==PS3 Protections==
There are 3 possible protections in "PS3 Game Saves" that can be used together at the same time, it depends of the game wich ones are used and what files are affected

===PS3 Game Save files encrypted===
Game developers have the option to encrypt the files generated by the game (when the game writes/reads the Game Save). This encryption/decryption is managed by the game and is different for each game, in some games this encryption doesn't exist, this allows modifications/cheats for Game Saves which files are not encrypted or the encryption method is known, and are not signed by PS3 (read next section below)

For more info about unencrypted game saves see: [[Game_Modding]]

===PS3 Game Save files signed===
PS3 can generate a signature for each file inside the folder, this signatures are stored in the [[PARAM.PFD#Protected_files_table | Protected files table ]] inside the file PARAM.PFD

This table inside PARAM.PFD is limited to a maximun of 114 signatures, seems to be a number high enough for all games developers to protect all, but the fact is usually only a few files (the important ones) are protected with this signatures, one of them uses to be PARAM.SFO

This signature generation/verification is managed by the PS3 and not the game, and can be used together in combination with the previous method (1ºencrypted + 2ºsigned)

===PS3 Game Saves Copy Protected===
There is a "feature" in "PS3 Game Save" format that allows developers to disable the "copy" function to an external USB storage device (by pressing triangle over their icon in XMB with the option "copy" of the side menu)

This "copy protection" is managed by a "flag" that can be turned on/off inside PARAM.SFO, see: [[PARAM.SFO#ATTRIBUTE_in_SaveData|Copy protection]]

But... this means you need to modify PARAM.SFO (the signature changes)... so this only works when PARAM.PFD doesn't contains the signature of PARAM.SFO (only a few old games)

Also, This can be used together in combination with the previous methods (1ºencrypted + 2ºsigned + 3ºcopy protected)
