What is SSL

Secure Socket Layer (SSL): â€œSSL is the service for security of the content which is being transfer from on end to another end on the internetâ€.
I have justified the SSL as below:
The Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL uses a program layer located between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of the Internet Explorer, Netscape Navigator or Moizlla FireFox browser. The "sockets" part of the term refers to the sockets method of passing data back and forth between a client and a server program in a network or between program layers in the same computer. SSL uses the public-and-private key encryption system from RSA (Algorithm method), which also includes the use of a digital certificate.
Types & Feature of SSL:
Basically, there are two type of SSL being run in the internet. First one is Simple SSL. The Simple SSL certificate is used once for only one domain i.e. If you purchase one Simple SSL that can be use once for https://domainname.com. The Second one is Wildcard SSL, which can be used for multiple domains for the same domain i.e. https://domainname.com, https://test.domainname.com, https://shopping.domainname.com.
Advantage of SSL
~Working on Private Key RSA encryption so if it hacks while transporting on the internet
It will not be decryption by the hacker.
~128-bit or 256-bit SSL encryption level is standard now a day
~Authentication between web browsers and web servers, as well as server-to-server
~Trusted by almost all browsers.
Symbol of SSL:
When you browse any site with https https://domainname.com; you will find a lock symbol at the right bottom of the browser:
By clicking on the lock you will find the following screen to view certificate:
If you want to check/test whether SSL Certificate is installed on the site or not, you can write URL: https://domainname.com
You will be getting the Security Alert Screen as follow:
The 3rd option shows that â€œThe Name of the Security Certificate is invalid or does not match the name of the siteâ€, so you can consider that security certificate is not installed on the site.
If SSL expired on the site, at the same time if you are trying to access the site, you will be getting the following screen;
It shows 2nd option that the security certificate has expired and is not valid further.
ConclusionTo secure your all the important transaction like Credit Card Payment, Online Payment for the bills and etc, you have to use SSL. We do provide SSL certificates, kindly visit the below mentioned URL to obtain more information on it:
