SSL is stand for (Secure Sockets Layer) protocol and developed by Netscape for transmitting private documents via the Internet. SSL uses a cryptographic system that uses two keys to encrypt data first one is public key known to everyone and a private or secret key known only to the recipient of the message. SSL 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.To be able to create an SSL connection a web server requires an SSL Certificate. When you choose to activate SSL on your web server you will be prompted to complete a number of questions about the identity of your website and your company. Your web server then creates two cryptographic keys Private Key and a Public Key. When using SSL for secure Internet transactions Web server needs an SSL certificate to establish a secure SSL connection.
