When this exists in the beacon, this is the tag1 used with [[NWMUDS:DecryptBeaconData]]. The data stored here is the 0xFA-bytes following the previous encrypted data in tag0, for more space for storing the encrypted data.

The above structure is for the plaintext version of the encrypted data.
This data is encrypted with AES-CTR, by NWM module in software. The AES key is stored in NWM module itself. See above for the CTR. The size of this encrypted data is 0x12 + (0x1E*val), where val is the u8 from networkstruct offset 0x1D(zero when the u8 at networkstruct offset 0x8 is value zero).
