Have you ever wondered why is “https” prefix in the browser’s address bar? It means that an SSL certificate has been implemented on the website. Now you may think what is SSL certificate? SSL Certificate also known as Secure Sockets Layer (SSL) guards communication that is exchanged between a browser and a website/application. For sites enabled with SSL, the browser creates a safe connection with the site’s server.

Why is an SSL certificate necessary?

A website that requests or stores sensitive information from visitors, such as login passwords, private details, or financial data, must have an SSL certificate installed. Without this certificate, the information is delivered in simple text, and therefore it can be intercepted and utilized by hackers.

In addition, search engine optimization value increases with the installation of an SSL. Google has said publicly that it uses SSL encryption as one of the performance parameters. Sites with SSL installed are more likely to be ranked higher in SERPs than those without.

Types of SSL Certificates

The most widely used are as follows:

  • Domain Validated SSL

These are the most basic type of Secure socket Layers certificate. These ensure that the website’s domain name is same as the one shown on the certificate. In most cases, no supporting paperwork is needed to initiate the validation procedure. Smaller commercial websites, as well as personal blogs, might benefit from these type of certificates.

  • Organization Validated SSL

In addition to validating the domain name, a company’s Validated SSL certificate confirms the legitimacy of the company running the website. To complete the validation procedure, the company must give evidence of its existence, such as articles of incorporation. These certificates are ideal for online retailers and other organizations that handle private customer information.

  • Extended Validation SSL

The website’s owner, the legitimacy of the business, and the domain name are all confirmed while installing these types of certificates. The validation procedure is more stringent, so the company is required to offer more evidence of its legitimacy. These type of certificates are ideal for highly secure organizations like banks and other financial institutions.

  • Wildcard SSL

Wildcard SSL certificates are a type of certificates applicable on multiple subdomains under a common certificate. E.g- An SSL wildcard certificate for “abcdef.com” would also secure subdomains “news.abcdef.com” and “blogs.abcdef.com”.

  • Multi Domain SSL

Multi-Domain SSL certificates are a type of certificates applicable on multiple domains under a common certificate. E.g – For a site “abcdef.com” with SSL multi-domain certificate could secure domains “abcdef.org”, and “abcdef.us”.

  • Secure Sockets Layer (SSL) Certificate Setup Instructions

An SSL certificate may be easily installed on a website. To begin, choose a reliable certificate authority (CA) and acquire an SSL certificate from them. E.g – Cloudflare.

You may install a secure socket layer (SSL) certificate on a website on your own, or you may contact a developer for the same.
