	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.
