When encrypted in QR codes, 4 additionnal bytes are added. Two null bytes and a CRC-16. It's the exact same CRC-16 as for the Wii blocks on the 0x5e first bytes. It seems that the CRC is ignored, the Mii Maker expecting the result of APT:Unwrap to detect integrity loss.

==CFHE object==
A 0xE-byte long linked list node. The format is 4-byte Mii ID (See Mii format) + 6-byte MAC + 2-byte previous node index (prev) + 2-byte next node index (next).
An invalid node has value: ID = 0, MAC = 0, prev = 0x7FFF, next = 0x7FFF.
The highest bit of these fields has some special meaning and isn't part of the index value.
==Checksum==
The algorithm used to verify the integrity of the database is based on [http://srecord.sourceforge.net/crc16-ccitt.html CRC16-CCITT], though it's an incorrect implementation. It is the same algorithm used to verify [http://wiibrew.org/wiki/Mii_Data#Block_format Mii Data on the Wii].
To obtain the correct value for the checksum, apply the algorithm to the first 0xC81E bytes of the database. This can be done using [https://gbatemp.net/threads/tutorial-give-your-mii-gold-pants-and-use-it-for-streetpass.379146/page-24#post-6569186 FixCRC]; alternativly a pseudocode implementation of the checksum algorithm is given below:
<source lang="python">
def crc16_CCITTWii(u8[]: data) -> u16:
"""Calculate a checksum of data using the CRC16-CCITT implementation of the Wii
This implementation uses 0x0000 as the starting value, which is different
from what CRC16-CCITT specifies.
"""
# note: a correct implementation of CRC16-CCITT
# would initialize this to 0xffff
u32 crc := 0x0
for byte in data:
# Iterate over every of the 8 bits in byte.
# Begin with the most significant bit. (7, 6, ... , 1, 0)
for bit in 7..0:
# & - binary `and'; <</>> - bitshift left/right; ^ - binary `xor'
crc := (
(crc << 1) | ((byte >> bit) & 0x1)
^ (0x1021 if crc & 0x8000 else 0)
)
for _ in 0..15:
crc := (crc << 1) ^ (0x1021 if crc & 0x8000 else 0)
# only return the lowest 16 bit of crc
return (u16) (crc & 0xffff)
checksum := crc16_CCITTWii(miidb[0:0xc81e]) # checksum over the first 0xc81e bytes
