Similarly, PGP makes the actual process of encrypting and decrypting your messages a straightforward process. The client offers seamless integration with Eudora Pro and Light (versions 3.0 and later) and functions as a plug-in for Microsoft Outlook and Exchange. If you use another mail client you can access PGP via either PGPmenu (a context menu plug-in offering clipboard encryption) or PGPtray (clipboard encryption accessible from a system traybar application).
PGP also allows you to encrypt/sign or decrypt/verify files on your desktop directly from the Windows Explorer. File formats that can be used with PGP include Web pages, documents, spreadsheets, sound bytes, video clips, and more.
