Re: Reproducing distributed binaries
Well, we publish the rpm spec file so you can build your own rpm here:
http://tor.eff.org/cvs/tor/tor.spec.in which is also in the source
Feel free to submit the trivial script to do as you suggest below, we'll accept it.
The binary releases are also signed with the developer's key. Such as
