Github Pages: Let's Encrypt!

github-pages-https-lets-encrypt.md

Please petition Github to support HTTPS on github pages: https://github.com/contact

Here's what I wrote:

Obviously, a lot of people want HTTPS for github pages:

• isaacs/github#156

Until recently, that would be difficult to implement but, as it turns out, the implementation is pretty much complete:

• https://letsencrypt.org
• https://github.com/letsencrypt/lets-encrypt-preview
• https://github.com/letsencrypt/node-acme

I'm a freelancer, so I've got time and I'd love to help out in any way I can (I'd even come work for you at a substandard rate) if we could get this implemented by Let's Encrypt launch day.

You can also send a message to support@github.com

@dblock I think these instructions only make sense when you are part of the roll-out as far as I see - for a moment I thought there might be a trick you found to force this ;-)

I changed the CNAME for my apex domain, https://dblock.org to sni.github.map.fastly.net, but that doesn't seem to be serving a dblock.org cert for https for dblock.org. I wonder whether there will be a solution for that? Also whether HSTS is going to be enforceable.

@dblock:

• jonwillia.ms works for me if I put it in /etc/hosts (I’m waiting for DNS to propagate) and hit reload in Safari
• I see the correct (“sni" endpoint) ip for dblock.org
• dblock.org does NOT work for me if I put it in /etc/hosts; github serves the plain github cert.
• dblock.org also has an ipv6 address; I have it turned off in my network stack (just a data point)
• Perhaps github checks the DNS configuration on push to determine which cert to present during SNI and caches it. Since I'm doing this today & dblock's repo was pushed 5 days ago, perhaps you encountered older logic. Try pushing?

I also noticed today, that this is already working for one of my (new) domains: https://twitter.com/stefan2904/status/983469050696257537

FTR - I added jan.wildeboer.net as my custom domain name last friday (2018-04-20) and after about an hour I noticed that a letsencrypt certificate had been automagically added and configured. I could switch my .github.io repo to "enforce HTTPS". So it seems they are doing a soft roll-out (for all? A/B testing?) and I expect an official announcement in the next few weeks.

HTTPS is now officially supported on custom domains!
