In this post, I’m going to explain the various types of SSL/TLS certificates and under which conditions should you use one for your website.
TLS or the Transport Layer Security protocol is the modern version of SSL or Secure Sockets Layer. It helps in securing communication across servers and user-agents in a computer network.
The most common user-agent is the web browser you’re using right now to read this post.
So, when you see a Secure Green Padlock with HTTPS beside the website address, then every communication between the website and its server is encrypted using algorithms like DSA, RSA, or ECC. I’m not going to explain these cryptographic algorithms here, but maybe explain them in a different post in the future.
