How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

requirements_file = 'base.pip'

requirements = open(requirements_file, 'r')
content = requirements.read().splitlines()
content = list(set(content))
content.sort(key=lambda y: y.lower())
content = '\n'.join(content)

file = open('sorted_'+requirements_file, 'w')
file.write(content)

Small script which is able to look for and install packages targeting another
platform, using pip.

This simplifies the creation of distribution files for different platform.

Only works for Python 3.4 downloads.

# Fix user and directory permissions:
find . -type f -print0 | sudo xargs -0 chmod 664
find . -type d -print0 | sudo xargs -0 chmod 775

# Copy user permissions to group permissions:
chmod -R g=u .

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
