Before being decrypted, the encrypted header's CTR additionally encodes metadata used to validate package2's contents as follows:
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
* 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)
* Key generation = ((ctr_word1 ^ (ctr_word1 >> 16)) & 0xFF) ^ (ctr_word1 >> 24)
In [4.0.0], the metadata version field must be less or equal to 4.
In [4.0.0], the key generation must be less or equal to 4.
