SSL- Short Secure Socket Layer
SSL, Short for Secure Socket Layer is a protocol for transmitting private documents via the Internet. It’s is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all the 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.
In today’s Internet world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet. 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 – a Private Key and a Public Key.
The Public Key does not need to be secret. And it is placed into a Certificate Signing Request (CSR) – a data file containing your details. You should then submit the CSR. During the SSL Certificate application process, the Certification Authority will validate your details. And issue an SSL Certificate containing your details and allowing you to use SSL. Your web server will match your issued SSL Certificate to your Private Key. Web server will then be able to establish an encrypted link between the website and your customer’s web browser.
Typically an SSL Certificate will contain your domain name, your company name, your address, your city, your state and your country. It will also contain the expiration date of the Certificate and details of the Certification Authority responsible for the issuance of the Certificate.
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.
Why do I need SSL?
If you are transmitting sensitive information on a web site, such as credit card numbers or personal information. You need to secure it with SSL encryption. Customers won’t trust your web site without an SSL certificate. According to Gartner Research, nearly 70 percent of online shoppers have terminated an online order because they did not “trust” the transaction. Customers want to know that you value their security. And are serious about protecting their information. One of the most important components of online business is creating a trusted environment; where potential customers feel confident in making purchases. An SSL certificate and a site seal could stop people from abandoning your website and that means more money for you.
The most important part of an SSL Certificate is that it is digitally signed. Anyone can create a certificate; but browsers only trust certificates that come from an organization on their list of trusted CAs.
