'''Mii Maker''' lets you create Miis, like Wii Mii Channel. Here you can transfer Miis over [[NWM_Services|local-WLAN]] from other systems running Mii Maker(3DS/Wii U), or from Wii Mii Channel. 3DS Miis can't be transfered to Wii Mii Channel, only from Wii.
'''Mii Maker''' lets you create [[Mii]]s, and is the successor of the Wii's Mii Channel.
It can transfer Miis over [[NWM_Services|local wireless]] from other systems running Mii Maker (3DS/Wii U), or receive, but not send, from Mii Channel.

3DS Mii QR is a standard 57x57 pixel Level 10 High ECC QR code with 'Mii' logo in center (refer to [http://www.denso-wave.com/qrcode Denso-Wave Inc] web site for QR Code format specifications). It contains 0x70-bytes of binary data. 3DS seems to have a fully implemented QR-code decoder, as it can interpret such Mii binary data being encoded even in the smallest possible for that data size Level 6 Low ECC QR code. The data itself is encrypted with AES-CCM, xorpads can be determined from known plaintext here. The Mii Maker application uses the [[NS]] APT Wrap/Unwrap commands to encrypt/decrypt this Mii data. For the NS [[APT:Unwrap|Unwrap]] command, the Mii Maker application uses blocksize=12, noncesize=10, and inputbuffer-size=0x60.

For the NS [[APT:Unwrap|Unwrap]] command, the Mii Maker application uses nonceoffset=12, noncesize=10, and inputbuffer-size=0x60. Note that the actual nonce size is 8 bytes due to Wrap/Unwrap implementation, and the nonce data should be moved 12 bytes afterwards after decryption. The rest of the data at 0x8-0x5F is encrypted, and should be split into two parts after decryption, with the nonce data in the middle. (See [[APT:Wrap|Wrap]] and [[APT:Unwrap|Unwrap]] for more information)
