Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghid — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types. What Is Steganography?

Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems. It’s the first example of a growing category of money known as cryptocurrency. What makes it different from normal currencies? Bitcoin can be used to buy things electronically.

This puts some people at ease, because it means that a large bank can’t control their money. Who created it? A software developer called  Satoshi Nakamoto  proposed bitcoin, which was an electronic payment system based on ma
