Plugin / Subresource Integrity (SRI) Manager
Meitar MoscovitzDescription
Description
A WordPress plugin for easily adding a Subresource Integrity (SRI) declaration to any third-party content your pages load. The standards-based integrity attribute is a defense-in-depth best practice currently making its way into browsers. This plugin closely tracks the W3C draft.
Currently, the plugin automatically detects any third-party resources (like JavaScript libraries) and will make a SHA-256 hash of the content. It remembers this hash (until you uninstall the plugin or delete the hash from the admin interface), and modifies your page’s <script> and <link> elements on-the-fly. This way, your visitor’s Web browsers can automatically ensure that the specific library you’re using is the one they’re loading.
Using this plugin can dramatically reduce the liklihood that visitors to your site will be strong-armed into participating in an HTTP DDoS attack. For more information, see “An introduction to JavaScript-based DDoS” by Nick Sullivan.
Future versions of this plugin will also provide an easy-to-use interface for site administrators to maintain a customized list of resource hashes, and to trigger on-demand integrity checks of these resources.
This plugin is still somewhat skeletal. Feature requests and patches are welcome! Please provide a test case with your patch. See the tests subdirectory for unit tests.
If you like this plugin, please consider making a donation for your use of the plugin, purchasing one of Meitar’s web development books or, better yet, contributing directly to Meitar’s Cyberbusking fund. (Publishing royalties ain’t exactly the lucrative income it used to be, y’know?) Your support is appreciated!
