Thanks. But Karanbir, "commit" is not the problem I'm referring to.
It's the ability to substitute a trojaned, fake repository in between
you and the client, to commit a "man-in-the-m8iddle" attack Valid SSL
certificates, and a clean repoository at git.centos.org: the ability
to verify a particulr "tag" with a GPG tag, particularly a cloned
local working copy with the "tags" from upstream for reference, is
invaluable. Red Hat's, and CentOS's, SRPM repositories avoided this by
having GPG signed SRPM's for reference. The GPG signature chain is
more safely managed and verified, in many ways, than the SSL has been.

I'll take this issue over there.
