Reminder to self write a JavaScript NoDrives encoder/decoder on a web-page

A long time ago, I wrote about How to hide an entire drive from prying eyes on Windows 10 | Windows Central.
The easiest way is still to add/modify a NoDrives value in the Registry, but regrettably [WayBack] NT Drive Calculator – The ‘NoDrives’ Registry Key Value Calculator is down (it was a server-side solution, so the WayBack Machine link does display a page, but the calculator does not function).
My use case is that I have an existing NoDrives value that I want to update (as there have been one or more drive letters added/changed).
Via [Wayback/Archive] windows NoDrives calculator – Google Search I found [Wayback/Archive] Quick Tip: Is a Drive Hidden From Windows Explorer (Using NoDrives Registry Entry) | Žarko Gajić pointing to [Wayback/Archive] NoDrives – Windows CMD – SS64.com which has sort of a calculator but:
- it does not update from the drive-letter checkboxes if you accidentally modified the numeric
NoDrivesvalue - modifying the
NoDrivesvalue does not update the drive-letter checkboxes - only supports decimal
NoDrivesvalues (hexadecimal would be convenient since it is a bitmap)
For my reference:

NoDrivesvalue bitmap from my original post:
