"I'm sure the title of today's post probably put off more than a few purists who subscribe to the more exact definition that steganography is "the art of writing in cipher, or in characters which are not intelligible except to persons who have the key."

"Later in the week, we'll be looking at "really" hiding a message inside another message (or PDF, or picture, etc, as the case may be) so that it can't be encoded or decoded without a key. For now, we're going to look at just how easily one can pass a message along (inside a bitmap image) without using a key. The beauty of this method is that it's incredibly easy to implement and hard to notice if one isn't looking for it."
