Greetings!

A friend of mine wants to be more secure and private in light of recent events in the USA.

They originally told me they were going to use telegram, in which I explained how Telegram is considered compromised, and Signal is far more secure to use.

But they want more detailed explanations then what I provided verbally. Please help me explain things better to them! ✨

I am going to forward this thread to them, so they can see all your responses! And if you can, please cite!

Thank you! ✨

    In my view, by far the biggest reason to switch is that Telegram doesn’t end-to-end encrypt chats by default.

    Yes you can start encrypted chats specifically, but i’ll bet 99% of chats on telegram aren’t encrypted - meaning whoever has access to the telegram servers can read all the messages.

    Signal claims to end-to-end encrypt all chats by default, and if you want to be 100% sure you can in theory read the source code and compile the app yourself. this means signal cannot read any of your messages, even if police asks them to or servers get seized. That’s a massive advantage in privacy.

      Additionally, E2E chats don’t sync between devices (and iirc you can’t use them on desktop at all), and group chats can’t be encrypted at all.

      Then talk about coding. Non-techies curl up into a ball and die slightly inside as they run for the exits.

      Highest form of encryption possible.

      Try it

      And if that is not enough to kill someones spirit and make them beg for mercy, recite random sections of the GNU Make documentation out of context and watch them go into convolutions.

      Get what you are trying to say but both are still encrypted. They simply aren’t end to end encrypted. So the messages are private. Until obviously the company servers get hacked or police raided and the keys to the encryption get stolen. You are protected against this in E2E encryption. True.

      Ii guess telegram once was the alternative to whatsapp, then made maany more featutes abailable in fast time paces which led to another bunch of migrators.

      Now noone wants to move away because why? For the usual end user there is no negative to them.

      I am fully on your side and am using signal and matrix and try to migrate as many people as possible but its hard.

    I can’t speak about telegram, but signal is absolutely not secure to use. Its a US-based service (that must adhere to NSLs), and requires phone numbers (meaning your real identity in the US).

    Matrix, XMPP, or SimpleX are all decentralized, and don’t require US hosting.

        As an outsider, I mean isn’t that the same for news coverage for chinese/russian backdoors, but everyone believes it without any proof.

        Why is US company being a US honeypot a big surprise, and its government recommending it not a big red flag? but it is when China recommends wechat? Can’t we be critical and suspicious of both authoritarian countries?

        Do you have access to Signal servers to verify your claims by any chance? Afaik their servers are running modified codebase, and third party apps cannot use them. So how do you claim anything that goes behind closed doors at all? Genuinel curious.

          Do you have access to Signal servers to verify your claims by any chance?

          That’s not how it works. The signal protocol is designed in a way that the server can’t have access to your message contents if the client encrypts them properly. You’re supposed to assume the server might be compromised at any time. The parts you actually need to verify for safe communication are:

          • the code running on your device
          • the public key of your intended recipient

      So if I understand it Signal has your phone number but only logs sign up date and last activity date. So yes they can say this person has Signal and last used it on date X. Other than that no information.

      Matrix doesn’t require a phone number but has no standard on logging activity so it’s up to the server admin what they log, and they could retain ip address, what users are talking in what, rooms, etc. and E2EE is not required.

      I think both have different approaches. I’m just trying to understand. On one hand you have centralized system that has a standard to minimize logs or decentralized system that must be configured to use E2EE and to remove logs.

        They have your phone number (meaning your full identity, and even current address), and as the primary identifier, it means they have message timestamps and social graphs.

        Its impossible to verify what code their server is running. Or that they delete their logs, because they say they do? You should never rely on someone saying “just trust us”. Truly secure systems have much harder verifiability tests to pass.

          I am not uneducated in this matter, I run Matrix instances and have dabbled in development of tools around it.

          Perhaps our experience is different, but I have had great difficulty in helping groups on the ground to use Matrix.

          Regardless of our agreement that Matrix is better than Signal, it should not cloud our judgement in at least reducing the harm that is Telegram.

