What is an SSL certificate?

If you've come across an SSL certificate online and don't know what it means, then this article is for you. Here you'll learn everything you need to know about SSL certificates.

The need to maintain a secure cyberspace is increasing every day because cyberattacks must be avoided at all costs.

There are many programs designed to protect our online activities, and some of them include antivirus programs, VPNs, proxy services, SSL certificates, ad blockers, etc.

Today, we will introduce you to SSL Certificates and other important information you should know about them.

SSL stands for Secure Sockets Layer. It is a type of protocol created in the early 90s with the goal of providing a secure communication path within the connection between two computers.

This ensures that data transmitted from one channel to another remains intact and prevents unauthorized third parties from accessing it.

In contrast, the SSL Certificate generates a type of key that only authorized individuals can decode and convert into information that can be read correctly.

HTTPS is important for websites because it keeps information private on the internet so criminals can't get hold of it.

Where can I find SSL?

You've certainly seen SSL on the web and haven't even realized it!

When you enter a website and are authenticated using SSL, two things appear in the address bar: a padlock icon (usually at the top of the bar) and the letters HTTPS (before the address, on the right side of the padlock).

You've seen them around, haven't you?

HTTPS is an improved version of untrusted HTTP. The first three letters of the acronym stand for Hypertext Transfer Protocol, and the S in HTTPS stands for Secure, meaning that the site has SSL authentication and is secure for transmitting data and information.

While any website can use SSL to appear authentic and secure, its primary purpose is to protect data during transmission. This is why it's so popular on bank and retail websites, as they need to safeguard sensitive data that other websites don't.

Importance of using an SSL certificate
For businesses and individuals, security is important. It allows access to confidential information without compromising its security. Here are the reasons why an SSL certificate is important:

Uses end-to-end encryption
As explained, the SSL certificate uses end-to-end encryption to ensure that shared information is secure and processes are carried out safely.

We previously discussed the use of a security key pair. These keys are called private and session keys. The private key is the one installed on the server, thus creating the certificate of authenticity.

The session key, on the other hand, is installed on the server and allows only websites and their users to access sensitive information, such as bank details.

Fraud Reduction

Cybercriminals have already attacked thousands of businesses, individuals, and even governments! Hackers steal data, leak information, disrupt operations, and make it difficult for online services to function, eroding public trust.

That's why websites use SSL certificates to provide security and trust to their users. It also prevents cybercriminals from carrying out their attacks.

It provides more payment options for e-commerce
Most credit card operators require online stores to have an SSL certificate in order to receive payment from their customers.

Therefore, those who operate e-commerce websites must invest in security to offer more payment options to their customers. Paying with credit cards is much more convenient for customers than with a bank draft.

SSL certificates provide a level of trust and credibility to your customers, especially if you have an e-commerce structure, the kind that allows people to buy something immediately without clicking through to other pages.

With SSL certificates, it's entirely possible to protect your customers' data and only transmit it when they purchase products. This builds trust for both parties, as the customer feels secure with their purchases and you are protected from any security breaches or theft.

How does an SSL certificate work?

SSL works when a user visits a website that uses it. The browser automatically sends a request to the website for its SSL certificate. When the website responds, the browser evaluates the certificate to ensure it is trustworthy.

If everything is confirmed, the SSL protocol will begin its encrypted activities; thus, two encrypted keys are created: the private key, which is in the browser and is used to interpret the information, and the session key, which encodes the information.

This prevents criminals from accessing the connection and stealing data because it is authenticated by the SSL protocol.

Where can I get an SSL certificate?
If you have a shopping and sales website or any other online business and want an SSL certificate to provide more security and show your customers that your company is trustworthy, you can obtain it through your hosting service.

Most hosting providers offer the option to install SSL on websites that require it. Alternatively, you can obtain a free SSL certificate from a Certificate Authority (CA) such as Let's Encrypt.

Most of the time, you don't need to worry too much about these processes, as they are usually automatic, since the hosting server itself performs the checks, issues the certificate and also installs it.

However, you can choose to buy SSL elsewhere, but you will need to install it yourself, which can be quite complicated if you are inexperienced.

What happens if you don't have an SSL certificate?

If you do not have an SSL Certificate, the following will happen;

You'll experience a drop in traffic: no one will feel comfortable browsing a website that web browsers have labeled as insecure. In fact, HTTPS is one of Google's ranking factors.
It puts website visitors at risk: without an SSL certificate, a website is prone to data interception, which puts both the customer and the business owner at risk.
Negative impact on website ranking in Google: A secure website has always been a ranking factor for Google. Therefore, a website without an SSL certificate tends to rank lower.
Conclusion
Now that you understand what an SSL certificate is and how important it is, don't you think you need one?

Besides adding more value to your company, it also provides more security and makes your customers and users trust you more.
