So, I've got an app at work that encrypts a string using ColdFusion. ColdFusion's bulit-in encryption helpers make it pretty simple:
encrypt('string_to_encrypt','key','AES','HEX')
What I'm trying to do is use Ruby to create the same encrypted string as this ColdFusion script is creating. Unfortunately…

I generate our product keys based on
a client name (which could be a variable length string)
a 6 digit serial number.
It would be good if the product key would be of a manageable length…

Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike?
Or do all…
