What is an SSL, and why do I need an SSL certificate?

Even though, with time, Tech companies give more importance to user privacy and security. However, today, most internet users still believe that current laws are not enough to protect their rights.

The SSL certificate is the one that enables the website to redirect from HTTP to HTTPS.

SSL stands for Secure Sockets Layer; it's a security technology that layers a secure connection between a web browser and web server and ensures that data transfer remains private. The SSL Certificate is also called TLS (Transport Layer Security).

You will need to install an SSL certificate on your web server to ensure that the data connection between your web server and web browser remains secure.

An SSL is a file hosted on a website origin server that contains key pair: a public key and private key. These keys work together to create an encrypted connection. The SSL certificate also includes the "subject," which is the identity of the certificate/website owner.

Today, if you want to make your website look legitimate and trustworthy, you want to boost your conversions, sales, leads, revenue, customer loyalty, and satisfaction. It would help if you had an SSL certificate installed on your website's server.

Especially, suppose you have an e-commerce store selling something online that requires user/customer's personal information. In that case, you must have an SSL certificate to protect and encrypt the user's data.

What is an SSL certificate thumbprint?

An SSL certificate thumbprint, also known as an SSL certificate fingerprint, is a hash of a certificate calculated on all certificate's data and its signature.

The thumbprints are usually implemented with cryptographic hash functions. They are generally used as unique identifiers for certificates, configuration files, applications when making trust decisions and displayed in interfaces.

How is SSL certificate fingerprint calculated?

The SSL certificate thumbprint/fingerprint is a digest (hash function) of a certificate in x509 binary format. Different algorithms, such as SHA1 (for Microsoft Internet Explorer), can calculate it.
