HTTPS Protocol

What’s the HTTPS protocol?

HTTPS is a secure exten­sion of the HTTP pro­to­col, the “S” for “Secured” means that data exchanged between the user’s brows­er and the web­site are encrypt­ed and can­not be spied on (con­fi­den­tial­i­ty) or tam­pered with (integri­ty). Obtain­ing the sacro­sanct “S” involves acquir­ing and installing an SSL / TLS cer­tifi­cate from a rec­og­nized Cer­ti­fi­ca­tion Author­i­ty. It will dis­play the HTTPS, the green pad­lock and the word “Secure” in the browser’s address bar.

There are three prin­ci­pal authen­ti­ca­tion lev­els for the issue of the cer­tifi­cates allow­ing to dis­play the HTTPS:

  • Domain Val­i­da­tion (DV) con­sid­ered as low authen­ti­ca­tion;
  • Orga­ni­za­tion Val­i­da­tion (OV) with high authen­ti­ca­tion;
  • Extend­ed Val­i­da­tion (EV) with rein­forced authen­ti­ca­tion.

Note: Start­ing July 2018, with the arrival of Chrome 68, all HTTP web­sites will be marked as “Not Secure” and HTTPS web­sites will be marked as “Secure”.
