2-way encryption in using PHP?
=== sorry.... my first post here --- I had originally posted it in the wrong place===
I was particularly interested in the mcrypt examples in your testbed file. It got me started on researching the entire concept of encryption and I wondered if I could use a private key / shared key scenario to store credit card numbers within Filemaker but keep them in an encrypted form and then decrypt them for export when I upload a batch file to the processor.
I'm mainly just trying to keep them out of harm's way, but also, I'm just the curious sort.
thanks for the help... and thanks for the amazing tool in "Smart Pill".
2-way encryption in using PHP?
I'm not sure I understand exactly but it seems like you have to have an unencrypted key somewhere. If you were to keep a private or shared key encrypted, I'm not sure how you'd use it without decrypting it first?
I would probably keep the key in a script and make sure that only full access users can access it. Another place to store it would be a custom function, again requiring full access to see it.
I may be missing something and I'm certainly not an encryption expert...
