Subject: [PATCH 1/3] add collision-detecting sha1 implementation
Date: Thu, 23 Feb 2017 18:05:37 -0500
Message-ID: <20170223230536.tdmtsn46e4lnrimx@sigill.intra.peff.net> (raw)
In-Reply-To: <20170223230507.kuxjqtg3ghcfskc6@sigill.intra.peff.net>

This is pulled straight from:

  https://github.com/cr-marcstevens/sha1collisiondetection

with no modifications yet (though I've pulled in only the
subset of files necessary for Git to use).
