GnuPG是一款邮件加密工具，多平台下运行并在GPL协议下授权。
GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880. GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. A wealth of frontend applications and libraries are available. Version 2 of GnuPG also provides support for S/MIME.
未经加密的邮件很容易被不怀好意的偷窥者看到。如果对带有敏感信息的邮件进行加密和签名，就可以大大提高安全性。使用GNU Privacy Guard（GnuPG）就可以对邮件进行加密，当然你的邮件客户端也要提供相应的支持，如果你使用的是Mozilla Thunderbird，可以到http://enigmail.mozdev.org去下载Enigmail插件，对于Outlook客户端，也可以找到相应的插件。
