Windows 10 LTSC as an Arch Linux ARM RPi 3 Build Slave

Your SBC (in my case a Raspberry Pi 3) is likely not the fastest machine in your collection. Thankfully, if you have a laptop or desktop you normally use, you can recruit it to assist your Raspberry Pi in compiling Arch Linux packages for itself. It is fairly easy to do with another Arch Linux machine, but a little tougher if you don't have one running that.

I have two laptops, a ThinkPad X250 running Windows 10 Enterprise LTSC and an Apple MacBook. The X250's i7-5600U has a substantial amount more power than my MacBook, but runs Windows. This is not a big deal with the Windows Subsystem for Linux and distcc, a distributed C compiler infrastructure.

For this to work, both computers must be on the same network and they must be able to talk to each other.

maskify.py

Creates password categorization masks from big password lists
in a multithreaded fashion. Note that it assumes you have enough
RAM to hold the unique mask dict in memory. Used to analyze a 300M+
unique password list for types and occurrences. 

On an ODROID-C2, runs at about 50-52K passwords/sec.

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
