sha1dc: import latest version from github...
sha1dc: import latest version from github After the recent SHA1 news, the attacks are serious enough we should be more proactive. This code will at least allow detection of attacks early. It's already widely deployed in Git. This is git revision 855827c583bc30645ba427885caa40c5b81764d2 of the sha1collisiondetection repo[0], with most of the files omitted. A follow-up change will introduce Python bindings for this code. 0: https://github.com/cr-marcstevens/sha1collisiondetection Differential Revision: https://phab.mercurial-scm.org/D7814
