The DSiWare exported from a 3DS is located at "[[SD_Filesystem|sdmc]]:/Nintendo 3DS/<ID0>/<ID1>/Nintendo DSiWare". Filenames are same format as DSi: "<TitleID-Low>.bin". The keys/format for these files are completely different from [http://dsibrew.org/wiki/Tad DSi]. Like DSi, 3DS DSiWare exports seem to use [http://dsibrew.org/wiki/ES_block_encryption ES] block encryption. The below sizes include the 0x20-byte ES block metadata.

DSiWare exported from 3DS are encrypted using the same [[Nand/private/movable.sed|keyslot]] used for encrypting other 3DS [[SD_Filesystem|SD]] card data.
DSiWare exported from 3DS use [[Nand/private/movable.sed|keyslots]] initialized by movable.sed, these exports are encrypted with AES-CTR.
