OMG!!

First of all, you'd be mis-educating them if telling them that certificate
"validity" has any real meaning. (But now you're talking about http.)

I mean validity as in trusted roots that have been shipped with your OS or
browser. Surely you don't mean these are meaningless. AFAIK they are very
reliable as long as you never accept bogus certs. If you accept bogus
certs "all the time", I really hope you know what you're doing. Pretty
much any important site should have working SSL.

There is a reason why all the browsers freak out when you get a bad cert,
but users still click "add exception". My captive education portal would
give real consequence to this with the 3 minute power point slideshow and
mandatory quiz. I wonder if this is already patented. . .

Second, why do you think you have any right to put speed bumps in the way
of people who are doing nothing to you?

Plenty of businesses do this already for captive portals and forcing users
to log in, pay, or accept an EULA. They are already tampering with your
SSL connection in order to redirect you to the portal. I'm just suggesting
to use this technology for "educational" purposes.

Third, if your grandmother needs internet "safety" education, just educate
her, or refuse to keep fixing the problems she encounters in her ignorance
- if she really is all that ignorant. I hope you wouldn't install a browser
re-direct without her consent, because then you'd be just any other malware
propagator with just any other self-righteous rationalization.

Well, I'm lazy. I'd much rather have an ongoing passive education program
for anyone that uses that router. Maybe only 1 in 1000 requests trigger
the "test", or once a month per mac address maybe. If grandma fails the
test I can get an email so I can call her up and gently chastise her.
"Grandmaaaa, did you accept a bogus SSL certificate again? Hmmm?"

As far as consent goes, I'm only talking about routers you own or have
permission to modify. That should go without saying.

Fourth, if *you *need educational "speed bumps" on *your *router, *you *are
free to have them. One of the great things about freedom - from government
or from meddling busybodies - is that *you *get to be free too.

My post is in the context of businesses or individuals that provide
Internet to the public. Presumably businesses and individuals have the
freedom to do this kind of SSL interception, since they've already been
doing it for years without any repercussions. Personally I'm disturbed
that businesses will try to get me to accept their SSL cert for their Wi-Fi
portal, but I know the technology leaves little choice. One trick is to
ignore the cert and try again with a non SSL address.

It is pretty ironic that the first thing these captive portals ask users to
do is blindly accept a bogus SSL cert. It is really just a sad state of
affairs that we are literally training people to accept bad SSL
certificates.

For years my Firefox has had an option to "always use HTTPS", and I'm sure
all other modern browsers do as well. Plus, Mozilla.org has a free plugin -
I think it's from EFF.org - called "HTTPS Everywhere". It's all very easy
to use, and will be almost entirely transparent to Grandma.

This won't do anything to protect you/grandma from bogus ssl certs.
Imagine connecting to a bad AP at Starbucks that is proxying all your SSL
connections. Your only defense is trusted roots and knowing not to accept
bogus SSL certs. If only we had a captive router-based SSL education
program... ;)

A system like I described would just be an "educational tool" to encourage
people to use HTTPS (properly). It wouldn't stop you from accepting bogus
certificates-- just a speed bump. Now that I've thought about it I'd
really like to install something like this on my grandparent's router. .
. heck, my own router. . .
