From 8db4db6563a98c4fac3e833707ab2b14098657d5 Mon Sep 17 00:00:00 2001 From: Lianhao Lu Date: Fri, 22 Nov 2019 10:11:45 +0800 Subject: Support non DOS/Windows format CSAR manifest file When recreating the csar manifest file during signature verification, we should use the same newline charater as the original file instead of using the DOS/Windows newline charater to avoid false positive signature verfication failure.
