An #E2EE messaging app unaffected by #ChatControl

* App: https://chat.positive-intentions.com/
* Code: https://github.com/positive-intentions/chat
* Reddit: https://www.reddit.com/r/positive_intentions

How it works: https://positive-intentions.com/docs/projects/chat

TLDR: I'm working on a #P2P messaging #webapp. Webapps are generally not considered secure because of the nature of serving statics over the internet. This is correct, but not a limitation of this project. (#selfhosting options: https://positive-intentions.com/blog/docker-ios-android-desktop).

As a webapp, I can provide the app with zero-installation and no-registration. The app is only using (local-only) browser storage (specifically #indexedDB). So in a P2P interaction, the traditional concept of "the cloud" is just the physical devices connected over #WebRTC. This allows for things like P2P authentication: https://positive-intentions.com/blog/security-privacy-authentication.

Future:
I'm aiming to create the most secure messaging app out there... (more than #Signal, #Simplex, #threema, #session, #deltachat, #bitchat, etc). I know I have a long way to go to get there. The UI is fairly ugly for the average user, but I think the mechanics are working as expected. I think #JavaScript is underrated in what you can do with it. I'm actively investigating improving the #encryption approach further to align to how the Signal protocol works (currently using a #DiffieHellman key-exchange).

Support:
In the age of #ChatControl, I would like to keep this project #opensource, but open-source funding is not working for me. I don't want your donations (but don't let that stop you) because it isn't sustainable for a long-term project. I have so far only experienced grant-funding rejections. I have no idea what I'm doing in trying to get funding for this project, so any support/advice is appreciated. In recognition of the project in its current state not being able to get funding... (sorry) I will have to go #closedsource (which I'd like to avoid because it undermines several #cybersecurity claims I'd like to make). I don't accept collaboration on the project because this would make tough decisions like going closed-source also immoral.

Новый кандидат в односторонние функции для криптографии и PRNG

В мире криптографии и безопасных вычислений постоянно ищутся новые, надёжные математические структуры. Традиционные подходы часто опираются на классические алгебраические группы, но что, если нестандартные операции могут предложить уникальные свойства для построения защищённых систем? В этой статье я хочу предложить вашему вниманию полилинейные функции с линейными сдвигами и рассмотреть их потенциал для обмена ключами и создания криптографических примитивов, таких как хеш-функции и генераторы псевдослучайных чисел.

🥸 Oh, look! Another cryptographic revelation! Diffie-Hellman is dead, long live Elliptic Curve Diffie-Hellman! 🤯 Because what the world definitely needed was more #jargon masquerading as progress. 🧙‍♂️

Алгоритм Diffie-Hellman: Пишем приватный мессенджер на Go

Это продолжение прошлой статьи про данный алгоритм. Где я рассказывал про возможность общения между двумя пользователями без прямого обмена ключом шифрования. Я уже описывал идею создания прозрачного Open-Source мессенджера на основе этого алгоритма и хочу представить вам его самую простую реализацию с примерами кода. Кода будет много...

Recent ships of the human space fleet are equipped with #DiffieHellman-Drives (which enable them to exchange their position with other, far away ships without allowing outsiders to intercept) and #FloydSteinberg shields (which diffuses all incoming attacks).
Interstellar navigation was very easy after all ships computers were programmed with the #Bresenham-Algorithm.
All crew members were trained in all details of the #Kernighan-#Ritchie protocol.
