For instance, if we run: ./john -fo=DES --test For me it would show something like, 2300K c/s My understanding is that my processor can perform 2300K DES Encryptions using descrypt of the candidate passwords in 1 second. However, I think this is not an accurate description. I would appreciate it if someone can elaborate over this (Solar Desginer especially :D ) Also, how is it related to the clock cycle and clock speed of a Processor? For instance, if I am comparing the benchmark for the same hashing algorithm using the same version, build of JtR on two different processor, how accurate is the comparison in terms in efficiency? I guess, cycles per byte need to be calculated for that but for this I need to understand the meaning of c/s in more detail. I love JtR and I would like to understand in much more depth at code level. Thank you.
