Hacking Nintendo Switch Parental Controls Bypass/Master Key Generation

[ReznorsRevenge]

Recently, I've been doing some research & thinking about possible vulnerabilities to the Nintendo Switch Parental Controls lock. Here's my situation:

• My switch is a Patched Mariko v2, and is updated past version 8.0.0
• Since I don't have full ownership over the Switch, I can't install a modchip on it.

Here are some questions that I have about master key generation:

• If I used Nintendo's official Master Key service and got a valid Master Key, could I make a reverse-engineered version of the mkey.salthax.org backend that takes the Inquiry number and the date of the Switch to find the Device ID, so that I could use the original mkey program?
• On the topic of Nintendo's official Master Key service, once you've filled in all the fields and requested a master key, how does Nintendo give the Master Key to you? Does it display it on the webpage? Does it email/text it to you? If it is displayed on the webpage, does the key get fetched from an API?
• What's the deal with PRODINFO? How would I extract the Device ID from it?
