cspparse is a tool to evaluate Content Security Policies. It uses Google's API to retrieve the CSP Headers and returns them in ReconJSON format. Not only does it check for headers with Google's API, it also parses the target site's HTML to look for any CSP rules that are specified in the <meta> tag
