A few weeks back a comment on a programmers group on Facebook left me wondering about how many Icelandic websites really use HTTPS so I did the only logical thing, spent hours and hours finding out.
I wanted to answer 2 questions with this, which I believe I have.
1: What percentage of .is urls are using HTTPS
2: What Cert authorities are they using.
Those not interested in the method can skip “The Code” section and go straight to the graphs and data
I started by scraping some lists of .is urls and managed to get about 300 urls which I didn’t think was enough. So I ended up paying 5$ or so for a list with 17398 .is urls. Then I got to writing some software to do something with it.
