A user-specified CSP extension for Chromium.

Content Security Policy (aka "CSP") is a mechanism that allows web developers to control the behavior of browsers, notably disabling many on-by-default capabilities in web pages, such as the ability to request scripts from any other site or to run plugins.
As a developer-facing feature, CSP allows sites to lock-down these capabilities via a policy provided to the browser on a page-by-page basis. This extension allows you, the user, to provide a default policy which is stricter than the browser's default (wide-open) policy, putting the power of CSP in your hands.
It also provides the ability to configure policies on a site-by-site (and eventually, site-type) basis, disabling dangerous features for your banking sites while leaving them on for general browsing.
Contained in this repository you'll find the sources for the Chrome extension, an implementation of CSP in JavaScript, and tests.
This repo pulls in other Git repositories through submodules. After cloning the repo, run:
$ git submodule init
$ git submodule update
...
To run the test from the command line, first, see if they already run without any extra work (they should on most Mac or Linux boxes):
$ cd tests
$ ./run.sh
...
If you get an error like:
$ ./run.sh
FAILED: No JavaScript Runtime Found! Please install Java or the V8 Shell (d8) and add them to your $PATH
Check out a copy of V8, build the "d8" and "shell" targets, and add them to your $PATH.
