I don't think anyone who has replied thus far has actually read what the author wrote. He said this does NOT use a bf method. If I understand it correctly, he's using all possible combinations of 32-bytes that can be found in the source file. The time required to calculate that isn't much at all. Of course, this would require the lv0 key to just be sitting there unencrypted, so pretty unlikely, but I guess one can dream. Maybe a good enhancement (for the sake of completeness) would be to first try decrypting using all known keys and then searching for lv0 key.
Either way though, I can't think of any reason lv0 key would be in any file but I guess you never know. Nobody would have expected Sony to use the same "random" key in their signing algorithm either, but as it turned out they did and all someone had to do was look.
I believe the real hacking has to be done on the hardware, like the good old days of mod chips. Nothing can equal a good mod chip, look at the 360, can run isos from external HD the 360key.
Need someone with some good tech skills and knowledge on the PS3 architecture to release some mod chip, and voila. Why being stubborn about finding keys and making some CFW ?
A bit of soldering and some tools and you might find what you're looking for. I believe the next level of PS3 hacking resides in mod chip, like the 360.
The xbox 360 security is a lot less complicated than the ps3. The days of say PS1 where it was so simple as to inject "SCEASCEESCEJ" over and over between the drive and the cpu (one each of the magic letters for each region that the drive read from the subchannel data on original cds), or the ps2 days where it was more complicated but once it was done there was no such thing as firmware upgrades are gone... this is where it is now for ps3...
technically the x360 doesn't use a modchip its just a replica pcb, but a blank 1
So... He gets a, let's say, 3.7+ EBOOT and tries to decrypt it with every possible key combination possible? I suggested that for PS360 Team a few months ago, but nobody gave attention.
