Re: [tor-talk] Giving Hidden Services some love

Now why would we use https on top of a Tor Hidden Service?

http://foo.onion is not the same as http://foo.com

The regular internet (clearnet) domains, when used with http, do not
provide any kind of encryption or authentication and are vulnerable to
man in the middle attacks and wiretapping.

.onion Tor Hidden Services _already provide end to end encryption and
authentication_ when used with the default http. They are not
vulnerable to man in the middle attacks or hijacks. On top of this
primary layer of encryption, there are more crypto layers in the Tor
circuits connecting a client to a hidden service.

Maybe the crypto currently used in hidden services is not considered
_very_ strong with nowadays available computing power, but adding an
additional layer of encryption using the commercial CA model seams
like the wrong way to do it. Why? Because facebook did it (they were
the first ones as far as I Know), it means now this is somehow a
requirement?

I encourage the work on new generation hidden services, which will
have better security and better end to end crypto. We do not need
commercial CA's in a Tor hidden services for various reasons,
including but not being limited to the fact that when you purchase a
SSL certificate you leave another money trail and provide details to
make a payment / place an order, hurting the anonymity of a hidden
service. Why would you pay for something which Tor already does, and
even does it better?

P.S. I personally have _way more trust_ in the RSA1024 and SHA1
implementation used in current Tor Hidden Services design than in a
publicly available CA.

Rather than spending time to convince commercial CAs to sign .onion
domains, better spend that time to find sponsors in order to enable
coders and skilled persons to work on next generation hidden services.
