this is just an small portion what the app does.
Once the 3K3Y Ripper app has loaded the PS3 BD drive keys it will attempt to
authenticate the drive. When the authentication has succeeded you may begin to use it to
rip PS3 games.
Decrypting/Encrypting PS3 ISOs
You may wish to compress (zip) your game rips for archiving. PS3 games are, however,
encrypted and do not compress well. Before attempting to compress a PS3 game you
should decrypt it using the 'ISO Crypto' function of the 3K3y Ripp3r.
To decrypt a PS3 ISO:
• Click the 'ISO Crypto' button and select the ISO file you want to decrypt.
• The game ISO will be decrypted to a file with the same name but the extension
• Once decrypted the file can be compressed.
So this app verifies your bd keys, and encrypt/decrypt the games.
Also rip games, and crypt them etc.
