这个能干什么？
解密并解压PS3 PSP 以及游戏的PKG文件（不包括升级包的那种PKG）
怎样使用？
打开你想解压的pkg文件或者拖放到'extract package'上
现在只有windows版本
这个可以用来签名游戏的PKG吗？
现在不行，这个写来主要是为了解压。源代码包括在内了，稍微改改进行方向操作就可以进行签名

The algorithm was a bit of a pain to reverse but the keys could be easily grabbed with a lv2 exploit. So here we are, this app was done but the problem is it couldn't be leaked because I and a few other people who were entrusted with it, were kinda afraid that sony would change the keys and fix whatever exploits we had (turned out they didn't) but since we can now get whatever new keys they add/change this has become a quite irrelevant concern. The next concern was piracy.
There was nothing at the time justifying a release for that application, most people would just not have a legit use for it so releasing was out of the question.
So what changed our minds? Well, the 27C3 CCC Epic Fail happened, and Segher (props to him!) figured how to conveniently calculate private keys and suddenly a legit use appeared, as people would/might need to encrypt their packages to install their own signed apps onto their consoles.
Since people suddenly became interested in the game packages format, we just thought releasing that app would spare them the (hours of) work of reversing the encryption algorithm and that this code would not go to waste.
Special thanks to someone who helped a lot but whishes to remain anonymous.
Greetings to Segher whom, I believe people tend to forget too often.
