SSL encrypts information sent between our website and your web browser so that it cannot be read as it is sent across the internet.
SSL stands for secure sockets layer (you never know, it might come up in a quiz sometime), and it's most commonly used when websites request sensitive information from a visitor, like a password or credit card number.
If you've ever bought anything online, you've probably used SSL without realising it. Most web browsers display a padlock when you're viewing a site over SSL, so you know the connection is secure and we use it on all pages which require you to enter information in our shop.
The address of pages viewed over SSL also normally starts https://, instead of http://.
