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. | By default encrypted regions are compressed with an LZ77 variant, then encrypted.
