Creating a self-signed SSL certificate, and then verifying it on another Linux machine
# Procedure is for Ubuntu 14.04 LTS.
# Using these guides:

# Generate the root (GIVE IT A PASSWORD IF YOU'RE NOT AUTOMATING SIGNING!):
openssl genrsa -aes256 -out ca.key 2048
openssl req -new -x509 -days 7300 -key ca.key -sha256 -extensions v3_ca -out ca.crt
