PS4 PUP Decrypt and Unpack

I don't actually own a PS4 at this time although my son does so im not missing out completely, heres some news for those into hacking the PS4:

idc has officially released the C source code for tools to decrypt and unpack PUP files on PS4. These are native tools which uses the PS4 kernel to decrypt the contents of an update file. Thanks goes to GaryOPA for the heads up, you can read his story over at maxconsole.com.

Nice, perhaps it might make custom firmware or some other hack possible for the PS4. Mine is still on v4.01 since that announcement of a possible exploit for said firmware (and as a result unable to log into PSN because of that).
