- Despite retiring
from the iPhone and PS3 scene shortly before PS JailBreak
first surfaced (amid rumors
from one reseller
that appear to point in his direction), today GeoHot
has reappeared and shared dePKG which is a PlayStation 3 Firmware Package Decrypter!

In his post
simply stated the following, to quote:
"A Little Gift for the Scene
#1419148 - Pastie
Decrypt pkg files computer side.
Mad props to fail0verflow
states the following there: "CORE_OS_PACKAGE is NOT a .tar, it's a flash image - to extract it's contents you need to parse it out... a really shoddy/quickly made win32 built extractor for CORE_OS_PACKAGE is attached. Drag and drop your decrypted CORE_OS_PACKAGE onto the exe and it will extract the binaries inside (keep in mind most everything inside it is crypted, it contains the lv1/lv2 selfs and some spu modules and the like.) There shouldn't be anything in there that would prevent a very fast port to *nix (and many thanks go to graf_chokolo for partially documenting the structure on his hv reversing page at lan.st wiki.)
Also did a msys build of the depkg for windows which doesn't rely on external code, source included along with all the COPY notices that go with the aes implementation I used (also I'm running it on win7 x64 from the command line without issue, though it is a 32bit targeted build.)"
As a follow-up, Mathieulh
Tweeted the following confirmation: "http://pastie.org/1419148 <== thx geohot /me whistles"
To quote from PSGroove: "The app is very useful for devs, that are planning to look into Sony's official firmware files. dePKG is a linux app, that will decrypt PKG files (not to be confused with PSN PKG files), that are within PS3UPDAT.PUP files.
This will allow devs to take a look at files such as CORE_OS_PACKAGE.pkg, from the convenience of their PC. Previously, the only way to take a look at these files, was via graf_chokolo's method, which utilized the PS3. Geohot's app is ready to be compiled and includes the necessary decryption keys."
