## Beskrivelse

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](https://blog.cloudflare.com/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.

## Installation

 1. Upload the unzipped `wp-sri` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.

## FAQ

### WP-SRI breaks my plugin/theme. How can I prevent it from blocking my assets?

If you’re a site administrator, you can manually exclude specific resources by their
URL from the Subresource Integrity Manager screen under Tools → Subresource Integrity
Manager.

If you’re a plugin or theme author, you can use the `option_wp_sri_excluded_hashes`
filter hook to dynamically whitelist assets. Please only do this for assets that
are truly personalized, that is, only for assets whose URL is always the same but
whose content is different for each user or page load.

For example, to ensure that the URL at `https://example.com/personalized_content`
is never checked for integrity with SRI attributes, use the following PHP code:

    ```
    function example_never_add_integrity_checking( $items ) {
        $items[] = 'https://example.com/personalized_content';
        return $items;
    }
    add_action( 'option_wp_sri_excluded_hashes', 'example_never_add_integrity_checking' );
    ```

Plugin doesn’t appear to do anything/work on any of my Wordpress 6 installations.
I have been testing with Mozzilla’s observatory.

in the age of page-caching (wp-super-cache) and minification/consolidation of scripts/
styles (autoptimization), this probably needs to be hooked in after all that gets
done otherwise the hash generated won’t match. Ideally, this tests the consolidated
minimized script locally even before it gets uploaded to the CDN to cover the pathological
case that the script gets mutated at the CDN even before it gets it’s SHA hash done.

The plugin works as advertised, out of the box. Kudos to the developers. It would
be smart to update the compatibility info, Tested up to:…

Using the Plug in Yoco Payment Gateway by Yoco for credit cards and this plug in
prevents Yoco from poping up and then redirects to the confirm order page like if
it was an EFT when customer make payment via card. This prevents card payments. 
So I disabled it. This worked but im not sacrificing a function to kill revenue.
There must be another way had another way just cant remember what the htaccess code
was for this.

## Ændringslog

#### Version 0.4.0

 * Stricter parsing for stylesheet tags; the `filterTag` function now requires a
   third parameter.

#### Version 0.3.0

 * [Feature](https://wordpress.org/support/topic/breaks-google-fonts?replies=2):
   Add ability to exclude URLs. Useful when SRI attributes block personalized assets.

#### Version 0.2.2

 * [Bugfix](https://github.com/fabacab/wp-sri/issues/1): Load plugin `textdomain`
   files to prepare for translation.

#### Version 0.2.1

 * Add the `crossorigin="anonymous"` attribute/value pair to modified elements to
   enable Firefox 43’s handling of integrity checks.

#### Version 0.2

 * Feature: A simple administrative interface can be found under the “Subresource
   Integrity Manager” option in your WordPress Tools menu. This interface allows
   you to view the URL and hash pairs currently known by your site, and to delete
   them. Deleting a known hash will cause WordPress to refetch and rehash the resource
   when it is next requested.

#### Version 0.1
