By default encrypted regions are compressed with an LZ77 variant, then encrypted. The spec allows for both unencrypted and uncompressed regions to exist. Retail SD card CXIs must have the [[ExeFS|ExeFS:/.code]] compressed. Development units use a fixed system key for system titles. On retail part of the input [[AES]] engine key is unique per NCCH, the AES engine internally generates the final-normal key.

Retail CFAs use NCCH product code "CTR-P-CTAP", while retail title/gamecard CXIs use NCCH product code "CTR-P-XXXX". This product code is the NCCH [[Serials|serial code]]. The region-locking info checked by home menu is stored in the [[SMDH#Flags|icon]].

All of the hashes stored in this NCCH header are over the cleartext data. The ExeFS/RomFS superblock starts at offset 0x0 in the ExeFS/RomFS, and the size is specified by the hash region fields.
