Changes

As of [[7.0.0-13]] the system now supports a new encryption method for the secure-cryptotype, the CTR for this is the same as before. This is enabled when NCCH flag[3] is non-zero. When enabled, the [[RomFS]] and [[ExeFS]] files which don't have filenames "icon" or "banner"(that is, ".code") are crypted with a different keyslot. This keyslot is [[Savegames|initialized]] by the 6.0 gamecard savegame keyY init function during boot, using a different portion of the [[Savegames|final]] hash(this keyslot is separate from the one used for the 6.0 save crypto).

With New3DS [[9.3.0-21]] new NCCH crypto support was added, enabled via ncchflag[3]=0x0A. This is almost identical to the v7.0 crypto except with a New3DS-only keyslot, however this also uses unknown encryption for RomFS.

With New3DS [[9.3.0-21|9.3.0-X]] new NCCH crypto support was added, enabled via ncchflag[3]=0x0A. This is identical to the v7.0 crypto except with a New3DS-only keyslot.
