SSL is a special Internet protocol that uses cryptographic encryption of the data sent to and from your website, so that no-one can decrypt and understand it except your server software. It is used to secure information.

In order to use HTTPS, you need to have a SSL certificate. It's a special data which identifies your server, and tells Internet browsers how to encrypt the data sent to it. The SSL sertificate downloaded from a site is only valid within that site. this Certificate protect the information you send to the website by making sure that only the server can decode it.

Some websites ask you to download a SSL certificate. This certificate helps protecting the users information from being viewed by anyone other than the server itself. It is used in websites that use HTTP protocol for security reasons.

SSL is an acronym for Secure Sockets Layer.SSL creates an encrypted connection between the web server and the visitor allowing for private information to be transmitted without the problems of eavesdropping, data tampering, and in a secured way.To enable SSL on a website, you will need to get an SSL Certificate that identifies you and install it on the server.The use of an SSL certificate on a website is usually indicated by a padlock icon in web browsers, indicated by a green address bar,changing the URL from http:// to https://.Online businesses use SSL certificates to secure their websites and allow their customers to place trust in them.

There are several service providers like http://www.thewebpole.com/ssl/ssl-certificates.aspx?ci=1790&prog_id=456994 where the domain is validated,with best encrypting technologies.

SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers.

SSL Certificates uses a cryptographic system that have a key pair: a public and a private key. These keys work together to establish an encrypted connection. The certificate also contains the identity of the certificate/website owner.

If your site collects credit card information you are required by the Payment Card Industry (PCI) to have an SSL Certificate. If your site has a login section or sends/receives other private information (street address, phone number, health records, etc.), you should use SSL Certificates to protect that data.

To get a certificate, you must create a Certificate Signing Request (CSR) on your server. This CSR creates the private key and a CSR data file that you send to the SSL Certificate issuer (called a Certificate Authority or CA). The CA uses the CSR data file to create a public key to match your private key without compromising the key itself. The CA never sees the private key.

Once you receive the SSL Certificate, you install it on your server. You also install a pair of intermediate certificates that establish the credibility of your SSL Certificate by tying it to your CA’s root certificate. The instructions for installing and testing your certificate will be different depending on your server.
