An acronym for "Secure Sockets Layer", a form of encryption designed by Netscape Communications Corporation to provide secure transmission of data on the Internet. When ssl is employed to secure your transaction, the information contained in your transaction is secretly encoded as it is sent between your computer and the computer (web server) you have linked to. Note, for an ssl transaction to work, your browser must be ssl compatible, and the web server you have linked to must be able to perform the necessary "key exchange" with your ssl compatible browser.
ssl is often used in conjuction with http to create https. https typically runs over port 443. https is used to secure connections between a client and web server. This prevents sensitive information such as credit card and addresses from being passed across the internet as text but instead is passed encrypted.
We offer ssl certificates for our clients as an upgrade option.
