Thanks to the great team of TuxFamily.org, free hosting for free people, and taking advantage of Let's Encrypt technology, our site runs since today with full HTTPS support.
You can check the class-A HTTPS certificate at QualysSSLLabs site.
Simple, unencrypted HTTP is still available, because old browsers do not recognize the validity of certificates emitted by the "Let's Encrypt Authority X1".
Anyway, you are encouraged to use HTTPS connections whenever possible. Should you experience any problem, please let us know by leaving a comment below.
