Whenever any visitor visits to any website, he wants to have a secured access to a website and also want to know that whether the products and the services offered by them are authenticated or not. Therefore Security of your website plays an important role in converting visitors into customers. If you want to provide a secure service to the customer’s then it is required to purchase an SSL Certificate.
From this overview, we come to know that an SSL Certificate is required for the security of your website.
If the visitor sees http://anydomainname.com in the site bar that means the website is not secured. Many of you may be thinking what is HTTP? HTTP is an abbreviation of Hypertext Transfer Protocol. This protocol was designed in early days as a way to communicate between your web browser and a web server. But Since when the sensitive data started getting transferred between the web browser and web server, through the HTTP protocol, the hackers became stronger and a lot of attacks came out. Because whatever kind of data, you may say sensitive data or any finance related data was getting transferred through HTTP, it gets transferred in a plain text form. So a lot of research was done for making Sensitive data like credit card information, login information and a whole bunch of valuable information to be encrypted and also needed to be secured. Thus HTTPS was being used. HTTPS simply makes encryption.
When valuable information is transferring from the browser to the web server then if hackers try to pick up this encrypted data then it is really hard for them to decrypt it. Thus HTTPS means the website is secured.
As everybody knows how to install SSL Certificate by using Control Panel for a particular domain that too easily.
It is somewhat complex to install SSL certificate where there is no control panel only shell access. Let’s hope this blog will help you a lot in this.
The prerequisite before installing SSL is to install some modules like “OpenSSL” and “mod_ssl” which may or may not have been installed on your web server.
The “mod_ssl” module is configured for providing some items of SSL information for the additional variables to the namespace like SSI and CGI. Due to performance reason’s this information is not provided by default. Now the “openssl” is required as a certificate Management tool and also required for various shared libraries for encryption and decryption algorithm and the protocols like DES, RSA, RC4, and SSL. Mostly these modules are already installed on the servers.
You can install the module “mod_ssl” on your Apache web server, it you are using it using following yum command
In centos operating system run following command.

yum install mod_ssl openssl

SSLEngine on
SSLCertificateFile /etc/ssl/yourdomain.com.crt
SSLCertificateKeyFile /etc/ssl/yourdomain.com.key
SSLCACertificateFile /etc/ssl/yourdomain.com.ca
Allow over ride all

Once the SSL installation has been completed, you can access the website securely by changing the URL from HTTP:// to https:// and using port 443.
When the SSL certificate is installed on your website, you can ensure that any information i.e. contact no, credit card no, etc. which you enter is secured and only it can only be seen by the organization which owns the website.
If you take care of these never-ending things you can perform the tasks easily and securely.
