What is an SSL Certificate?

A digital certificate that authenticates the identity of a site and encrypts information sent to the site. When you visit a website with SSL Certificate, the URL will start with https:// instead of http:// . This shows that any data transferred between your browser and the site is encrypted, making it difficult for anyone to intercept and steal your information.

The certificate is issued by a Certificate Authority (CA), a trusted third party that verifies the website owner’s identity. When you purchase a certificate, you must specify the domain name(s) for which you want it to be valid. The CA will then verify that the domain name is associated with a legitimate business or organisation and issue the certificate.

How Does an SSL Work?

SSL certificates are an essential part of online security. They help keep your data safe by creating a secure connection between your computer and the website you’re visiting.

But how do they work?

A certificate is a digital ID card. It contains information about the certificate holder, such as their name and address and the public key needed to create a secure connection.

When you visit a website that uses SSL, your browser will check the certificate against its list of trusted authorities. If it’s valid, the browser will create a secure connection using the public key from the certificate.

This secure connection ensures that all data sent between your computer and the website is encrypted and can’t be read by anyone else. It also helps to verify the website’s identity, which can help protect you from phishing scams and other online threats.

What information does an SSL certificate contain?

The certificate contains the domain name, company name, and country of the website owner and the public key needed to create a secure connection. It also includes information about the expiration date and security strength of the certificate.

How does a website obtain an SSL certificate?

There are several ways to obtain a certificate, but the most common is to use a web hosting company that offers SSL certificates as part of their hosting package. Alternatively, you can purchase a certificate from a CA directly.

When selecting a CA, it is important to choose one that is reputable and has a good reputation. Some well-known CAs include Digicert, Symantec, GoDaddy, and Comodo.

Once you have obtained a certificate, the next step is to install it on your website. This process varies depending on the web hosting company but is generally relatively easy.

Once your certificate is installed, your website will be able to use HTTPS instead of HTTP, providing a more secure browsing experience for your visitors.

Is it possible to get a free SSL certificate?

Yes, it is possible to get a free SSL certificate. However, the process can be a little bit tricky. Different services offer free SSL certificates, but all browsers do not always recognise the certificates. One provider of these is Lets Encrypt

One of the best options for getting a free SSL certificate is the Cloudflare service. Cloudflare offers a variety of features, including free SSL certificates. Most browsers recognize the certificates, and they are easy to set up.

Conclusion

SSL certificates are an essential part of online security and help ensure that users can safely browse the web and interact with their favorite websites. While there are many different types of SSL certificates, they provide a high level of security for users.

In addition, SSL certificates are also essential for e-commerce transactions, as they help protect customers’ personal information.
