PGP for E-mail encryption

How do I go about this?

Hi,

I've been visiting Webmaster World for about 5 months now, you guys are a BIG help, this is my first post (If I remember correctly).

I have a client that needs to accept credit cards, but doesn't want a payment processor. He wants to get the credit card number via e-mail, and process it himself.

I heard I'm supposed to use PGP to encrypt the e-mail somehow. I'm pretty new to PGP, so I'm not sure how to install it.

Here are a few notes that can help you help me :).

1.) The site is being hosted on IPOWERWEB.com.
2.) I got a free PHP based version of formmail called PGPmail. It uses PGP to encrypt posted values in my form, Except I don't know how to install PGP, because I never used it.

Any help would be appreciated, thanks ahead of time.

Don't respond to the above (unless, you want to anyway), I'm pretty sure I have figured it out. Thanks anyway.
