GNU Privacy Guard Plug-in (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. And please refer to "Tips - encryption mail" about tips of using BkGnuPG.
Besides I am using confirmation only in the following platform, because there is not developmental environment, although I think that it has no problem if B2 and Win32 version GnuPG are using.
In the case that I am not able to use it well in the platform other than the above Please report situation (OS of the kind/versions, errors of OS and application, etc.) as in detail as possible. Please refer to it "Support about" about the address of the author.
Please confirm that the installation of B2 and GnuPG are completing first of all. I recommend that does the following setting about GnuPG, especially.
Please see the README.W32 file that comes in the GnuPG zip file about these setting method.
