HTTPS is the secure version of HTTP, it makes sure that information sent between your browser to the website you’re viewing is encrypted and can’t be decrypted by any machine or person in between.
Traditionally HTTPS was only used on important sites such as banks or checkout pages in ecommerce websites where your privacy was considered paramount. HTTPS wasn’t broadly used in the early days of the internet as SSL certificates were only available to purchase from a relatively small number of companies, they were expensive and it came with a performance penalty due to the additional work needed for establishing the secure connection and the ongoing encrypt/decrypt process.
In 2010, low single digit percentages of internet traffic were encrypted. By 2015, encrypted traffic was at about 25%. In the following 10 years, the barriers that were holding back adoption have been removed. Thanks to Lets Encrypt, you can get free SSL certificates. Web hosts integrate with Lets Encrypt, automatically issue/re-issue and install the SSL certificates. The original performance penalty has been removed. With HTTP/2 (the second version of the HTTP protocol) which requires HTTPS, websites load dramatically faster. Couple that with a big push from companies like Google, suggesting it is a ranking factor with their algorithm and by 2025 over 90% of all internet traffic is encrypted.
I’m late to the party, but I’m doing my part in switching to HTTPS :P
