This site doesn’t process sensitive data like logins or credit cards, so technically HTTPS is not necessary. But Internet users have come to expect encryption for everything, including browsing a basic informational site like this one. Also, Google adds another incentive: they use HTTPS as a signal for search result rankings. In any case, using HTTPS makes a site look more modern.
I’ve removed all the “mixed content” warnings I could find, but please tell me if you find any. (A page with mixed content won’t have the “padlock” in the browser address bar.) Also tell me if you experience a degradation of performance (I have not).
Please consider changing your links to my site to use HTTPS: https://www.exploringbinary.com/…/. Old HTTP links will redirect to HTTPS, but direct links would be cleaner.
