# Mina Deploy
# ===========
#
# Adapted from Creative deploy stack in Manabalss v4, Mar.2015, updated to support staging on Jun.2015
# On first deploy do: mina setup --verbose
# Then do           : mina deploy[initialize] --trace
#
# Usage examples:
# mina deploy[soft,seed,compile] to=staging # deploy task with all options | a simple `mina deploy` will deploy to production
# mina rake[db:seed] # for multi-argument tasks # mina 'rake[payments:refund[arg1\,arg2]]'

# Kudos to https://datacenteroverlords.com/2012/03/01/creating-your-own-ssl-certificate-authority/

# Create the Root Key

# The first step is to create the private root key which only takes one step.
# In the example below, I’m creating a 2048 bit key:
openssl genrsa -out rootCA-key.pem 2048
# The next step is to self-sign this certificate.
openssl req -x509 -new -nodes -key rootCA-key.pem -sha256 -days 1024 -out rootCA-cert.pem

#Overview
#    The following is an extremely simplified view of how SSL is implemented and what part the certificate plays in the entire process.
#    Normal web traffic is sent unencrypted over the Internet. That is, anyone with access to the right tools can snoop all of that traffic. Obviously, this can lead to problems, especially where security and privacy is necessary, such as in credit card data and bank transactions. The Secure Socket Layer is used to encrypt the data stream between the web server and the web client (the browser).
#    SSL makes use of what is known as asymmetric cryptography, commonly referred to as public key cryptography (PKI). With public key cryptography, two keys are created, one public, one private. Anything encrypted with either key can only be decrypted with its corresponding key. Thus if a message or data stream were encrypted with the server's private key, it can be decrypted only using its corresponding public key, ensuring that the
