= Rack's hashed cookie-based session store

Rack::Session::HashedCookie is just a simple port to Rack of the Action Controller's cookie-based session store. All the praises to the Rails team, all the blames to me.

Remember that the session's content is just hashed to ensure that nobody will tamper with it, so do not store sensitive data in it.

== Basic usage

First, install it with:

$ sudo gem install rack_hashed_cookie_session

Here is how I use it with Sinatra. A rackup-file, a bit spiced up:

require 'rubygems' require 'sinatra' require 'rack/session/hashed_cookie'

root_dir = File.dirname(FILE)

Sinatra::Application.default_options.merge!( :views => File.join(root_dir, 'views'), :app_file => File.join(root_dir, 'app.rb'), :run => false, # Explicitly turn off standard cookie session store. :sessions => false, :env => ENV['RACK_ENV'].nil? ? :development : ENV['RACK_ENV'].to_sym )

use Rack::Session::HashedCookie, :secret => 'my long, difficultly guessable secret'

run Sinatra.application

The Sinatra application will use the session normally:

get '/' do session['user_id'] = 123456 session['just_a_string'] = 'Hello world!' erb :show_the_session end

template :show_the_session do "Hi! Reload the page to see the session:
<%= session.inspect %>" end
