File Information
Description

The following program hides a text encrypt in the pixels of an image in true colour by means of imperceptible changes to the human eye in the Colour.

The syntax is hidetc to hide the text in the image; in an interactive way the image (24 bits is selected) and the text (txt) that can be in any portfolio of the computer.
He requests us a password for encrypt (a word of up to 24 letters just by letters).

The syntax to recover the hidden text is seektc and you decrypt with the previous password.

Hi!
Thanks for sharing your work. I wish to ask you which algorithm you applied? As you know there are two general types which work either on spatial or frequency domains.

Because stenography is not the same thing that steganography

29 Sep 2002

I modified the algorithm that encrypted to be able to expand the space of keys to approximately 115 bits (a password of 24 letters)

30 Sep 2002

I eliminated two unnecessary image files (to reduce the size of the download).
