* Everything stored under sdmc/Nintendo 3DS/<ID0>/<ID1> and [[Flash Filesystem|nand/data/<ID0>]] is encrypted with console-unique [[AES|keyslots]], everything in the CTR-NAND FS encrypted using console-unique keyslots is likely stored under that directory as well. All CTR files under these directories seem to use the keyslots initialized by [[nand/private/movable.sed]].

* ID0 is the first 0x10-bytes from a SHA256 [[nand/private/movable.sed|hash]].

* ID1 is the scrambled SD card CID from the SD card which this directory was originally created on. To generate this directory name from the original CID, first the CID is rotated 8-bits to the left. Then, each u16 is moved as described in the below table:
