GPADX.PRF Files

These files (GPADX_MP.PRF, GPADX_CM.PRF, and GPADX_SP.PRF, "X" being the controller number) contain variables related to game settings.

Call of Duty 4: Modern Warfare, World at War

Call of Duty 4 stores the GPAD files in plaintext. The max size the file can be is 1000 bytes. It was then later patched by Infinity Ward because users started to edit the files to exploit the game.

World at War in the other hand, is encrypted using Sony's AES encryption algorithm. After decrypting that layer the GPAD's is going to be plaintext just like Call of Duty 4. Treyarch hasn't bothered in patching the files, which allows modifications on the game.

Both games use .cfg codes, which is easy to manipulate dvars (Developer Vars).

Black Ops

Treyarch has added additional protection on the save data. It is first encrypted using Sony's AES algorithm, after decrypting that layer it is additionally encrypted using the 3DES-CBC algorithm.

3DES key:

unsigned char black_ops_3des_key[24] = "Md8ea20lPcftYwsl496q63x9"

3DES IV (Initialization Vector)

unsigned char black_ops_3des_iv[24] = "0Peyx825J4S2ndpr54rW312z"

After decrypting this DES layer it is then plaintext and you are able to edit the file to your liking, allowing you to edit dvars and .cfg code.

Modern Warfare 2, Modern Warfare 3, Ghosts, Advanced Warfare

Ever since Modern Warfare 2, Infinity Ward started compiling the saves because of people taking advantage of cfg code in Call of Duty 4. They are hard-coded dvars that can only mod in-game settings like sensivity, in-game volume, and button configurations etc...
