−| 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.
