Xml::Kit

Build Status Gem Version

Xml::Kit is a toolkit for working with XML. It supports adding XML Digital Signatures and XML Encryption.

Installation

Add this line to your application's Gemfile:

gem 'xml-kit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install xml-kit

Usage

# ./templates/item.builder

xml.instruct!
xml.Item ID: id do
  signature_for reference_id: id, xml: xml
  xml.Encrypted do
    encrypt_data_for xml: xml do |encrypted_xml|
      encrypted_xml.EncryptMe do
        encrypted_xml.Secret "secret"
      end
    end
  end
end
require 'xml/kit'

class Item
  include ::Xml::Kit::Templatable

  attr_reader :id

  def initialize(signing_key_pair, encryption_certificate)
    @id = ::Xml::Kit::Id.generate
    sign_with(signing_key_pair)
    encrypt_with(encryption_certificate)
  end

  def template_path
    current_path = File.expand_path(File.dirname(__FILE__))
    File.join(current_path, "./templates/item.builder")
  end
end

signing_key_pair = ::Xml::Kit::KeyPair.generate(use: :signing)
encryption_certificate = ::Xml::Kit::KeyPair.generate(use: :encryption).certificate
puts Item.new(signing_key_pair, encryption_certificate).to_xml

This will produce something like the following:

<?xml version="1.0" encoding="UTF-8"?>