          In the future we can keep joining hands to work towards a better future, but for now I hope you can understand my perspective and choice.

          Matrix is centralized around Matrix.org or servers they run tho. Since the protocol is a big data/metadata sync by design & medium–large-sized servers are expensive to run, almost all of metadata is with Matrix.org—of which was originally funded my Israeli intelligence & I wouldn’t be surprised if they were getting data out of it to this day.

      As you say yourself (cryptocraphic nerd here):

      Signal’s E2EE protocol means that, most likely, message content between persons is secure.

      So a shame there are no free servers, are the server soft not open source, only the signal app itself?

        The server is supposedly open source, but they did anger the open source community a few years back, by going a whole year without posting any code updates. Either way that’s not reliable, because signal isn’t self-hostable, so you have no idea what code the server is running. Never rely on someone saying “just trust us.”

          I have read that it is self hostable (but I haven’t digged into it) but as it’s not a federating service so not better than other alternative out there.

          Also read that the keys are stored locally but also somehow stored in the cloud (??), which makes it all completely worthless if it is true.

    It really depends on who your friend is, and who they are trying to defenf against.

    If the US ( or Russian / Chinese) government really wants to access an internet-connected device, they can do it; what app you are using doesn’t even matter. For example, most people use the default Google keyboard, which could be compromised.

    If the concern is about local goons / employers / coworkers, then both Telegram and Signal are more than enough to stop them prying.

    As for whether to use Signal or Telegram, Signal has end to end encryption enabled by default, while in Telegram you have to switch it on for each chat. On the other hand, Telegram has the best UI among messaging apps hands down.

Can read your screen, microphone, and etc. I’m not really sure what you should use unless you use coded language. Even then, there’s just too much information about you out there anyway. Best bet would to be have conversations in private away from any electronic devices or use something like tails.

    Telegram for random public chatter/file storage(with password lock), talking to strangers without giving them your number. Signal for personal/private conversations.

    Spread your data (encrypted or not) around, so a single entity doesn’t own your digital life. Your device can handle 2 apps and don’t give them permissions willy nilly. Geez, every one of these posts just wants to start a flame war.

      In Telegram, you never have to expose your phone number. If you like walking into traps then of course you can.

      But can make minimal efforts to not be a degenerate avoiding this obvious easily avoidable trap.

      How to avoid exposing your phone number

      Make a group called i'm not a complete utter idiot. Whenever you have a friend wanting to connect, make a group link, send it to them, have them join. After joining have them send a message in the group. Just, “Hi”. Nothing more. Less is more.

      Look for that message and click on the person’s name. You are now connected. Send them a personal message, “Hi!”.

      You can also add them as a contact without sharing your phone number.

      Your friend will probably be a degenerate and expose their phone number. Teach them how to go into settings to always hide it.

      Try not to call them a degenerate, degenerates hate that.

      Also try not to think of them as a degenerate, they will already know that and be proud of it and not understand why you don’t share their enthusiasm.

      So control what thoughts you project into the ether. If you have to change the topic in your mind to something involving flowers singing birds and clouds.

    There’s a lot of answers itt but heres a simpler one:

    If you want to prevent people in power from having access to communications there are two methods employed, broadly speaking:

    The first is to make a very secure, zero knowledge, zero trust, zero log system so that when the authorities come calling you can show them your empty hands and smirk.

    Signal doesn’t actually do this, but they’re closer to this model than the second one I’m about to describe. Bear in mind they’re a us company so when the us authorities come to their door or authorities from some nation the us has a treaty with come to their door signal is legally required to comply and provide all the information they have.

    The second is to simply not talk to the authorities. Telegram was closer to this model than signal, using a bunch of different servers in nations with wildly different extradition and information sharing mechanisms in order to make forcing them to comply with some order Byzantine to the point of not being worth it.

    Eventually the powers that be got their shit together and put hands on telegrams owner so now they’re complying with all lawful orders and a comparison of the tech is how you’d pick one.

