Explanation of Secure Sockets Layer Certificates

Explanation of Secure Sockets Layer Certificates: Every website now includes an SSL certificate to protect consumer information and secure online transactions.

This means that when you visit a website with an SSL Certificate, the information exchanged between your computer and the server is encrypted, making it impossible for anybody else on the network to access it. Encryption safeguards sensitive information such as credit card details, passwords, emails, and so on.


A website with an SSL certificate is distinguished by the presence of a padlock icon next to the URL in the address bar of a browser. It is reasonable to presume that a website with this padlock emblem is secured by an SSL certificate.

What Is the Process of Using SSL Certificates?


An SSL certificate is the internet’s technique of assuring that thieves cannot intercept, read, or manipulate data sent between your browser and servers.


Without an SSL Certificate, data between your site visitors and your server could be intercepted by anyone on the local network. Encryption safeguards sensitive information such as credit card details, passwords, emails, and so on.


Here’s a step-by-step explanation of how SSL certificates function.

1. A server or browser tries to connect to a website protected by SSL certificates.

2. The server or browser asks the web server for “identity.”

3. The web server delivers the browser or server a copy of its SSL certificate.

4. The server or browser verifies the SSL certificate to determine its trustworthiness. If the certificate is valid, it sends a signal to the webserver.

5. The web server then sends a digitally signed acknowledgement, and an SSL encrypted session begins.

6. Encrypted data can now be exchanged among browsers, servers, and web servers.


While the connection between your website, server, and browser appears to be lengthy, it only takes a few milliseconds to complete.


The first half of the URL appears as HTTP before a website is secured with an SSL certificate (which stands for HyperText Transfer Protocol.) Following the installation of an SSL certificate, the first portion of the URL appears as HTTPS, which stands for HyperText Transfer Protocol Secure.


To view information about SSL certificates on a website, click the padlock symbol next to the URL in the browser bar.


The following are typical details to look for in SSL certificates:

The name of the domain to which the certificate was issued

The person, device, or organisation to which the certificate was issued

The particular Certificate Authority that issued it

The certificate’s expiration date


What Is the Purpose of an SSL Certificate?

SSL certificates’ principal function is to protect a user’s data, prevent attackers from building a fake duplicate of the website, and authenticate website ownership.


It is critical that a website protects its users’ data when they enter personal information such as credit card numbers or access confidential material.


SSL certificates reassure consumers that their connection is secure and private and that the website they are visiting is real and safe for them to share sensitive information.


SSL certificates protect the following types of confidential information:

Medical documentation

Discretionary information

Legal documents and contracts

Names, residences, dates of birth, and cellphone numbers are examples of personally identifiable information.

Login information

Financial Data such as transaction and bank account information


SSL Certificate Types


There are six different types of SSL certificates, each with a different level of validation. These are some examples:

Domain Validated Certificates (DVCs) (DV SSL)

Certificates Validated by Organizations (OV SSL)

SSL Certificates with Extended Validation (EV SSL)

SSL Certificates using wildcard characters (WC SSL)

Certificates for Unified Communications (UCC)

SSL certificates with multiple domains (MDC)


Certificates with Domain Validation


Domain validated certificates are a form of SSL certificate that just confirms the domain name (for example, example.com) and does not validate the entity behind it.


Because the entity requesting the certificate has not been vetted, this form of certificate is the cheapest and quickest to put up, but it provides poor levels of encryption and validation.


Certificates Validated by Organizations


Organization verified certificates are used when the requesting organisation has undergone a substantive verification process.

This sort of SSL certificate provides additional validation than domain validated certificates and includes the owner’s information in the SSL certificate (e.g., example.com, Inc.)


SSL Certificates with Extended Validation

The extended verified SSL certificate provides the highest degrees of validation, but it needs extensive processing and is costly to obtain.


This sort of certificate is typically designated for businesses that must demonstrate high levels of trust and security, such as banks.


SSL Certificates using wildcard characters

A wildcard certificate is used when a corporation wants to secure a domain as well as an unlimited number of subdomains using a single certificate.


This certificate is useful if you need to secure a large number of subdomains.


Certificates for Unified Communications

Initially, a unified communications certificate was created to secure Live Communications and Microsoft Exchange servers.


UCCs, also known as Multi-Domain SSL Certificates, allow a single certificate to secure several domains.


These certificates have been organizationally approved and can function as EV SSLs to provide the highest level of assurance via the green address bar.


How to Get an SSL Certificate

SSL certificates can be purchased from a Certificate Authority or from a third party.


The cost of an SSL certificate varies according to the level of protection required and can range from free to hundreds of dollars.


Certificate Authorities may frequently provide certificates for a one-time cost, which is great if your certificate is about to expire.


Third-party providers frequently charge a fee in addition to one-time and monthly expenses.


When determining where to get your certificate, it is critical to understand the distinctions.


The following are the steps to acquiring an SSL certificate

Set up your server and confirm that your WHOIS records are up to date and reflect the information you are sending to the Certificate Authority.

On your server, create a Certificate Signing Request. Most web hosting firms will be able to assist you with this.

Submit your CSR to the Certificate Authority to authenticate the details of your company and website.

Install the certificate that was issued once the approval process was completed.
