source? wouldn't that be a license violation?
- pixelschubsi 2mo agoWhatsApp paid WhisperSystems (the previous Signal company) for a commercial license. Same as Google. Dual-licensing their encryption protocol library was their main source of income back then. AFAIK, even today you can fetch the WhatsApp Android apk, extract the zip and do a `strings classes*.dex | grep signal` to find class and package names matching the sources in the signal-protocol-java repository in the Signal GitHub.