    The technology behind the two doesn’t matter really but default telegram is less “secure” than default imessage (I was talking with someone about it so it’s on the old noggin’).

    I’m not an expert but I’ll use this analogy.

    Signal is you meeting a person who gives you secure devices. This person then can only ever provide the following information to someone else. From Signal website. “The phone number. the date and time a user registered with Signal and the last date of a user’s connectivity to the Signal service.” Only your device and your friends device can read the messages. It goes direct from you to them. The only way to read any message is having the device.

    Telegram is like you making an agreement with another person. By default messages are encrypted but go to the other person for decryption before going to your friends device. This other person Telegram has and will give the phone number, messages, serverlogs, dates to legal entities by request. Now there is an option to bypass this person by using “secret chats” . This will make it so the message is directly from your device to their device. Telegram can’t read messages but as I understand they can still potentially have metadata, server logs of when messages are sent, how many, what device they are sent from. Bottomline is they have activity logs Signal can only provide the date you signed up and the last time you used the app. Not only that but just being on the Telegram platform which allows bots makes you a target. Bots will contact you like spam. Sending you harmful links, etc.

    Almost every security person I’ve ever read says. “I use Signal”. Why wouldn’t you go with the service that by default has end to end encryption? Telegram makes it a option you have to select for each person. Both use your phone number.

    These are very basic descriptions. I’m Happy to remove or update if I got anything wrong.

        What does Telegram do better and how?

        User experience, like I said. How many less technically inclined people do you know who will understand why they have no message history in Signal after moving devices? Yes, they could have kept it if they’d had backups enabled and moved the archive over and restored from it, but it’s too late now, their entire contact list has been notified that their safety number’s changed (another aspect we get to attempt to explain). It’s a bummer.

          Message history is a valid point. Signal just announced they’re fixing it.

          Safety number change notifications are probably necessary to maintain Signal’s high level of security. The above device linking improvements should make them less frequent, though I’ll concede some might consider that a worse UX than an insecure chat with no such notifications.

      Apparently Signal still requires it, though you no longer must reveal it to others.

      Wired last year: Signal Finally Rolls Out Usernames, So You Can Keep Your Phone Number Private

      Those features, which WIRED has tested, are designed to allow users to conceal their phone numbers as they communicate on the app and instead share a username as a less-sensitive method of connecting with one another.

      Whittaker says that, for better or worse, a phone number remains a necessary requisite as the identifier Signal privately collects from its users.

        Apparently I still don’t have one. Haven’t had a phone number for about a decade. No SMS spam, no “survey” calls; nothing.

      This is unfortunately completely wrong, since you can learn from the homepage of matrix very own client Element, that its supported an trusted by a whole bunch of NATO Armys, including the US of course…

      I don’t mean by that you shouldnt use matrix, but arguing against signal with matrix is, in so many means, hilarious.

      The arguable, but professional cryptographer soatok discribes from a mathematical/cryptographical point of view, what it needs to be a Signal competitor, where matrix (and others) dont catch up (unfortunately)

        Used by a bunch of NATO armies isn’t the same as promoted by or made by. It just means they trust Element not to share their secrets. And that blog post is without merit. The author discredits Matrix because it has support for unencrypted messaging. That’s not a negative, it’s just a nice feature for when it’s appropriate. Whereas Signal’s major drawback of requiring your government ID and that you only use their servers is actually grounds to discredit a platform. Your post is the crossed arms furry avatar equivalent of “I drew you as the soyjack”. The article has no substance on the cryptographic integrity of Matrix, because there’s nothing to criticise there.

        Sure. You can trust your own fork. Just don’t use the official repos or their servers. The client isn’t where the danger is.

            Your client talks to their server, their server talks to your friend’s client. They don’t accept third party apps. The server code is open source, not a secret. But that doesn’t mean it isn’t 99% the open source code, with a few privacy breaking changes. Or that the server software runs exactly as implied, but that that is moot since other software also runs on the same servers and intercepts the data.
