From b694d43c5fb4abe41907f38557323446d1e3effb Mon Sep 17 00:00:00 2001 From: Peter Hartmann Date: Tue, 30 Aug 2011 13:10:06 +0200 Subject: QSslCertificate: also check common name for blacklisted certificates ... to reduce the possibility of blacklisting valid certificates that happen to have the same serial number as a blacklisted one, which is unlikely, but possible.
