Today we will talk about three things:
What Are SSL Certificates?
An SSL certificate is a digital certificate that authenticates a website’s identity and enables an encrypted connection.
What does SSL stands for?
SSL means Secure Sockets Layer. Its a security protocol that creates an encrypted link or buffer between a web server such as GoDaddy or SiteGround Or Namescheap and a web browser on your computer.
To secure your online transactions done on the web, companies and organizations must add SSL certificates to their websites to secure online transactions. By securing their websites the businesses can keep customer information private and secure.
The main purpose of an SSL certificate to keeping the connections secure which then prevents criminals from reading or modifying information that gets transferred between two systems on the web. When you see a padlock icon next to the URL in the address bar, that means SSL protects the website you are visiting. An unlock padlock means the website isn’t secure
SSL certification has been around for the last 25 years or more. However, all of which at some point ran into security troubles. A revamped and renamed version followed — TLS (Transport Layer Security), which is still in use today. However, the initials SSL stuck, so the new version of the protocol is still usually called by the old name.
Different Types Of SSL Certificates
There are different types of SSL certificates with different validation levels.
The six main types are:
- Extended Validation certificates (EV SSL)
- Organization Validated certificates (OV SSL)
- Domain Validated certificates (DV SSL)
- Wildcard SSL certificates
- Multi-Domain SSL certificates (MDC)
- Unified Communications Certificates (UCC)
Why SSL Security Is Important
Here are few reasons why we need SSL certificates for websites:
- Helps to keep data on website secure,
- Prevents hackers creating fake versions of your site
- Helps convey trust to your visitors
- Helps verify the ownership of the site.
Websites that have HTTPS have their traffic encrypted by SSL. HTTPS is the secure form of HTTP.

How do SSL certificates work? We Explain This Here
Information passing between websites are made next to impossible to read when using SSL.
Encryption algorithms are used to scramble electronic data while in transit between computers, which prevents hackers from being able to read the data as it is sent over the internet connection. Potentially sensitive information such as names, addresses, credit card numbers, or other financial details are some of the data that gets protected.
The process works like this:
A browser or server attempts to connect to a website (i.e., a web server) secured with SSL.
The browser or server requests that the web server identifies itself.
The web server sends the browser or server a copy of its SSL certificate in response.
The browser or server checks to see whether it trusts the SSL certificate. If it does, it signals this to the webserver.
The web server then returns a digitally signed acknowledgment to start an SSL encrypted session.
Encrypted data is shared between the browser or server and the webserver.
What is an SSL Handshake?
This process is sometimes referred to as an “SSL handshake.” This may appear as a very long process but happens in milliseconds.
Have you noticed website with HTTPS as part of the URL? Website with an SSL certificates security have the HTTPS before the domain name.
The acronym HTTPS stands for HyperText Transfer Protocol Secure. A website without an SSL certificate will only have the letters HTTP. The “S” is missing. The “S” stands for secure. A padlock icon will also display in the URL address bar showing the website can be trusted and is secure to people visiting the website.
How to view the SSL certificate details?
To view an SSL certificate’s details, you can click on the padlock symbol located within the browser bar. Details typically included within SSL certificates include:
- The domain name that the certificate was issued for
- Which person, organization, or device it was issued to
- Which Certificate Authority issued it
- The Certificate Authority’s digital signature
- Any Associated subdomains
- The certificate’s issue date
- The certificate expiry date
- The public key (the private key is not revealed)
