# ClaimToken

ClaimToken encrypts and signs tokens to be used in a claim-based authentication system

## Installation

Add this line to your application's Gemfile:

    gem 'claim_token'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install claim_token

## Usage

    ClaimToken.configure do |config|
      config.cipher_type = "aes-256-cbc"  # this is the default
      config.shared_encryption_key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
      config.digest_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    end

To encrypt and encode a claim token:

    token = {"your_permissions" => "I HAZ THEM", "expires" => "2014-01-14T01:26:07Z"}
    ClaimToken.pack(token)

To decode and decrypt a claim token:

    packed_token = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX..."
    ClaimToken.extract(packed_token)
