Homebrew developer jas0nuk has released an updated build of PRXDecrypter. Primarily geared towards developers, the application allows users to decrypt PRX modules and other miscellaneous firmware resources.

Notable changes in 2.0 include the ability to signcheck all ~PSP encrypted files in the ms0:/enc folder by pressing LEFT on the D-pad, in addition to functional KL4E decompression in 3.80/3.90. For the complete changelog, look below.

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.
