[ic] Still need help on setting encryption

[Cliff Browning]

I have read all I can find on setting up gnupg keys for credit cards but am 
still unable to make it work.  I have attempted to upload the pubring and 
also tried pasting the armor file in the pgp set up page. Some of you keep 
telling me to point the GNUPGHOME environment variable to it (preferably in 
the init/wrapper script for Interchange):  which is all well and good except 
where do you find GNUPGHOME variable  or environment and where is the 
init/wrapper.   Have put the path in variable Encryption, set the public key 
in PGP_KEY but get with both I get an error  inappropriate ioctl for device. 
Clear those and no error but no encryption either.    I just need some 
information that a dumb novice can understand on setting up the gnupg public 
key to work with Interchange Credit Card processing.  I set the pubring.gpg 
in what I thought was the home directory but obviously I don't even know 
where that is.  Before public_html , after public_html, in   /cart    or 
/cgi-bin none seem to be where the program is looking.
