A Vapor middleware library for adding security headers to protect against XSS, click-jacking, and other web vulnerabilities.
VaporSecurityHeaders is a middleware library for Vapor web applications that automatically adds security headers to HTTP responses. It helps protect against common web vulnerabilities like cross-site scripting (XSS), click-jacking, and SSL downgrade attacks by configuring headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
Swift developers building web applications with the Vapor framework who need to implement security best practices and protect their applications from common web vulnerabilities.
Developers choose VaporSecurityHeaders because it provides a simple, configurable way to add essential security headers to Vapor apps with sensible defaults, reducing the risk of security misconfigurations and saving time compared to manual header implementation.

Covers essential security headers like Content-Security-Policy, HSTS, and X-Frame-Options, providing protection against XSS, click-jacking, and SSL downgrades as detailed in the README.
Offers pre-configured settings for both web applications and APIs, reducing initial setup time and minimizing security misconfigurations with defaults like 'default-src self'.
Allows detailed Content-Security-Policy configuration with a builder pattern and supports page-specific overrides per route, enabling flexible security policies.
Seamlessly integrates into Vapor's middleware stack with simple code additions in configure.swift, making it accessible for Vapor developers.
Exclusively designed for the Vapor framework, so it cannot be used with other Swift server-side frameworks, limiting its applicability.
May clash with headers set by external services like CDNs or hosting providers, as noted in the README regarding Heroku and reverse proxies, requiring manual adjustments.
While it provides tools, crafting effective Content-Security-Policy rules still demands a deep understanding of security concepts, which can be daunting for beginners.
