These patches add support for client certificates to alpm and pacman.
This can already be achieved currently by setting an XferCommand,
but doing so significantly reduces the quality of the feedback pacman
gives during the downloads. Especially annoying are the 404 errors on
most database signature files, but that's not the only issue.
I admit this is a bit of an edge case, but I find myself in the
situation where I have to download packages from a private repository
that requires a valid client certificate. I really want the nice regular
pacman feedback back though, so I figured I'd hack it in myself.
I tried to follow naming schemes and other conventions the best I could,
but please let me know if I should change anything, or forgot something.
