@mick0,

I thought I'd design my own VUK finder program with GUI, which I have mostly done using a list of processing keys, however, this method only works up to MKBv62.

I would like to better understand the Device Key to Processing Key method as I want to test possible device keys from PS3 firmware to see if they can calculate the correct processing key for a given MKB (v63 - v66). I had thought about using libaacs but I don't really understand some of the code (especially the part regarding device keys, uv's, v_masks etc) or how to use it. (I am a c# programmer and would like to understand the method so I can then either convert some c++ code to c# or write my own)
