| Used by Boot9 for generating the console-unique AES [[AES_Registers|keyXs]]. However, due to a bug(?) in Boot9, only the first 0x1C-bytes here actually affect console-unique key generation. The rest of the data is used for hashing, but that output hash only gets overwritten without being used afterwards. | | Used by Boot9 for generating the console-unique AES [[AES_Registers|keyXs]].

Note that the size passed to the Boot9 keyinit code for console-unique-buffer-size is 0x70, hence this includes the below OTP hash. | |||
