# This document will help you setting up a Ruby on Rails development environment on Ubuntu and macOS.

# ---------------------------------------- Ubuntu ------------------------------------------------------ #
# To make sure we have everything necessary for Webpacker support in Rails, 
# we're first going to start by adding the Node.js and Yarn repositories to our system before installing them.
- sudo apt-get update
- sudo apt-get install git-core zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn

# Next we're going to be installing Ruby using one of RVM.

# Encrypts and Decrypts block of data given an encryption key and an
# initialization vector (iv).  Keys, iv's, and the data returned
# are all binary strings.  Cipher algorithm should be array [256, CBC],

# Pass nil if the encryption type doesn't use iv's (like ECB) or ignore it if you using.
