SSL/TLS/HTTPS, what is it exactly?

SSL is the precursor if the present TLS (Transport Layer Security) en both are encryption protocols for the security of communication between computers on the internet. It will take care that your data can't be monitored or faked. HTTPS means you visit a website who is using the TLS security. This is also visible in the address bar where you can see a green lock icon. This is especially important for web shops and web sites where you have to login, so your data is safe.


When you save personal data in your web site it is required to use a secured connection, at least here in the Netherlands. I don't know how this is arranged in other countries.

I don't have a web shop, why do I need TLS/HTTPS?

So you don't have a web shop or a web site where sensitive data is stored, why would TLS/HTTPS by interesting for you? It secures the data transfer from your web site to the visitor, no one should have the need to monitor this. There can be many companies or agencies interested in just harvesting data and once maybe is it. And also, it might benefit your ranking.

Google Ranking

In 2014 Google announced it will favour web sites in it’s ranking who use HTTPS in it’s ranking. So getting higher (or not dropping) in the ranks is also possible by using TLS/HTTPS.

Free TLS-certificates!!!

Obtaining a SSL/TLS certificate was not cheap a while ago. Depending on the type of certificate you needed it could costs a lot of money. This all changed when Let’s Encrypt started. This organization (not-for-profit) is backed by a lot of large organizations but also small donators and wants to improve the security on the internet by providing free TLS-certificates.

Lot’s of (good) hosting companies are implementing Let’s Encrypt in their environment so if a website owner wants to get a certificate he or she can do so in a few clicks. At least, it was that easy for me!
