Utility to block unwanted keys

A small/lightweight executable or DLL to only allow user to use ordinary keys on any keyboards.

The software while running should only allow user to press the following keys:

- Alpha numerics: A-Z, a-z, 0-9, spacebar

- Symbols: ` ~ ! @ # $ % ^ & * ( ) - _ + = { } [ ] | \ : ; ' " < > , . ? /

- Arrow keys: up, down, left, right

- Control/function keys: Shift, F5, Esc, Tab, CapsLock, Home, End, Delete, Backspace, Page Up, Page Down, Enter

Any other keys not listed above must not take any effect whatsoever.

The software must work on basic and professional versions of Windows 7, 8 and 10.

Compilable source code must be provided upon completion.

Please note that no UI is required.

- The software must be portable (no installation required).
- If it is an executable, only a single file is required for it to run. If it is a DLL, there must be only one DLL required.
- The executable or DLL only takes effect after being executed within a Windows session.
- The executable or DLL must restore the system back to normal upon exit.
- The executable or DLL must have a secure way to terminate. Only the person invokes it can terminate it by using a passphrase via command line parameter or function call parameter (if DLL). The software must not exit unless being terminated with correct passphrase; or system shutdown.

- The executable (if not DLL) must run in the background.
- While running, it must perform the system-wide blocking.
- The executable or DLL must work on both Windows 64bit and 32bit.

Guys, I need to elaborate due to the overwhelming number of bids. Any key not listed above must not take effect whatsoever (either pressed by itself or in a combination). For instance, Ctrl+Alt+Delete must not work as Alt is not allowed, Win+L must not work as Windows key is not allowed. If you can do that, please message me as I am very keen to go ahead. Feel free to update your bid amount if you see fit. Please contact me only if you can do it.
