Easily integrate Content-Security-Policy headers into your web application, either from a JSON configuration file, or programatically.

CSP Builder was created by [Paragon Initiative Enterprises](https://paragonie.com)as part of our effort to encourage better [application security](https://paragonie.com/service/appsec) practices.

Check out our other [open source projects](https://paragonie.com/projects) too.

There's also a [CSP middleware](https://github.com/geggleto/geggleto-csp-middleware) available that uses this library.
