Encryption

Encryption refers to the technology that protects your communications from being read by unwanted third parties. It scrambles the text of messages when you send them; they can then only be unscrambled by their intended recipient. Many government agencies and rogue groups eavesdrop on messages as they are transmitted across the Internet. Encryption ensures that whatever they pick up is unreadable to them, because they are not its authorized recipient.
