PGP / PKI email encryption

If you are unable to install PGP on your server and are willing to use a single-passcode encryption solution, you can always use one of the built-in CF strong encryption standards (AES, perhaps) and then come up with a solution for decrypting the AES data on the client side.

I think you are going to need to install PGP on the server, or some CFX or Java libraries (basically the same thing). I think CF8 has the hooks built in for PGP but it requires additional licensing and most likely, your hosting provider has not purchased these (it's a fairly heafty investment).

You did not give much details into why your emailing cc info but you may want to research tokenization technologies as some of these would eliminate the need for PGP -- tokens do not need to be encrypted and emailing them is not a security concern. We offer our i4Go product which tokenizes the cc information before your site sees it -- your site only sees the token, card type and expiration date. All this information can be emailed and the recipient can use this information to authorize and post payments. Our solution requires the later functions use our gateway services, other tokenization options will probably have the same restrictions. Check around.

Hope this helps. Good luck.
