From 5c404268d965d9ca012e4819ac0c2f289a4c768c Mon Sep 17 00:00:00 2001 From: Allan McRae Date: Sat, 18 Feb 2012 16:31:37 +1000 Subject: Add information on how an installed package was validated When installing a package, store information on which validation method was used and output this on "pacman -Qi" operations. e.g. Validated By : SHA256 Sum Possible values are Unknown, None, MD5 Sum, SHA256 Sum, Signature. Dan: just a few very minor tweaks.
