ContentSecurityPolicy

A Swift library for defining Content Security Policy (CSP) header values.


Requirements

  • Swift 4.0+

Installation

Swift Package Manager

Add the ContentSecurityPolicy package to your target dependencies in Package.swift:

import PackageDescription

let package = Package(
  name: "YourProject",
  dependencies: [
    .package(
        url: "https://github.com/ReadEval/ContentSecurityPolicy",
        from: "0.0.1"
    ),
  ]
)

Then run the swift build command to build your project.

Carthage

To use ContentSecurityPolicy in your Xcode project using Carthage, specify it in Cartfile:

github "ReadEval/ContentSecurityPolicy" ~> 0.0.1

Then run the carthage update command to build the framework, and drag the built ContentSecurityPolicy.framework into your Xcode project.

Usage

Create a ContentSecurityPolicy object using the designated initializer; each parameter has a default values, so you can specify only the directives relevant to your use case:

import ContentSecurityPolicy

let csp = ContentSecurityPolicy(
            defaultSrc: [.`self`],
            baseURI: URL(string: "https://readeval.press")!,
            upgradeInsecureRequests: true
          )
csp.policy
// default-src: 'self'; base-uri: https://readeval.press; upgrade-insecure-requests

You can use the computed policy property value to set the "Content-Security-Policy" header on HTTP response headers. Here's how you might do this using Vapor:

import Vapor

let response = response ...
response.headers["Content-Security-Policy"] = csp.policy
