SessionSecretGenerator

This is a super simple gem used to generate session secrets using a SecureRandom hex. This is useful if you're using a framework like Sinatra to build your webapp and want to make sure your sessions are secure.

Installation

$ gem install session_secret_generator

Usage

$ generate_secret

This will output a 128 character hexadecimal string that you can use as a session secret. You can then add

SESSION_SECRET=yourlonghexadecimalstringhere

to your .env file at the root of your project to keep your secret out of version control. You'll want to install the dotenv gem for this purpose.

There are 2 things you need to do to make sure this secret is read by your application.

1. Load your .env file from config.ru by adding

require 'dotenv/load'

2. Tell Sinatra about your secret by adding it to your configuration in your application controller. Adding these lines:

set :session_secret, ENV.fetch('SESSION_SECRET')

Here's a basic example in context:

require './config/environment'

class ApplicationController < Sinatra::Base

  configure do
    set :public_folder, 'public'
    set :views, 'app/views'
    register Sinatra::Flash
    enable :sessions
    set :session_secret, ENV.fetch('SESSION_SECRET') 
  end

  get "/" do
    erb :"/posts/index.html"
  end
end
