As always, check the error log. The most common problem is something like:
minivend.com 3Ex5lvta:minivend.com - [01/Sep/1997:09:08:43] simple /cgi-bin/simple > Encryption error: >
Probable causes:
.pgp
or .gnupg
directory in the home directory of the user running MiniVend. It is also possible to set an environment variable (variously
PGPPATH or
GNUPGPATH) to orient the program correctly.
EncryptProgram /usr/bin/pgp -fat -r sales@your.com 2>/dev/null
For GNU Privacy Guard, GPG, you would use something like:
EncryptProgram /usr/local/bin/gpg -fa --always-trust -r sales@your.com On Windows or other operating systems, the only fix is to sign the key or otherwise prevent the error from occurring.
