It can hide about 8k per image.<br /> <br /> The way it works is rather convoluted and hardware dependent:<br /> <br /> * capture a screenshot (320x200x256) to a .scr file (intercepts PRINTSCREEN key while in graphics mode 13h)<br /> * inject the hidden data into the .scr file<br /> * redisplay the .scr screenshot<br /> * use a third-party screen-capture program (not included) to take a screenshot and save it in a graphics file like a [[GIF]]<br /> <br /> Similarly, to extract the message<br /> <br /> * display graphics file<br /> * capture a screenshot to a .scr file<br /> * decode the message in the .scr file<br /> <br /> <br /> == Links ==<br /> * [http://www.nic.funet.fi/pub/crypt/steganography/stegodos.zip Download]<br /> * [https://www.researchgate.net/publication/317389194_Steganography_Encoding_text_and_Hiding_it_within_image Review]</div>
