seckit_csp_nonce

Introduction

SecKit CSP Nonce automatically adds Content Security Policy (CSP) nonce attributes to all inline JavaScript on your Drupal site, enabling you to enforce strict CSP policies without blocking legitimate scripts.
The Problem: Modern web security requires Content Security Policy headers to prevent Cross-Site Scripting (XSS) attacks. However, CSP blocks all inline JavaScript by default. While you can use 'unsafe-inline' to allow inline scripts, this defeats the entire purpose of CSP by allowing both legitimate scripts AND malicious injected code.
The Solution: This module automatically generates unique, cryptographically random nonce (number used once) values for each page request and adds them to all inline

tags. The nonce is also included in your site's CSP header, allowing legitimate inline scripts to execute while blocking any injected malicious code.

This module is perfect for site administrators who want to:

• Improve security with strict CSP policies
• Pass security audits and CSP evaluators
• Support Google Tag Manager without unsafe-inline
• Eliminate CSP violations in browser console
• Comply with modern security best practices

No coding required - just install, configure, and your site becomes more secure!
