HushPOP, which can be downloaded for free from the company's Web site, is a transparent add-on that runs behind a user's desktop e-mail client and takes a unique approach to encrypted e-mail. Like many other secure messaging programs, HushPOP uses an encryption engine to generate unique keys for each user. However, HushPOP keys are generated on each user's local machine. Once a user logs into the program with a private pass-phrase, he or she can send and receive secure e-mails just like any other message.

Once a message is generated, it is sent to HushPOP's key server and then on to the recipient, who doesn't have to have HushPOP installed. Messages are encrypted with 1,024-bit security.
