== PS Vita Keys ==
These are the PS Vita Keys.

== Vita Game PKG Keys ==
These AES-CTR 128-bit keys are used in Game/App PKG file decryption. Vita keys use a different algorithm, you first encrypt the IV with the correct type of key, then use the result as the actual key for the CTR. Every pkg will use a different key as a result of this.
