Rainbow Tables are maybe dead for the general case, but in my case they are perfect.
I'm trying to "steal" DES-keys from many many units which only use single DES for generating the authentication value. I've hacked the unit so I can choose plaintext and I receive the output/authentication value back. If I then have a precalculated Rainbow Table for a fixed input, I will be able to find the DES-key in very very short time. I don't want to wait 10 days for a brute-force attack to do the job for me, then Rainbow Tables will be perfect.
So I really want to find a way to use Hashcat to encrypt a single plaintext with many many DES-keys. Can someone please show me how this can be done?
