Although they do not all use PGP, many online e-mail providers are offering Web-based e-mail with security. You can sign up for a free e-mail account and you only need a Web browser to check, send, and manage your e-mail. Many people have used Hotmail, Yahoo! mail, or some similar type of Web-based e-mail service before. Adding secure e-mail to these services is a recent trend, and will no doubt continue.
Yahoo!, LokMail, and HushMail each work differently. Yahoo! provides its e-mail security through a third-party organization. E-mail messages can be sent encrypted to any e-mail address on the Internet. The recipient of the Yahoo! message must go to http://www.SecureDelivery.com to read the encrypted message.
