Here on my system:
$ dpkg -l|sed -e'1,/=====/d'|wc -l
$ dpkg -l|sed -e'1,/=====/d'|grep ^ii |wc -l
$ dpkg -l|sed -e'1,/=====/d'|grep -v ^ii

Are you sure you hava all package lines starting with "ii"?
(I know some package may still be lacking *md5sums under some
configuration. If so, I suggest to read debsums and debsums_init
manpages. This issue is solved since 2007.)

gpg is slow. sha variants will be nice if there is smooth transition in
place properly planned and supprted with backported package of debsums.
The advantage of debsums is precalculated sum values and quick sanity
check capability against random changes.
