I’ve been searching for a few days in different forums trying to find an example of DES that gives the key/output values for all 16 layers. I found one that gives the encryption which helped me fix that part, but my decryption isn’t working correctly. It’s easier to debug if I know what I’m aiming for.
Is there someplace that has all the encryption/decryption round outputs that I can look at?
Should they be the same only backward? Decryption round 1 output = encryption round 16 output?
Thank you for any help you can give.
