To quote: An anonymous developer has released a K_License Extractor for use on retail and debug PKGs.
The k_license is a unique license string generated and embedded in PSN and other PKG files. The script will retrieve and display this k_license when ran.
Please note the app is in the form of a python script and meant for experienced devs.
this is for extracting the "k_license" string from a pkg file in no way will this help you in obtaining a dlc package that will run on your ps3 (it can read but not write the string into the file as it appears from the description)... if you want pkg files I suggest you look here:
Hopefully scene groups will now release DLC's to, that would be awesome.
Hopefully this will lead to those of us who have multiple machines being able to sign content that we have bought for all of our machines, instead of it being locked to one machine.
