What Is Encryption?
Encryption is a mathematical process that transforms a message to conceal its meaning. Encryption is used to protect messages from eavesdropping, tampering, or forgery over the Internet. This Site uses Secure Sockets Layer (SSL) to encrypt personal information transmitted between our server and your browser.
What Is SSL and How Can I Tell That It Is in Effect?
SSL uses public-key encryption using keys of various sizes, 40-, 56-, 128-bit, etc. The larger the key length and number of possible keys, the more difficult it is for unauthorised persons to decrypt or read the message. For example, messages encrypted with a 128-bit key are much more secure than a message encrypted with a 40-bit key.
The size of the key is tied to a specific browser installation. This secure Site only accepts browsers with a minimum encryption strength of 128-bit. The Site provides the maximum level of encryption supported by your browser. When you use this Site at work, only the browsers provided or authorised by your employer should be used.
When you use this Site at home, you can download browsers with 128-bit encryption or higher from either Netscape or Microsoft at no cost other than connection time. The encryption technology in these browsers is subject to U.S. export regulations and U.S. laws and generally may not be exported to certain countries. For more information, visit the browser manufacturer's Web site.
If the URL of a secure document begins with "https://", the "s" indicates a secure channel to the server. Also, when security (SSL) is present, the majority of browsers display a padlock icon, which is closed once a secure channel is established.
