A secure connection between a web browser and a web server may be created with the use of a digital certificate known as an SSL certificate (Secure Sockets Layer). SSL certificates are used to safeguard sensitive information, such as online transactions, login information, and personal data, from being intercepted or compromised by bad actors. This protection is achieved by encrypting the information using a private key.
When a user accesses a website that has been protected with an SSL certificate, the user’s web browser will use a public key and a private key to establish an encrypted connection with the server. Any data that is transferred between the browser and the server is encrypted by the SSL certificate. This renders the data unintelligible to anyone who happens to intercept it while it is in transit between the browser and the server.
There are several distinct categories of SSL certificates, the most common of which are domain-validated (DV), organization-validated (OV), and extended-validation (EV) certificates. DV certificates are the simplest and easiest to get, and their sole purpose is to validate that the certificate holder is the rightful owner of the specified domain name. Further verification of the entity that has the domain name, including their actual presence and legal standing, is necessary for the acquisition of an OV certificate. Websites that need a high degree of trust, such as e-commerce sites and financial institutions, employ EV certificates because they provide the greatest level of validation available and are used by such websites.
SSL certificates, in addition to delivering security, let website users feel more confident in the site they are visiting. If a website possesses an SSL certificate, browsers will display a padlock icon next to the website’s address, letting users know that the website is safe and allowing them to continue browsing. A green address bar is displayed by some browsers for websites that have extended validation (EV) certificates. This signifies that the website has been subjected to stringent validation and may be trusted completely.
For those who own websites, obtaining an SSL certificate is becoming an increasingly critical security measure. Warnings are being displayed by many web browsers for websites that do not have SSL certificates. These warnings indicate that the website in question is not secure and discourage people from going there. Moreover, search engines like Google have said that the presence of an SSL certificate is a ranking component in their search algorithms. This indicates that websites that have SSL certificates have a better chance of appearing higher in search results.

Reasons why your website needs an SSL certificate:
1. Security
Providing your website visitors with a sense of safety is one of the primary benefits of having an SSL certificate installed on your domain. Encryption provided by SSL prevents any data passed back and forth between a web browser and a web server from being viewed by unauthorized parties or altered in any way by those with malicious intent. This is of utmost importance for websites like e-commerce platforms and financial institutions that gather sensitive information from site visitors like credit card numbers and social security numbers.
2. Trust
Getting visitors to your website who trust you is much easier if you have an SSL certificate. Visitors to your website are reassured that their personal information is secure and that your website is trustworthy when they notice a padlock icon next to the URL of your site. This has the potential to boost both the reputation of your website and the level of user interaction it receives.
3. Compliance
In certain circumstances, obtaining an SSL certificate could be necessary in order to be in accordance with the legislation or standards that govern the industry. If you accept payments through credit cards on your website, for instance, you may be forced to comply with the Payment Card Industry Data Security Standard (PCI DSS), which mandates the use of SSL encryption. In this case, compliance with the standard is mandatory.
4. Search engine optimisation (SEO)
According to statements made by search engines such as Google, the presence of an SSL certificate is used as a ranking element in their search algorithms. This indicates that websites that have SSL certificates have a better chance of ranking higher in search results than websites that do not have SSL certificates, which might result in greater website traffic as well as more money.
5. Browser Warnings
Warnings displayed by browsers The majority of web browsers now display warnings for websites that do not have SSL certificates. These warnings indicate that the website is not safe and encourage visitors to refrain from accessing it. The presence of an SSL certificate can help prevent the display of these warnings, which in turn can improve the user experience and minimize the number of users who immediately leave the site.
In a nutshell
A Secure Sockets Layer (SSL) certificate is a type of digital certificate that enables a web browser and a web server to form a connection that is both safe and encrypted. SSL certificates assist in developing confidence with website visitors by providing security for online transactions, login information, and other sensitive data. SSL certificates also protect additional sensitive data. When it comes to maintaining a successful website, having an SSL certificate is quickly becoming an essential need in light of the growing significance of maintaining online safety.
