The stack does (kind of) Steganography with an image, see https://en.wikipedia.org/wiki/Steganography.
The stack runs (offline) using LC 8.1.10/9.0.5/9.5 on MacOS > 10.12 and, using LC 8.1.10/9.0.5, on win 7/10 and linux (ubuntu1604). The goal was here to have a method that uses in a standard way only the alphadata of an image to hide embedded text. By that • we can use ANY base64 encoded data for embedding. we use as examples plainText, htmlText and an image. Other examples are styledText, rtfText or a svgPath. • we can clean the image from embedded code by simply resetting the alphadata of that image. That is, who knows that Steganograph embedded an object... ...can remove that object with a short script. ...can not read the embedded object as "clear" data, except he knows what YOU do with the object before embedding. We use compressing and base64Encoding of the embed-data. The decoding and encoding is done by a JS library via a browser widget.
