doesn't decrypt proto prxs properly (0.6.5 arc)

[zecoxao]

for some reason the tool doesn't decrypt prxs from proto 0.6.5 archive but the old tool i used to use (decrypt_prx) does

my friend Zer0Tolerance has found out why. the last step with kirk 0xB (SHA1) fails, pspdecrypt uses this, my prx decrypter does not.
