Server and Linux desktop builds were already reproducible, and Android APKs are now as secure.
Anyone can check it themselves - no coding needed, just follow our simple guide to verify the app is genuine or run the build yourself: https://simplex.chat/reproduce/
A big news for SimpleX Chat app security:
Android APKs released on GitHub and F-Droid are now 100% reproducible!
It means that you can verify that the app is secure, even if the download site was hacked.
From v6.5 our release process is:
1) build Android apps on two independent systems and confirm they are 100% identical;
2) cryptographically "sign" them;
3) add signature files to the release page.
v6.5 beta.3 release: https://github.com/simplex-chat/simplex-chat/releases/tag/v6.5.0-beta.3
If the law is passed, two options are possible:
- we might need to stop offering preset servers to the EU users.
- we will not need to change anything - this is the most likely outcome.
Our operations are always consistent with our Privacy Policy (https://simplex.chat/privacy), and we would rather shut down than do anything that contradicts this agreement with our users. (2/2)
Our users asked many questions about Chat Control, as discussions were restarted in the EU this week.
SimpleX Chat is an open-source app where users control the code and the servers they use.
Therefore it is impossible to implement any client-side scanning, and it will not happen. (1/2)
