Worried that someone is monitoring your E-mail? Here's a free program that encrypts your data, which you can send as an E-mail attachment using any E-mail client. Note: your recipient will also need a copy of Ghostphrase to decrypt your message. Ghostphrase employs three passwords, as well as a mouse-clicked keyboard (which makes it impossible for others to log your keystrokes).
