EDIT: Updated the $platform variable definitions
We don’t currently publish them, but you should be able to easily/reproducibly build them yourself by building only the obs4 binaries within tor-browser-build ( https://git.torproject.org/builders/tor-browser-build.git ) by:
./rbm/rbm build obfs4 --target $flavor --target $platform
where
-
flavor: one of [release,alpha,nightly] -
platform: one of [torbrowser-linux-x86_64,torbrowser-linux-i686,torbrowser-windows-x86_64,torbrowser-windows-i686,torbrowser-osx-x86_64,torbrowser-android-armv7,torbrowser-android-x86,torbrowser-android-x86_64,torbrowser-android-aarch64]
see the Makefile in tor-browser-build root for other invocation examples
This will require you to build a lot of stuff the first time (go, dependencies, compilers, etc) but after this initial pain rbm will reuse any build artifacts that haven’t changed for the next rebuild.
