Understanding SSL

SSL, short for Secure Sockets Layer, is a type of digital security that allows communication to be encrypted between websites and web browsers. This technology is no longer used and completely replaced by TLS. TLS is Transport Layer Security that secures data privacy, just like SSL does. Because SSL is no longer used, people now call it TLS.

Meanwhile, understanding HTTPS refers to HTTP extensions. Websites that install and activate SSL / TLS certificates can use the HTTPS protocol to make a more secure connection with the server.

  1. SSL / TLS certificates serve to secure sensitive information, such as personal data, payments, or login information, during the transmission process.
  2. SSL / TLS is an alternative choice of ordinary text data transfers where the connection to the server is not encrypted. With this certificate, hackers will be very difficult to penetrate the connection and steal your data.
  3. You could say, most users are familiar with SSL / TLS certificates that are used by webmasters to secure websites and also provide more protection for clients or visitors related to transactions.

The main benefits of using SSL:

  1. Increase the trust of website visitors to make transactions or business with you.
  2. Securing transactions that exist on websites with encryption including credit card data, passwords, etc.
  3. Websites that use SSL / HTTPS get a better SEO ranking than Google compared to websites that are not protected by SSL.
  4. Entitled to display the SSL Secured Seal on the website.
  5. Increase sales or conversion rates on the website as a result of increased consumer confidence.
  6. (EV SSL) Increase your company's prestige with green bars and company names in the browser address bar.
  7. (EV SSL from Symantec) Get free malware scanning and security vulnerability assessment services from Symantec.

How does SSL / TLS work?

Digitally, the way SSL works is to lock the cryptographic key to the company information that you want to identify. Data will also be encrypted properly during the transfer process so that third parties cannot enter and steal sensitive information. Not only the private key and public key, SSL / TLS also has session keys for each unique secure session. When the visitor types the SSL secured URL address into the web browser column or opens a protected page, the browser and web server will make a connection.

During the initial connection, a public key and private key will be used to create a session key, which then encrypts and decrypts the data that is being transferred. This session key will remain valid for a limited time and is only used in certain sessions. You can know whether a website uses SSL or not from a lock icon or green bar that appears above the browser. The icon can be clicked on so you can know who is storing certificate information and also for managing SSL settings.

When and Why is the SSL / TLS Certificate MUST be Activated?

SSL / TLS must be installed at any time when sensitive information, such as usernames and passwords, or payment processes, is being transferred or transferred.

The SSL / TLS certificate is responsible for ensuring that only one person or organization is allowed by the uploader - who can access the data being transferred. Of course this is very important because there are many devices and servers that must be passed by information before finally arriving at the 'destination'.

There are three main reasons why you should enable SSL / TLS on the website:

  1. You need authentication. Any server can pretend to be your server, stealing all information sent through your website. Here, SSL / TLS allows you to display the identity of the server so that visitors or clients can know who you are.
  2. To gain trust. If you are managing an e-cimmerce site or requesting important data from a user, the first thing to do is to build trust. Installing SSL / TLS is a fairly effective way to show all visitors and clients that your website is truly trustworthy.
  3. Comply with the rules set. In some industries and fields, such as finance, you are required to manage and maintain basic security. In addition, there is also a Payment Card Industry (PCI) guide that must be followed if you want the client to enter credit card information via the website. For this reason, one of the conditions that must be met is the use of SSL / TLS certificates.
SSL can be used on almost all devices so it is possible if this certificate is used as a versatile choice in the era of multi-devices. Using SSL has many advantages, especially in terms of time and money. So what are you waiting for?

How is the connection between SSL / TLS n HTTPS?

During setup, you configure an SSL certificate to transmit data using HTTPS. These two technologies help each other and work together so you can't use just one of them.

URLs are preceded by HTTP (Hypertext Transfer Protocol) or HTTPS (Hypertext Transfer Protocol Secure).


At this point, we can draw conclusions about SSL. SSL stands for Secure Sockets Layer (while TLS is short for Transport Layer Security) whose function is to guarantee visitors when they want to send sensitive information to and from the server. SSL encrypts all transferred data so that it cannot be stolen or tapped by third parties, such as hackers and scammers.

Websites that use SSL / TLS can be seen from the green padlock icon in the browser address bar. Click on the icon and you can know clearly who the SSL certificate holder is.

The existence of SSL / TLS has a significant impact on security, search engine optimization, and also affects site rankings or even website performance compared to competitors. As such, it is not only a powerful SEO tool, but SSL / TLS certificates are also needed to increase your site's ranking in search engines.
