StegoMagic is an encryption software application designed specifically to help you hide files or messages in images, text files or audio elements. Files that embed private data do not generate any suspicion since they look the same on your system and have the same size, except for text files.
Steganography is a means of hiding data where secret messages are hidden within computer files, such as images, sound files, videos and even executable files, so that no one except the sender and receiver will suspect the existence of information hidden in it. Steganography may also involve the use of cryptography where the message is first encrypted before it is hidden in another file. In general, the messages appear to be something more, such as an image, sound or video, so that the transfer of secret data remains unsuspected.
