mkey is a master key generator for the Parental Controls functionality on various consoles from a certain vendor. Currently, this includes the Wii, DSi, 3DS, Wii U and Switch.
This allows resetting Parental Controls (due to being locked out) without having to contact customer support.
Tool to generate the 'master key' (unlock code) for 3DS, Wii U and Switch parental controls, in case you forgot the PIN. 3DS / Wii U / Switch master key generator.

V1 and Wii U support was added in January 2016. V0 support was added in April 2016. V3/Switch support was added in. Forgot Parental Controls PIN The information in this article can help you when the parental controls PIN on a Nintendo Switch needs to be located or reset. Note Parental controls can be set on the Nintendo Switch system. How to Change the Parental Control PIN Important: Once the Nintendo Switch console has been linked to the Nintendo Switch Parental Controls app on a smart device, the PIN. 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.

Python and C implementations are available in this repository. These function very similarly.
As of writing, system support is good - all algorithms in use are supported, provided one can extract the necessary keys from the system firmware.
For some algorithm versions (especially 3DS v2) many keys are required from the system firmware in order to generate master keys. These can differ between regions and system versions. The best documentation for these is in the code, which covers the situation on all supported devices.
Some 3DS-specific documentation on the algorithms seen so far can be found at: https://3dbrew.org/wiki/System_Settings#Parental_Controls_Reset
