| This had a minor refactor in [[6.0.0-11|6.0.0-X]] but is functionally identical.
| Mostly inherited from the Wii/DSi algorithm which used CRC-32 (0xEDB88320) with custom XOR-out (0xAAAA). 0x14C1 was added to produce the final result.
For the 3DS algorithm, only constants were changed: the polynomial was changed to 0xEDBA6320 and the addition constant became 0x1657.
The input to either function is an ASCII string of the format "%02u%02u%04u" where the parameters are month, day, and low 4 digits of the inquiry number. The low 5 decimal digits from the output u32 are then used for the master key.
Because of the date being used in the algorithm, this results in the master key only being valid on a particular day, though this is trivially defeated by setting the system time to the correct date that the key was generated on.
