Running Hashcat on Google Cloud's GPU-based VMs

In February 2017, Google announced the availability GPU-based VMs. I spun up a few of these instances, and ran some benchmarks. Along the way, I wrote down the steps taken to provision these VM instances, and install relevant drivers.

Update April 2019: Updated instructions to use instances with the Tesla T4 GPUs.

	# OBJECTIVE: Install Arch Linux with encrypted root and swap filesystems with an ENCRYPTED BOOT and boot from UEFI. We will
	also decrypt and mount our entire encrypted system using a single LUKS passphrase entry.

	# Note: This method supports both dedicated Arch installs and those who wish to install Arch on a multi-OS-UEFI booting system.

	# External USB HDD/SSD Installers Notes: Encrypted Arch installs can be booted and run from an external USB HDD or SSD, but
	# only when the installation is correctly set up. There are several necessary changes to my standard procedure you'll want
	# to make during the install process. Read my External USB HDD/SSD Installation section below before proceeding.

	Start GDB and execute the following commands:

	catch syscall ptrace
	commands 1
	set ($eax) = 0
	continue
	end

	Then, run the app and voilá! you can debug your program :)
