What is a TLS/SSL Certificate, and how It works

TLS/SSL Certificate

In this Knowledge Base you will understand what exactly TLS/SSL is? TLS/SSL Certificate? And what is the working of TLS/SSL encryption?

A brief overview:

You can treat online security in the same way you would approach physical security for your home or corporation, whether you are a person or a company.

It is critical to first comprehend the possible risks and then ensure that you are adequately covered against them.

It is not always easy to keep up with the latest technological developments in the fast-paced world of technology. As a result, it is a good idea to work with a trustworthy Internet security firm.

What is SSL/TLS?

SSL/TLS (Secure Sockets Layer/Transport Layer Security) encrypts data sent between a browser and a server. These protocols provide safeguards against electronic eavesdroppers. This also safeguards sensitive communications (for example, credit card numbers and login information).

What is a TLS/SSL Certificate?

TLS and its predecessor Secure Sockets Layer (SSL) are the most widely used security protocols today, and they are primarily used to perform two functions:

  1. Authentication and verification:
    The TLS/SSL certificate contains information about the authenticity of specific details about a person’s, business’s, or website’s identity, which it will display to visitors on your website when they click on the browser’s padlock symbol or trust mark (e.g., the DigiCert® Secured Seal or Norton Seal powered by DigiCert). The Certificate Authority (CA) that issued the SSL certificate validated all of that information. There are various levels of validation available, which we will discuss later.
  2. Data encryption:
    The TLS/SSL certificate also allows for encryption, which ensures that sensitive information exchanged via the website cannot be intercepted and read by anyone other than the intended recipient. Similarly to how an identity document or passport can only be issued by government officials in the country, a TLS/SSL certificate is most reliable when issued by a trusted Certificate Authority (CA). The CA must adhere to very strict rules and policies regarding who may or may not be granted a TLS/SSL certificate. Customers, clients, and partners are more likely to trust you if you have a valid TLS/SSL certificate from a reputable CA.

What is the operation of TLS/SSL encryption?

Encryption, like trying to open doors with a key, uses keys to lock and unlock your information. You will not be able to “unlock” the data unless you have the secret keys.

Each TLS/SSL session has two keys:

  • The public key is used to encrypt (scramble) data.
  • The private key is used to decrypt (unscramble) the information so that it can be read.

In this way, we have became familiar to TLS/SSL, its Certificate and the encryption process which takes place between the server and the user’s computer.

We hope, we have helped you in understanding what is TLS/SSL certificate and the encryption process. For more such informative tutorials visit bodHOST.
