Cryptopals is a set of cryptographic challenges, originally published here: https://cryptopals.com

Set 8 of the challenges was never published publicly, until late March 2018. However the cryptopals website was not updated to include the challenges. This gist compiles the 8th set of the Cryptopals challenges.

This guide offers the least time-consuming way of setting up Nginx for serving Git repositories over HTTP using Gitweb. The stuff here has been tested with Git 1.9.1 and Nginx 1.6.0 on Debian Wheezy. Probably also works for Ubuntu, etc.

Total time ~ 10 minutes.

Install

Enable wheezy-backports by adding this line to /etc/apt/sources.list:

deb http://http.debian.net/debian wheezy-backports main

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.
