GNU Privacy Guard Plug-in for Becky! 2

Japanese | English

BkGnuPG is the plug-in software to be used with Becky! Internet Mail Ver. 2 (B2). By using GNU Privacy Guard (GnuPG) you can sign or encrypt your e-mail message. Also it can verify or decrypt incoming e-mail that was encrypted or signed by Pretty Good Privacy (PGP) or GnuPG.

There is a Becky PGP plug-in (BkPGP) that comes with B2, but almost everything you can do through PGP can be done by GnuPG, and GnuPG supports functions not yet supported by PGP.

BkGnuPG is free software. For further information about the copyright of BkGnuPG, please refer to BkGnuPG\readme_en.txt that comes in the BkGnuPG zip file.

First of all, please download the latest version from the following link.
