--- title: Securing your GitHub Pages site with HTTPS intro: 'HTTPS adds a layer of encryption that prevents others from snooping on or tampering with traffic to your site. You can enforce HTTPS for your {{ site.data.variables.product.prodname_pages }} site to transparently redirect all HTTP requests to HTTPS.' product: '{{ site.data.reusables.gated-features.pages }}' redirect_from: - /articles/securing-your-github-pages-site-with-https versions: free-pro-team: '*' --- People with admin permissions for a repository can enforce HTTPS for a {{ site.data.variables.product.prodname_pages }} site. ### About HTTPS and {{ site.data.variables.product.prodname_pages }} All {{ site.data.variables.product.prodname_pages }} sites, including sites that are correctly configured with a custom domain, support HTTPS and HTTPS enforcement. For more information about custom domains, see "[About custom domains and {{ site.data.variables.product.prodname_pages }}](/articles/about-custom-domains-and-github-pages)" and "[Troubleshooting custom domains and {{ site.data.variables.product.prodname_pages }}](/articles/troubleshooting-custom-domains-and-github-pages#https-errors)." HTTPS enforcement is required for {{ site.data.variables.product.prodname_pages }} sites using a `github.io` domain that were created after June 15, 2016. If you created your site before June 15, 2016, you can manually enable HTTPS enforcement. {{ site.data.reusables.pages.no_sensitive_data_pages }} {{ site.data.reusables.pages.private_pages_are_public_warning }} ### Enforcing HTTPS for your {{ site.data.variables.product.prodname_pages }} site {{ site.data.reusables.pages.navigate-site-repo }} {{ site.data.reusables.repositories.sidebar-settings }} 3. Under "{{ site.data.variables.product.prodname_pages }}," select **Enforce HTTPS**. ![Enforce HTTPS checkbox](/assets/images/help/pages/enforce-https-checkbox.png) ### Resolving problems with mixed content If you enable HTTPS for your {{ site.data.variables.product.prodname_pages }} site but your site's HTML still references images, CSS, or JavaScript over HTTP, then your site is serving *mixed content*. Serving mixed content may make your site less secure and cause trouble loading assets. To remove your site's mixed content, make sure all your assets are served over HTTPS by changing `http://` to `https://` in your site's HTML. Assets are commonly found in the following locations: - If your site uses Jekyll, your HTML files will probably be found in the *_layouts* folder. - CSS is usually found in the `` section of your HTML file. - JavaScript is usually found in the `` section or just before the closing `` tag. - Images are often found in the `` section. {% tip %} **Tip:** If you can't find your assets in your site's source files, try searching your site's source files for `http` in your text editor or on {{ site.data.variables.product.product_name }}. {% endtip %} #### Examples of assets referenced in an HTML file | Asset type | HTTP | HTTPS | |:----------:|:-----------------------------------------:|:---------------------------------:| | CSS | `` | `` | JavaScript | `` | `` | Image | `Logo` | `Logo`
