Hey all, what communications protocol does signal messenger use. Do they use websockets, or http streaming or what do they use?
I understand that a pro of OSS is that it allows users to know if they are being tracked. However, how can I be sure that the code on GitHub is actually being deployed to the iOS App Store, and there isn't some private Signal fork where they add data tracking that actually gets sent?
Thanks!
Asking this because I don't know of any truly secure to collaborate live on documents (obviously with the server being self-hosted)
The deal is, when reinstalling WhatsApp it came to my attention that I received my old messages (on an entirely new device without even GSF!). When reinstalling Signal and resyncing the desktop client of course it does not download old messages, making clear that is because of security reasons. And I thought the Signal protocol itself would not allow this to happen, so then comes my question: is this actually possible in some way?
Zero files were copied across devices and I am still using the same phone number.
My reasoning was that it would not possible because the decryption keys aren't stored nowhere else, other than my device and Signal Desktop, for example.
Hi,
I have a feeling the answer will be no, but it's been bugging me forever and I hope I'm wrong.
In Vivado, is there a way to set up the waveform display to display (by protocol) decoded signals?E.G. Say I have a single UART out, it would be nice to be able to specify parity, speed, stop bit count etc. and in place of the square waveform see the packet decoded. Same for SPI, I2C etc.
If you've ever used a semi-decent scope with protocol decoding I'm sure you can picture what I'm saying. I'm familiar with protocol instances and transaction display, which is close enough to what I'd like, but even that only seems to work if something is an IP block.
I've always got by adding a decoder to the testbench, but it seems like such an obvious feature for a waveform display, even free stuff like Sigrok Pulseview seems to do a far better job at it than Vivado's GUI.
Thank you
Hi, I'm green when it comes to crypto so sorry if the question is basic but I'm struggling with it.
When we have two devices. One is Alice second one is Bob as always, and we had generated private keys for those users. We did all the 3 DH handshakes and so on. We have now encrypted messages being sent between them and saved encrypted on the database.
The question is:
What will happen and how to deal with a scenario like what happen if Alice broke her phone or buy a new one and create a new private key. How to check if Alice is Alice with a new key and allow her to decrypt the messages and if it is even possible.
I'm creating a chat app that will be mobile and also browser based. With mobile we have not so much problems because the the device stays longer but the browser can be changed a lot and the problem is how to retrieve the history with a new private key.
I'm open to any answer and critique because this can only help me to deliver my users the best product.
Thanks for all answers :)
Hi im searching how the signal protocol is sending from a device to another ?
I dont think its XMPP, but i cant find it if someone can explain it to me, or just help me find some documentation, it would be very nice.
Thanks in advance

I am trying to a convert a previous project that Sloopdog did in adding a Nest to control a single wire AC Comm device with an Arduino. But in my case i would like to create a HA custom Thermostat solely based and controlled via the ESP device. I have successfully got the ESP32 to work with the Arduino code, but what protocol/component do I need to include in my YAML to get this translated into ESPHOME's YAML.
I will only be using the code that matches below. If this protocol can be deciphered there may be a much easier way to implement this thermostat???
Quick snip of the code that runs off a single Digital output pin.
void AC_Turn_on_high_fan() {
digitalWrite(AC_signal_genPIN, LOW); // sets the digital pin AC_signal_genPIN on
delayMicroseconds(1000); // waits for a second
digitalWrite(AC_signal_genPIN, HIGH); // sets the digital pin AC_signal_genPIN off
delayMicroseconds(500); // waits for a second
digitalWrite(AC_signal_genPIN, LOW); // sets the digital pin AC_signal_genPIN on
delayMicroseconds(4000); // waits for a second
digitalWrite(AC_signal_genPIN, HIGH); // sets the digital pin AC_signal_genPIN off
delayMicroseconds(800); // waits for a second
digitalWrite(AC_signal_genPIN, LOW); // sets the digital pin AC_signal_genPIN on
delayMicroseconds(500); // waits for a second
digitalWrite(AC_signal_genPIN, HIGH); // sets the digital pin AC_signal_genPIN off
delayMicroseconds(1000); //3.6 waits for a second
Everything I've read seems to imply it uses MTProto 2.0, but I've heard people say that for secret chats it uses the Signal Protocol. Does anybody know about this? Is the secret chat protocol similar to that of Signals?
r/androidapps requested I cross-post this here...
Session is a cross-platform, anonymous and decentralized messaging application. You don't need a phone number or email address to make an account.
Session uses the Loki Service Node network to route the data, for which the nodes are rewarded with $LOKI. The Loki Network itself is made up of some ~1000 community operated Service Nodes where 44% of the supply is held in the SNs - about US$7.5 million at the moment.
I love Signal, but I don't love the attached phone numbers or central servers, but I know there's a challenge in allowing an altruistic intention over a financial incentive for the node operators - Sybil resistance. By using Loki's Service Node network, the crypto-economics is designed in a way that a bad actor would drive the price exponentially up while trying to accumulate enough Loki to be able to perform any traffic analysis on the routed data.
Think of it as a Signal fork meets a Monero fork meets an incentivized TOR network.

I mostly work with low speed digital signals so I didn't have any problems yet, but just became curious.
How was your experience with various connections like SPI, SWD, JTAG when it comes to PCB routing? How sensitive were they? Do you have any rules or tips to share?
Hi!
Anyone tried reading these sensors directly (raspberry, Arduino, etc)? Is it a digital or analog output?
Furthermore , what does the cabled ISS output?
I read a lot about ppl jacking the serial output on the console, but cant find much on the ISS.
Thanks!
