I will have to say that we have a piece of software that uses a wicked combination of the following:

-Sentinel 7.5 USB Key

*PLUS*

-CrypKey 6.1

It appears that the main exe for the program was obfuscated, and I rack my brain trying to kill the combination of these, while leaving the program in a working condition.

I am able to remove the Sentinel from earlier versions, but there's something funky with the Crypkey integration with it.

Other than those, I am from a much older generation of 'cracking', and what you kids do now just amazes and impresses me!
