Steganography is the art of writing in cipher, or in characters which are not intelligible except to persons who have the key.

This is an usable steganography application for concealing information in jpeg files by replacing the least significant bit of the RGB triplet with the provided text on a bit by bit basis. Since only the least significant bit is changed the resulting R, G, B bytes will be less than or more than unity resulting in a almost negligent amount of change in the color value.

Note: No error checks have been done to check if the text data to be embedded exceeds the available image data!
