From 31b9fa4f384115e400c0a49b35730b42d07b6ff6 Mon Sep 17 00:00:00 2001 From: "Lukacs T. Berki" Date: Thu, 7 Apr 2016 10:03:04 +0200 Subject: Add BoringSSL to third_party . As usual, README.md contains reproduction instructions. It would be better to directly use the source tree under `boringssl.googlesource.com`, but for the time being, this will do.
