B Using GnuPG with other e-mail programs

The Gpg4win compendium mainly looks at the Outlook e-mail program. However, GnuPG can also be used with all other e-mail programs. However, there are great differences in user comfort - the better GnuPG is integrated into an e-mail program, the easier it is to use it.

The simplest method, e.g. if an e-mail program does not know anything about GnuPG, is to encrypt using the clipboard, with Kleopatra's assistance. This only works for OpenPGP; for S/MIME and complex PGP/MIME e-mails you will have to use intermediate storage as a file. Both methods are described in the first part of this compendium.

Currently, an integration of GnuPG is offered for the following e-mail programs under Windows:

Thunderbird

with Enigmail⁷.

Outlook as of Version 2003

with GpgOL. GpgOL is a part of the Gpg4win package.

Claws Mail:

This e-mail program is part of the Gpg4win package, and can be optionally installed. Such an installation already configures the program extension for the use of PGP/MIME and S/MIME. This extension however does not use Kleopatra, and therefore does not currently offer the same comfort as offered by the GpgOL Outlook extension.

KMail/Kontact:

KMail and Kontact offer a comfortable and proven integration of GnuPG. They are available for almost all GNU/Linux systems and recently also for Windows and MacOS X.
