Hash: SHA1

If your router is accessible from the WAN port via http then you have
more urgent problems than Heartbleed.

If a site has both http and https then there's no (new) vulnerability
with http, but a Heartbleed attack on https can still extract
passwords and other info.

To extract a password from an http session a bad guy needs to be a
man-in-the-middle, or sniffing the network (remember Firesheep?). To
extract a password with Heartbleed an attacker only has to initiate an
https session.

Don't forget to add Canada Revenue (and most other government
