Earlier this week I was looking into RESTFUL web services and how to create them, so I set myself a small project. The idea was to do something very basic, but that could be useful for someone rather than just a proof of concept. i had no real direction. With the news recently being about Apple locked in a battle with the FBI about whether or not they should be breaking their security for the FBI to access data on a particular iPhone, I started thinking about how much bad security I have seen in software applications over the years. From this, I decided to build a web service which would take a hash string, and provide the original string for that hash where possible.
