AuthEncryptionType1: The key is derived essentially the same as the data-frame CCMP key, except the input data for hashing is the 0x10-bytes at +0x38 (this also only supports using [[SPL_services|Generation]] 0x13, returning immediately if the input param indicates otherwise due to the [[#Protocol|Protocol]]). | AuthEncryptionType1: The key is derived essentially the same as the data-frame CCMP key, except the input data for hashing is the 0x10-bytes at +0x38 (this also only supports using [[SPL_services|Generation]] 0x13, returning immediately if the input param indicates otherwise due to the [[#Protocol|Protocol]]).
