Heden, of DeLiGhT have released a easier way to decrypt SELF/SPRX without the use of a payload, to quote:

Heden, of DeLiGhT, has informed us of his, easier to use, SELF/SPRX Decrypter application. Unlike graf_chokolo's method, DeLiGhT's application does not require a special payload to decrypt.

SELF/SPRX DECRYPTER - V0.5 BETA
----------------------------------------------------------------------------

    SELF/SPRX DECRYPTER

    12/04/10 - V0.5B - Initial BETA Release
        - Decrypting internal PS3's SELF/SPRX files
        [BETA - The decrypter hangs on some files]

    GameOS utilizes files to make the console work (I won't give details)
    These files (SELF = EXE, SPRX = DLL) are stored in /dev_flash
    This tool enables to decrypt these SELF/SPRX files
    Such a decrypter will only help people who know what they do ;-)
    The application is stable enough even if it hangs on some files

    Howto :
        First, install the .PKG provided in the archive

        - Put the file you want to decrypt into :
            /dev_hdd0/game/DCRY00001/USRDIR/SOURCE/
        - Launch the decrypter
        - Get the decrypted files from :
            /dev_hdd0/game/DCRY00001/USRDIR/DESTINATION/

    The current version decrypts only one file per launch
    Make sure to have only one SELF/SPRX file in /SOURCE/ directory

    This decrypter does not use the grafchokolo's payload nor HV syscalls

Thanks for posting , front paging now.

Edit:
Front Paged.

When i tried this to begin with, it didn't work, but thanks to a tip by Heden in the comments reply on PSGroove.com, i was able to decrypt .sprx files

Originally Posted by Heden I made a lot of tests with files coming from /dev_flash/sys/external. The results were good except maybe 1 or 2 files (tested 6 or 7 files). The HB seems very unstable when I'm using files coming from /internal or /vsh/module...

no problem , gonna give it a look next week. hopefully its been made with psl1ght and we can play about with .self's from usb soon, i think this is a major step to a better understanding on how the magic happens for all us common folk.
