| Decrypted header's CTR. Also used to calculate the size of the entire package2 with the raw header: size = word2 ^ word3 ^ word0.
| Header's CTR, official code copies the pre-decryption CTR over the decrypted result. Also used as metadata.

Each section follows each other immediately and is encrypted with the same key used for encrypting the header.
Each section follows each other immediately and is encrypted with the same key used for encrypting the header.
The section offsets are relative to a base, which is typically 0x80000000 pointing to the base of DRAM.
The section offsets are relative to a base, which is typically 0x80000000 pointing to the base of DRAM.
Before being decrypted, the encrypted header's CTR additionally encodes metadata used to validate package2's contents as follows:
* Size of the entire package2 with the raw header = ctr_word2 ^ ctr_word3 ^ ctr_word0
* Metadata version field = ((ctr_word1 ^ (ctr_word1 >> 16)) & 0xFF) ^ (ctr_word1 >> 24)
In [4.0.0], the metadata version field must be less or equal to 4.
