I'm still a bit unclear about the following points, perhaps the privacy
gurus here can explain.

1) What is the major difference between JAP and TOR? Is it merely that
Tor is a socks proxy that allows a suitably "sockified" app to connect
with it, while JAP is strictly for HTTP only?

2) When you sockify a app and run it through TOR , your isp is hidden
from whatever you connect to right? But what about your ISP? Can it see
where you are connecting to? Or does it merely see you connecting to the
socks proxy?

3)What is tunneling?

4)Stunnel appears to encrypt connections so no-one can see what is being
sent right? How does this interact with Tor or JAP?

Thanks

Is a very interesting and detailed guide on how to use Tor, Privoxy,
Stunnel, Freecap and DCPP.

1. JAP is an HTTP proxy but can handle HTTP, HTTPS and FTP protocols.
It has a limited number of mixes you can connect to so performance can
be slow. The client is written in Java so should run on any system where
a Java Runtime Environment is available. All traffic is encrypted using
128-bit AES. The JAP client may soon be able to connect to Tor servers
(see the comment about JAP at the bottom).

Tor uses SOCKS and has more servers available. It should be able to
handle any application that can be SOCKSified (not just web/file
transfers). Versions are available for Linux/UNIX and Windows but not
others (Apple OSX users may be able to use the FreeBSD version). All
traffic is encrypted using 128-bit AES.

2. Since both Tor and JAP encrypt traffic, all your ISP will able to
see is the encrypted traffic being sent to the first Tor node/JAP mix.

3. Tunneling is using one protocol to carry headers and data for
another - for example you could include file transfer protocol commands
within an HTTP request to allow it to pass through a firewall that only
allowed HTTP. For tunneling to work, it must go to a server that
"unwraps" the protocol at the other end. Tunneling can include
encryption and authentication but does not have to.

4. Stunnel allows you to tunnel network connections within an SSL
(HTTPS) connection providing encryption. It must connect to a stunnel
server which then decrypts the data. It does not provide anonymity on
its own but a network of stunnel servers randomly routing data between
themselves multiple times should give the same level of protection as
Tor or JAP.

1) Can your ISP see where you are connecting to?

2) Can your destination figure out your orginating ip

3) Are the contents you send secure against prying eyes on route?

I'm less concerned with 1, but it's nice to have if possible.

If I use Tor or JAPS I'm automatically assued of 1)+2) no? But it won't
protect the contents from being intercepted between the last mix and the
final destination?

What if I use a simple annoymizer service? Or just Stunnel?

They will be able to see a connection to the first server of JAP or Tor
but not where they connect to in turn - so they will not know the
ultimate destination. Assuming that you are running a firewall, this
should report the same information - as will a netstat command run from
a command prompt window.

> 2) Can your destination figure out your orginating ip

Not from the traffic alone - it will appear to come from the last server
in Tor/JAP. However Java or Javascript can be used to find this
information from your browser (hence the reason for using Proxomitron or
another web filter to stop this). To see what information your browser
reveals, visit a site like BrowserSpy or Leader Network Tools.

It is also possible for a webpage to include Java/Javascript code
designed to cause a browser to make a direct connection bypassing any
proxies. Aside from blocking all Java/Javascript, the best defence
against this is to use your firewall to restrict your browser to
contacting the proxy only.

> 3) Are the contents you send secure against prying eyes on route?

While encrypted, yes. However since the desintation expects unencrypted
traffic, the final stage (between the last Tor/JAP server and the
destination) will be in the clear. For someone to identify it as your
traffic though, they need to monitor every server of Tor/JAP and perform
traffic analysis to link it with your (encrypted) incoming request. The
only groups with these sort of resources are likely to be the TLA
agencies (hence both Tor/JAP warn against relying on their systems for
"strong anonymity"). However to prevent ISP logging or website tracking,
these systems should be more than adequate.

> What if I use a simple annoymizer service? Or just Stunnel?

Since these only involve one intermediate server (rather than a whole
network), traffic analysis is much easier - meaning that they would
offer less anonymity. However (as mentioned above) a network of Stunnel
servers routing connections at random would give equivalent protection
(this is basically how Tor/JAP work).

On JAP back dooring, old discussion but spot on.
