Why the Padlock Isn't Good Enough

When you use the internet, your computer has a conversation with a web server for every site you visit. Everything you submit in a form, any data you enter, becomes part of that conversation. The purpose of encryption is to ensure that nobody except you and the server you’re talking to can understand that conversation, because often sensitive information such as usernames and passwords, credit card data, and social security numbers are part of that conversation. Eavesdropping on these digital conversations and harvesting the personal information contained therein has become a profitable industry. But encryption isn’t an on/off switch. It requires careful configuration. In other words, the padlock isn’t always enough.
