"XCONFIG_XNET_MACHINE_ACCOUNT_CATEGORY"
encrypted data at entry 0 and 1 using HMAC-SHA, data matches except entry 0 has version field in front of data (00000001)
digest used for HMAC-SHA is at 0x0 (0x4 for entry 0), confounder is at 0x14 (0x18 entry 0) data encrypted using XeKey 0x17
!!!BE CAREFUL WHILE WRITING IT!!!
entry 0 and entry 1 must match, so be sure to write the data to entry 1 and then 0x00000001 + data to entry 0
if they don't match, xbox will blank out both entries
doesn't actually seem to be used in live auth at all
FUN FACT: XeKey 0x17 is (possibly?) stored in KV, so if you swapped keyvaults at all it won't decrypt properly

"XCONFIG_XNET_PARAMETERS_CATEGORY"
looks the same as MACHINE_ACCOUNT, but encrypted with different key/method?
