PGP-Related Utilities and Services

Here are some utilities and services that are either PGP-aware or supplement the functionality of PGP in some way. Please send me email if you know of anything I can add to this this list to make it more complete.

Windows Interfaces for PGP

PGP has no graphical user interface (GUI) and must be controlled via an old-fashioned command-line. Here are some Windows front-ends and full-blown Windows applications that have been created to cope with this limitation. The below list is alphabetical, and the ordering of items should not be taken as a comment by me on which tool is better than another.

Scott Hauert maintains a comprehensive list of PGP front ends for Windows. If you don't see something here, check his page.
