# REQRYPT

ReQrypt is a tool for tunneling and encrypting web browser requests to hide

them from local (e.g. router-level, or ISP-level) snooping and interception.

ReQrypt is useful for bypassing ISP-level URL censorship/filtering/logging

systems.

ReQrypt works very differently than other bypassing methods.  ReQrypt is based

on a technology known as "triangular routing".  In a nutshell, ReQrypt works

like this:

    (1) Tunneled request      +----------------+      (2) Forwarded request

               +------------->| ReQrypt server |-------------+

               |              +----------------+             |

               |                                             |

               |                                             V

       +----------------+                             +----------------+

       | PC web browser |<----------------------------|   Web server   |

       +----------------+                             +----------------+

                            (3) Web-page response

Basically:

1. Your web browser issues a HTTP request to the web-server, which is

   encrypted and tunnelled to a ReQrypt server.

2. The ReQrypt server decrypts the tunneled packet, and forwards it to the

   web-server.

3. The web-server responds the HTTP request as if it came directly from your

   computer, and the web page response is sent back via the normal route.

Ordinarily, the HTTP request is sent directly to the web server, unencrypted.

This means it may be read and/or intercepted by a local eavesdropper, such as

your ISP, workplace, or shared family router.  However, with ReQrypt the

outgoing HTTP requests are encrypted and tunneled, rendering them unreadable

to any local eavesdropper.

ReQrypt is effective against systems that only attack outbound HTTP requests

only, and ignore inbound HTTP responses.  Such systems are very common is

ISP-level censorship and logging systems, since processing URL traffic (HTTP

requests) is significantly easier than processing web page responses.

Finally, unlike proxies, VPNs, Tor, etc., ReQrypt is not an anonymity tool.

It does not change the IP address of the tunneled packet.  This can be a good

thing: it means the web responses are sent directly to your PC which means

ReQrypt is typically faster than these other systems.
