    psp PRXdecrypter 2.0

    News/release from JasonUK:

    Here's version 2.0
    Check the readme.txt for full instructions if you havent used this before.


    Quote:
    1.9 --> 2.0
    - Working KL4E decompression in 3.80/3.90
    - Press LEFT on the D-Pad to signcheck all ~PSP encrypted files in the ms0:/enc folder
    - Totally reorganized the source code. Everything is now in one build. Internally the code is slightly different for 1.50, 2.71~3.71, and 3.80+.
    ` All functions are now loaded from prxdecrypter_0xg.prx (1 = 1.50, 2 = 2.71~3.71, 3 = 3.80+)
    ` At the moment, RLZ decompression is available in 1.50 if you put a decrypted 2.71+ sysmem_rlz.prx into ms0:/enc
    ` RLZ decompression is natively available in 2.71~3.71 but NOT KL4E decompression
    ` KL4E decompression is natively available in 3.80+ but NOT RLZ decompression (as they removed it)
    ` So, depending on what you want to decompress or decrypt, you may need to run it from a different firmware
    ` KL3E decompression is NOT yet available, so you can't properly extract the 3.80+ reboot.bin
    - Made the options a little more organized with a few dividers, and changed keys to make more sense
    - Press SELECT to switch between the normal output folder (which overwrites your input files) and "ms0:/dec" so the input files are kept separate from the output.

    Stuff I'll add next version:
    Menu system
    RLZ decompression in 3.80+ (by loading 3.71 sysmem.prx) - hopefully

    1.8 --> 1.9 (Bugfix release)
    - Fixed bug where pressing X for too long caused it to try and decrypt multiple times resulting in a huge log of error messages
    - Rewritten method of loading files for RLZ decompression in preparation for 2.0 which will have KLE decompression
    - Improvements to the logfile
    - Tweak to enable 1SEG.PBP decryption
    - More keys added (certain apps which run in pspbtcnf_app mode)
    - Fixes to prevent crash on 3.80
    ` NOTE: 3.80 has removed the RLZ decompression routines and replaced them with KLE. At the moment I have no information about the KL3E/KL4E NIDs and have therefore left them out of this version
    ` RLZ still works fine in 3.71 and below, and in 1.50 where you can load sysmem_rlz.prx to enable it as usual

    Default

    can you encrypt 3.90 prx's with this?
