Here's why:
PKG's are SIGNED with a Sony key. If you attempt to edit the file, it must be resigned. Say you do know the key. If you do, then why are you attempting to edit a PKG? You could just decrypt the HDD, then edit the file on the HDD. You could do much more than that, even, including making your own custom firmware which supports extracting game data to a USB Drive. Anyone who ACTUALLY thinks they have done anything with PKG's is wrong. Seriously. People with Debug/Test PS3's with all those extra debugging features can't even do anything with them. If you think that looking at these files in a hex editor is going to do anything, it won't.
Just a little something to prevent people from getting false hope.
I'm probably wrong about some of this, but I do KNOW that PKG's are signed and can't be edited in any way shape or form.

I would love to know why you don't use HxD for it. & I would love to know why you want to leech off me :} <-- Actually I don't care, because I won't tell or give proof. You'll just see me posting a challenge lobby SOON.

Here's some quotes from Xorloser's blog about how long it would take to actually get the correct key for this(PKG'S use a 256 Bit key I believe) by bruteforcing
Our universe is estimated to be around 15 billion years old.
If you actually had it anyways, why not release it and bring happiness to the PS3 world?

For those not fluent in “calculator speak” 1.7e+32 means 1.7 x 1032, which means you move the decimal point to the right 32 times. So then the number is 17 followed by 31 zeros. This seems like a lot of seconds, but it is hard to gauge time in large numbers of seconds. So for the benefit of the humans here, lets use years instead of seconds for our measurements of time.
First we need to work out how many seconds there are in a year. We will approximate to simplify the math:
365 days x 24 hours x 60 minutes x 60 seconds = 31,536,000 seconds in a year
Now we can work out how many keys the bruteforcer can test in a year:
2,000,000 keys/second x 31,536,000 seconds = 63,072,000,000,000 keys/year
Finally we can work out the maximum number of years it would take to find our key:
2128 keys ÷ 63,072,000,000,000 keys/year = 5,395,141,535,403,007,094,485,264 years
2128 keys ÷ 2,000,000 keys/second = 1.7e+32 seconds

Another way of writing these numbers is:
5,395,141,535,403,007,094 million years
5,395,141,535,403,007 billion years
5,395,141,535,403,007,094 million years
5,395,141,535,403,007 billion years

But what if you were to optimise your bruteforcer? And what about increases in computing power every year? What if you created a distributed bruteforcer program that everyone around the world can run? What if you were to randomly guess keys instead of trying all keys incrementally?
Assuming I could optimise my bruteforcer to be 1,000,000 times faster, and that computers suddenly became 1,000 times more powerful and that every single person in the world (7,000,000,000) owned one of these new computers then:
5,395,141,535,403,007,094,485,264 years ÷ (1,000,000 x 1,000 x 7,000,000,000)
= 770734 years

Kind of ridiculous.

THE EDITED PKG MUST BE THE SAME SIZE AS THE ORIGINAL IN THE END
You can use PS3 Proxy to put any PKG on your PS3 you want. You'll need PS3 Proxy(of course) and you'll need to set it up. This is not a tutorial on how to set PS3Proxy up, but here is a good one:
You must login or register to view this content.
After that, you'll need to begin the download of anything(I use the Rock Band song Still Alive, as it is free and small). It doesn't have to stop at 1%, but just don't let it finish. Go into Logs in PS3 Proxy and copy paste the one on the top into your browser. When you download the file, right click on it and choose properties. You should see: File Size(number of bytes here). Now, edit this file as MUCH AS YOU WANT/REPLACE IT WITH ANOTHER SIGNED PKG/ANYTHING. Now, save the file and choose properties again. Subtract the amount of bytes it is now to the amount of bytes it was and then go into a Hex Editor and then Insert the byte difference(in my case it was 3935 so I added 3935 bytes IN DECIMAL to it). Now, go to replace files and click add. In the first box, put the link to the PKG you used and in the 2nd box, put the shortcut to the edited PKG(such as C:\PKG.PKG) and then redownload the file from the store. CHOOSE DOWNLOAD IN BACKGROUND. Wait until it gets done and now you have an edited PKG on your PS3! It won't install, however, until we can disable/paralyze the hypervisor and if it is a proper PKG it will install. In the end, this is practically worthless EVEN if you find 2 EXACT same file sized PKGs, as the headers vary and changing them will break it.
Enjoy!

That was just how to get it on PS3. It doesn't install at all(returns an error) because it is not signed.
It wasn't even properly edited in that case, I just changed a byte.

What if you were able to edit the pkg file while the ps3 had it decrypted and was reading it. On Xbox 1's, to softmod it, you had to edit the hard drive. The hard drive was locked by a special key that was specific to that Xbox and it only unlocked the hdd when it was reading it. To mod it then, you had to edit the hdd while the xbox was accessing it and unlocking it with it's specific key. Maybe I'm just a retard though.
