Disclaimer: Please follow this guide being aware of the fact that I'm not an expert regarding the things outlined below, however I made my best attempt. A few people in IRC confirmed it worked for them and the results looked acceptable.

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!

The MIT License, Line by Line 171 words every programmer should understand The MIT License is the most popular open-source software license. Here’s one read of it, line by line. Read the License If you’re involved in open-source software and haven’t taken the time to read the license from top to bottom—it’s only 171 words—you need to do so now. Especially if licenses aren’t your day-to-day. Make a mental note of anything that seems off or unclear, and keep trucking. I’ll repeat every word again, in chunks and in order, with context and commentary. But it’s important to have the whole in mind.

	For symmetic encryption, you can use the following:

	To encrypt:
	openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

	To decrypt:
	openssl aes-256-cbc -salt -a -d -in encrypted.txt -out plaintext.txt


	For Asymmetric encryption you must first generate your private key and extract the public key.
