These tools allow you to decrypt and re-encrypt the Edat, among other useful functions!
Snowydew has just released an Edat Encryption/Decryption tool.
As its name says, the tool allows decryption and re encryption of Edat. Also, you can extract a iso.bin.edat, and can decrypt eboot.pbp's / eboot.bins for further game modifiying.
Download it HERE!Decryption of act.dat and rif keys, the re encryption part however isn't 100% since we are missing a variable or two, but we can resign them as free npdrm without sony tools.
A large portion of npdrm right here. It "CAN" do it, it's not implemented just yet. It requires testing though.
The encrypton process is a PoC until bytes 0xb0 - 0x100 are figured out
There is some goodies in the files, check it out if interested in psp,ps1, etc on your ps3.
