What is an SSL Certificate?

Let us start with the basics. The most common layman’s understanding of what an SSL certificate is that it is the one tasked with triggering that padlock icon at the top of the address bar. SSL (Secure Socket Layer) is a security protocol, which allows for the encryption of data in transit. SSL certificates play two very critical roles.

The first role is the data encryption role. SSL certificates encrypt all the data and communication in transit ensuring that no unauthorized party can access the information. Only those with the key can be granted access to the data. This is how data integrity and data privacy are attained- by using SSL encryption so that any intruder will find it extremely difficult to access the data. 

SSL certificates are also tasked with authentication and verification roles. SSL certificates will provide clear details about the validity and identity of a person, company, or website. By clicking on the padlock on your website, your website visitors will be able to know your name, address and other pertinent details relating to your business. SSL certificates are important part of any website.

Those that have an SSL certificate are likely to rank higher than those websites without an SSL certificate. Furthermore, users will be looking for it to trust you. A Google’s Transparency Report reveals that 84.2% of pages that loaded on google chrome in the USA were all served over HTTPS.

This report shows that web users now value web security and will choose HTTPS over HTTP. The ball is in your court. All you need to do to have a share of the huge chunk of website visitors is to install an SSL certificate.

How does an SSL certificate work?

The way you lock and unlock your doors using a key is so relative to how an SSL certificate works. The main purpose of locking the door is to safeguard your valuables. The same way, encrypting all your vital information will help safeguard the information from the many cyber intruders that are available on the internet today. Without the appropriate key, one will not be able to access the information.

Usually, an SSL session will comprise of two keys.  A public key that is primarily used to scramble the information. This is what is referred to as encrypting. The private key will be used to unscramble or decrypt the information into its original format that can be read and deciphered.

SSL certificates will usually be issued by Certificate Authorities. A CA-verified organization will usually acquire an SSL certificate for a specific server or domain. An end-user who uses a browser to navigate into a website with an SSL certificate prompts the occurrence of an SSL handshake. The web visitor will notice changes that indicate that he is browsing over a secure session.

Where to Use an SSL certificate

SSL certificate should be used everywhere where there is need to secure the communication and information in transit. You need an SSL certificate to secure the communication between your servers and the customers’ web browsers. Apart from just securing external information, an SSL certificate will also be of great essence in securing internal communication such as securing internal computation on the company’s intranet. SSL certificates can secure email communication.

Types of SSL certificates

There are three types of SSL certificates which you need to know. You should clearly understand the nature of your organization so that you know which type of SSL certificate is suitable for you. Below are the various types of SSL certificates:

#1 Domain Validated SSL Certificate

This is the standard type of SSL certificate. This type of SSL certificate is usually characterized by low assurance and very minimal encryption. Acquisition of Domain Validated SSL certificate is usually a simple and less detailed process. Just an email or phone conversation is enough to prove domain ownership. It is the cheapest SSL certificate accessible today. The address bar of a website with a Domain Validated will only display the HTTPS status as well as the padlock symbol.

#2 Organization Validated Certificates

The primary role of this type of SSL certificate is to offer the required level of encryption to data transfers. It is also associated with high levels of assurance which are vital when validating the credibility of the organization. Apart from just displaying the HTTPS status and a padlock symbol, this type of SSL certificate will also give detailed information about the owner in the address bar. A substantial validation process is required when completing the acquisition of OV SSL certificate.

#3 Extended Validation Certificate (EV SSL Certificate)

This is the most expensive and the most ranking type of SSL certificate. A website with this type of SSL certificate will display a padlock symbol, HTTPS status, the name of the business as well the country where the business is located. All this information is crucial when a user wants to verify the validity of the business.

#4 Securing Multiple Domains with Multi-domain SSL certificates

Multi-domain SSL certificates are ideal for protecting multiple domains. You do not need to purchase an SSL certificate for every domain. Multi-domains SSL certificate can be of great help when you wish to secure different domains with a single SSL certificate. You, therefore, save money and time by using this type of SSL.

They need to know about SSL functionality and the type of SSL that the site requires.
