# Russian Anti-Censorship on PAC-Scripts
|
|
|
|
This repo contains:
|
|
|
|
1. Chrome Extension to bypass censorship in Russia:
|
|
[WebStore](https://chrome.google.com/webstore/detail/npgcnondjocldhldegnakemclmfkngch)
|
|
| [Sources](https://github.com/ilyaigpetrov/anti-censorship-russia/tree/master/extensions/chromium/minimalistic-pac-setter)
|
|
2. Proof of concept PAC-script generator based on https://github.com/zapret-info/z-i
|
|
3. ~~PAC-scripts performance analyses of scripts generated~~ (doesn't take parse time into account)
|
|
4. Based on the research of step 3 [the final PAC-generator][pac-generator] was written as a Google App Script in JavaScript which is triggered every two hours to generate and publish PAC-script on Google Drive (don't use direct URL without extension, please, URL will be periodically changed to counter abuse).

## Why I do This
|
|
|
|
I believe __information mustn't be blocked based on political or other subjective views__.
|
|
|
|
My maxim is _"Your freedom ends when it starts to confine the freedom of others"_.
|
|
|
|

Looking at how Russian government [distorts TV](https://therussianreader.wordpress.com/2015/11/22/russian-truckers-strike-dagestan/) and blocks [critics of Putin](http://www.reuters.com/article/2014/03/13/us-russia-internet-idUSBREA2C21L20140313),
|
|
I decided to write an anti-censorship extension for Chromium before they strike me first.
|
|
|
|
## How it Works
|
|
|
|
0. PAC script is a JavaScript file, triggered on every URL request, which says browser which proxy to use if any for this particular URL.
|
|
1. The Chrome Extension sets PAC script in browser settings and keeps it synced with PAC script on the server (offering Antizapret (hosted on a dedicated server) or Anticensority (hosted on GitHub + CloudFlare)).
|
|
2. On every request PAC script checks if host is blocked or if its IP is blocked.
|
|
3. If address is blocked PAC script returns proxy server to the browser, both Antizapret and Anticensority use Antizapret proxy servers.
|
|
4. PAC scripts on servers are updated periodically from https://github.com/zapret-info/z-i.
