The simplest one would be using npdtool

For example key.edat

npdtool dr key.edat output.edat <rap key>.rap

I built it for anyone who needs it: https://mega.co.nz/#!Bg9DwAqZ!uqWBaSjXHF...w8Z1xzuPyw

(Hint: On Windows 7, shift+right click in the folder where the .exe is, and open a terminal/command window. Then type make_npdata.exe (type just that) and you will see the program usage, without a terminal window that exits when the program is done, so you don't see anything...)

Or look at this I guess

i just tried it to decrypt a EDAT file from Jetpack Joyride , seems to be not working . Probably flag 0x3C and 0x3D are unsupported yet.

You have to specify klick also.

make_npdata -d input output klick rap

Thanks it is okay now . The source code of make_npdata seems to be supported 0x3C flag though not yet on RPCS3 .

Just reminder for anyone if you are going to use npdtool , make sure you are using npdtool fix 2 , otherwise the EDAT decrypted will not be able to use with RPCS3

The best would be using make_npdata that should work straightly.

To decrypt EDAT file you need .rap file.
You can get ".rar" file by use "psnstuff" program
Then you should to put files ".edat , "npdtool.exe" and ".rap" into same folder for example I had put it into C:\edate
After it you should to run command promt there need to execute a command "C:\edate\npdtool.exe dr C:\edate\key.edat C:\edate\output.edat C:\edate\<here name of rap file>.rap"
