    Thumbs Up PS3 PKG building/signing - joint effort

    With recent MFW from Kakarotoks it seems that building and sighning valid PKGs is a good thing to do :^)

    It's obvious that many devs are already working on this subject, but I think also it wouldn't hurt if we continue to share our thoughts on pkg format and may be some how speed things up

    here are some PKG header offsets....

    take a look to ungpkg from ps3tools. you will need gpkg-key in $HOME/.ps3

    sure. key needed for decryption. But in order to _build_ pkg you need to ecrypt and sign it properly. Currently it is not known (at least no public info) how to sign...

    Not true NGU user AlphaDenver has confirmed to have a working signed FTP server. He had a video released but took it down due to it being publicly released.

    Yes, signing is possible.

    So how to you go about signing the .pkg(s) then?

    I tried makepkg from fail0verflows ps3tools, but I don't know what to put in the [key suffix] [version]. Does the tool even sign

    geofferey@ubuntu:~/PS3TOOLS$ ./makepkg
    usage: makepkg [key suffix] [version] filename.pkg dir_with_files
    perror: Success

    Spent some time looking around and there should be some signing tools soon. I would guess within the next two weeks.

    Geohot has a pup and a sample on his site which he just updated sometime yesterday. Obviously he has the ability to sign pkg(s) so it's only a short wait now.

    makepkg retail 341 test.pkg dir_with_files

    Thanks mate I'm going to try it on some source now and see if it will run. Do you know if it's signing them?

    Also where may I go about finding the edit button on this forum?

    Users can only edit posts for a few minutes each to fix grammar/spelling errors etc, after that the button disappears basically.

    Is it possible to extract game packages that have the .sdat extension?

    In a hex editor they start with NPD.
