This application uses the Least Significant Bit method with less success than the others. It also appends an EOF (end of file) character to the end of the message. Even with the EOF character, the message retrieved from the altered imaged most likely contained garbage at the end. The following is the original message (M1) and a portion of the message extracted from the image created with StegoDos:

Steganography is the art and science of communicating in a way which hides the existence of the communication. In contrast to cryptography, where the "enemy" is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganography is to hide messages inside other "harmless" messages in a way that does not allow any "enemy" to even detect that there is a second secret message present [Markus Kuhn 1995-07-03].
