Hi,

We don't prevent it. The binaries are signed by well known keys of tor packagers and developers. The mirror update script randomly selects a binary and verifies it each time it runs. If the binaries don't match, the mirror is removed from the public list.

Happy to have your help and code in writing some way to verify the totality of files served by each mirror, in some automated fashion.

Thanks!

Subject: [tor-mirrors] mirror content integrity

Hi there,

How do we prevent a mirror admin from tempering with the served files ?
