Short description of Picrypter 1.1 Demo: Picrypter is an encryption tool for 24-bit image files. This program uses the unique keys to encode/decode pictures. To make a picture hidden, Picrypter encode every single pixel of an image. In fact, it changes the color of them. The result is the indecipherable dump of pixels. So, the encoded file is still an image file and can be viewed in any picture viewer or editor. After decoding, the picture gets back without any distortion.
