PGP would be an ideal solution for this. The webserver would have the public
key and the people operating the PDQ machine the private key. A few things
to remember are.

1. Call PGP using exec()
2. Make sure you read the PGP docs to see how to use a particular keyring.
3. Make sure the keyrings and randseed files are readable by the apache
user.
4. Have fun

I have successfully got this working and if you need any help let me know

Regards

Subject: [PHP] PHP and RSA/Java (Repost with correct e-mail!)


Hi all,
    I need to use a public/private key encryption system for dredit card
details on a site I am developing.  We are not taking Credit Card payments
with an online marchanmt such as NetBanx Sec Pay, etc, etc, but we need to
send the CC details to the Shop Management for putting through a PDQ
machine.  How can I use a Public Private key system to do this from PHP.  I
know Java can support RSA (although never investigated it), and that PHP can
use standard Java classes (is this true?).

Please any help would be great

Martin Gunther
