+# Valid certificate SSL 
+# Pattern attributes: good notsofast notsofast subset
+# Protocol groups: secure ietf_proposed_standard
+# Wiki: http://www.protocolinfo.org/wiki/SSL
+
+# This matches anything claiming to use a valid certificate from a well 
+# known certificate authority.
+#
+# This is a subset of ssl, so it needs to come first to match.
+#
+# Note that opening a website that has a valid certificate will 
+# open one connection that matches this and many ssl connections that
+# only match the ssl pattern.  Thus, this pattern may not be very useful.
+#
+# This pattern is believed match only the above, but may not match all
+# of it.
+#
+# the certificate authority info is sent in quasi plain text, if it matches 
+# a well known certificate authority then we will assume it is a 
+# web/imaps/etc server. Other ssl may be good too, but it should fall under 
+# a different rule
