== Description A library for creating and verifying so-called »hash cash stamps«, i.e. proof of work as defined on hashcash.org. == Prerequisites This package requires Ruby 1.8 or later. == Installation instructions rake test (optional) rake install (non-gem) or rake install_gem (gem) == Synopsis require 'hashcash' # Create a new hash cash stamp s = HashCash::Stamp.new(:resource => 'hashcash@alech.de') puts s # Verify a given stamp s = HashCash::Stamp.new(:stamp => '1:20:060408:adam@cypherspace.org::1QTjaYd7niiQA/sc:ePa') s.verify('adam@cypherspace.org) == Known bugs Stamp creation is an order of magnitude slower than using the standalone hash cash program. This might not be fixed as I mainly use the library for verification. == Copyright (c) 2010 Alexander Klink == License Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
