Is it possible to use HTTPS/SSL on GitHub Pages sites with a custom domain?

问题

Is there any way to use HTTPS/SSL on GitHub Pages sites that use a custom domain? SSL is recommended for better search engine ranking and there are a lot of other uses for it beyond that.

回答1:

SSL is supported by GitHub on sites using a *.github.io domain: https://help.github.com/articles/securing-your-github-pages-site-with-https/

I recommend registering with Cloudflare DNS so that you can set HTTPS up properly for a site on a custom domain, see Cloudflare's blog post for more info: https://blog.cloudflare.com/secure-and-fast-github-pages-with-cloudflare/

Update (5/5/2018) SSL is now supported on custom domains: https://blog.github.com/2018-05-01-github-pages-custom-domains-https/

1. Just go to https://github.com/username/repo/settings
2. Check the below checkbox:

If you are using CNAME or ALIAS records for your custom domain, you’re all set and your site should be accessible over HTTPS.

If you are using A records, you must update your site’s DNS records with new IP addresses. Please see our guide to setting up your custom domain with Pages and update any A records you might have set.

Once you have HTTPS working:

You can optionally “Enforce HTTPS” for your domain in your repository’s settings, ensuring users who request your site over HTTP are upgraded to HTTPS.
