omg.. you really are retarded. because jtagging was made for xbox its a chip that is installed on the main motherboard that allows you to bypass HARDWARE RESTRICTIONS. and decryption is for software. they are both similar but totally different things. Your not going to crack a 128 bit encrypted disk any time in the near future. you need to learn what encrytpion is and the different types.. Silent you sir need to go take a basic operations of computers class.
