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
