Encrypted files on flash appear to have some sort of header

Here are samples of metldr header from 2 different consoles

== Observations / Notes ==
As you can see, some parts appear static depending on their purpose:
metldr
00000840  00 00 0E 8E 99 87 3B C7 15 F2 80 80 9C 30 22 25  ...Ž™‡;Ç.ò€€œ0"%

00FC0010  00 00 2F 4B xx xx xx xx xx xx xx xx xx xx xx xx  ../K............
per console in both samples

The first 4 bytes appear to reffer to length. eg:
metldr length: 0xE920
0x00000E8E * 0x10 = 0xE8E0 + 0x40 = 0xE920
bootldr length:  0x2F4F0
0x00002F4B * 0x10 = 0x2F4B0 + 0x40 = 0x2F4F0
Header shown is 0x20 bytes, perhaps this means there is a 0x40 byte header. I was not able to find any correlation of the other 2x12 bytes here, perhaps these are keys of some sort.
also to note that these values are found within the eeid region.
