont I read somewhere that the biggest user group of linux is the US military. I'll try to find a source for you. Open source is seen as a positive, not a negative. The military from other nations also use Linux like China and Turkey...

@jodumont SIgnal is by far the most secure digital messaging app usable by normal people at this point and this isn't a controversial point among security folks. No matter app what you use, law enforcement can subpoena your phone's cell tower connection records, among other things(at least in the US).

atridad

Yeah... I'd never be inclined to believe that a chat application is secure unless they are willing to reveal all of the source code. I still use some, like discord for instance simply because I have friends I cannot get off of there. Element with their new Spaces feature has made it usable enough for me to recommend to anyone. Maybe I just don't see the issues because I am used to janky UIs? But I think it is very slick and easy to use at this point. But regardless, I don't want to confuse the conversation about what is easy to use with what someone is used to.

marcusquinn

There's another element to choice of communications apps, and that's the democratic vote that it represents as to whether you endorse a company and its ethics or not.

Facebook raises it's value from the number of users and interactions, reduce that and you reduce their value to advertisers and shareholding investors.

Full privacy is almost impossible - but portability and freedom of choice should be encouraged, and even one movement away from a tech giant is a small win against their mindshare domination aspirations the seem to presume in trying to become an essential utility for most.

@marcusquinn

Thanks; this caused me to think of Mike Masnik's paper emphasizing endorsement of protocols instead of platforms, might perhaps be relevant / interesting.

@martin Yup, also reminds me of the quote to paraphrase; "Bad things happen when good people do nothing."

I'm sure your right, and I'm fully for OpenSource and choose OpenSource by Default, simply, sometimes, some irrational thought are hard to destroy

Just randomly found this via GitHub: https://berty.tech
a privacy-first distributed messaging app.

jdaviescoates

@jodumont sounds very promising

"Berty is still under active development and should not be used to exchange important data.

The current Berty Messenger implementation is not using the Berty Protocol yet, but OrbitDB directly. Which means the encryption is not safe, but the good news is that the current Berty Messenger app is already a P2P one!"

Just stumbled across this, maybe interesting, well reviewed too:

doodlemania2

yall should also check out Session (getsession.org) it's pretty sweet - a fork of Signal protocol with the backend using the Loki/Oxen network and in the table above, requires zero of the 19 permissions that Signal requires. I personally REALLY enjoy it.

The downsides are obvious here in the usability department. In order to get to chatting with someone, you HAVE to exchange keys. Signal makes that easier cause they generate QR codes but also integrate with your contacts.

One thing to note, however, as a plus to Signal, is they use confidential computing on Azure to hide all the contacts processing, which is a really great use of that particular tech.

marcusquinn

@doodlemania2 I did give Session a try, kinda felt primitive and like persuading anyone to switch from Signal would be at the expense of losing features for marginal additional privacy.

get that the metadata with Signal isn't private, and that's annoying, but the main thing for me is avoiding using Facebook/Google products.

I'm sure Session will continue to evolve, so hopefully they don't lose momentum and have the capability to reach feature parity with the current most popular apps.

ianhyzy

@marcusquinn yeah, a lot of alternatives to signal look neat but fail at being cross platform or easy for normal people to use

atridad

I've had to ditch Signal. It has been a nightmare to use. Notifications on Android and iOS are both spotty. My mom had missed calls several times because it just never rung for her (I verified this). Also for video calls it occasionally decides speakerphone is not needed, and won't work.

0/10 somehow Element + Matrix is more usable.

robi

The frequent disconnections from Telegram and Signal are problematic.

It's like someone is deliberately disconnecting all sessions they can't intercept. Making it a lot less reliable.

Sometimes video calls are better, and you can always stop video sharing, keeping the voice channel open.

Same with GVoice calls, frequent drops, despite good networking on both sides.

One of the better things for longer lasting voice comms is Team Speak. But the lack of availability of free clients on mobile puts that in the 'only at home' category.

Cloudron makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server. Find out more or install now.
