Codeforces: Testing HTTPS
By MikeMirzayanov, 7 years ago, translation, In English

Hello, Codeforces!

I offer you also to join testing of HTTPS support. Just visit to https://mirror.codeforces.com/ and start to use the website through HTTPS.

I am aware of some minor issues: mails still refer to the HTTP version of the website, Facebook does not merge likes for HTTP and HTTPS. Have you noticed anything else? Write a comment!

And thanks to Let's Encrypt for the certificates. Now with wildcards!

Oh no, if I needed to connect to some wifi through browser I always typed codeforces as an only http website I know! What will I do now? Will http://mirror.codeforces.com work?

Google adds criteria to the rankings algorithm when it has proven to provide better user experience. HTTPS protects your users’ information and your information from hackers.

    Really easy to do simple cookie sniffing and HTTP Authorization stealing with HTTP sites. With logging in you are being easily hacked. Finally, HTTPS!

This is very good. Security very raise and hacking it almost impossible.

      It's not about hacking on test cases. You can get 100 points on a successful hacking. It's about hacking by hackers. The site is now protected from the outside attacks.

            He is pretending to misinterpret the statement. Clearly Ali_Pi is talking about the HTTPS, but in another context, it could be read like hacking a test case. So jon's comment is funny because it is unexpected, you don't expect someone to think that way

The website with HTTPS loads slower a little bit.

    It is not possible. Mike does not directly hold the contests, and the organizers have their own work other than Codeforces, which indeed is not a source of income for them. It's just a platform of passionate people practicing their hobbies. :p

Maybe it's worth to check loads of the system before making rated round?

    When you log-in and type your password the man-in-the-middle can steal it, because the traffic between you and codeforces is not encrypted.

It would be great if you can configure your server to redirect all HTTP requests to HTTPS. It should be just couple of lines in your server configuration.

When using HTTPS site, there's no feedback about status of submission from server. Like it "Running on test X" and X used to vary, now everything appears to be frozen. Is this intended?
