That's not spamming. I did that to emphasize that it was very long. It's almost impossible to have the kind of time to crack that encryption.

Does anyone know if RSA is even used at all? FYI, 128-bit RSA is way too short. Perhaps you were thinking of AES which is almost certainly used.

PSP uses 128 AES, not RSA. So it would take billions of years for one super computer to crack it.

It's pointless to crack the key; first off al it's almost impossible and if you done it sony will add some new keys in the next firmware....
