Steganography using StegoMagic

It is a method of hiding data into other files. The most common practice is to hide some text information in pictures or audios. The reason behind this is such files like an image is made up of many bits, thus changing a few of them won't make any significant impact to human eye or human experience.

It is a software developed by 4 Indian programmers and is available freely. It uses a DES encrypted password to protect the data.
