When you go to my site, you will observe since today that it is secure. This means that it is accessed by the https protocol, and a small padlock, or equivalent symbol depending on your browser, is displayed.
I do not know if it’s really useful, because I do not ask you for personal data, and if you want to give me a donation or buy a Pro license, it’s to Paypal or MyCommerce that you will be connected and provide eventually paypal account or credit card information. These sites were in any case already secure.
But it seems that this is now recommended to inspire confidence in Internet users, and also facilitate SEO by Google.
The links that pointed to my site in http remain active, but a redirection will direct them to the site in https. If I appear somewhere in your favorites, you can update the link to https://paulglagla.com/en/.
