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.
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 is placed into a
Certificate Signing Request (CSR) - a data file also 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. Your web server will then be able to
establish an encrypted link between the website and your customer's web
browser.
