Picrypt

Using Picrypt you can hide messages inside of picture files. You can also protect them with a password. Also has full decryption to extract the messages any time you want. The picture will still be displayable as always and no noticable changes to it will show up. One of the best things about using this method is that when you hide a message inside an image, noone even knows its there. It is IMPOSSIBLE to tell that the image contains a message. Supports .bmp, .gif & .jpg. Built in converter also lets you open any format and save it as another. You could, for example, open Image1.bmp, then hide a message in it and save it as Image1.jpg and it will be output in standard .jpg format.
