In the past several weeks I have applied the openssh/openssl updates to

because every  time they turn around they're getting bad-old-cached-key

I've been trying to go through all the known_hosts files manually and
update  them to give my users a break, but it's a tedious nightmare.
Adding to the  complexity is that many of the known_hosts files are
armored (the hostname/ip  address is not in plain text).

Has anyone come up with a way to read all the cached hosts - all the
~/.ssh/known_hosts entries on a system (or at least per user) and fix

Essentially I need some semi-automated way to fix this since I have many
users's connections to fix still (hundreds if not thousands by the time I
do  machines X users X outgoing connections).
