Ninam is a steganography tool for encoding and decoding a payload in a text by replacing white space characters. I created this program because I remembered when I was younger that I liked to hide a secret messages in my email using white text color printed on on a white background. This method is now more sophisticated.

How it works

All spaces in the text are recovered and replaced by other unicode space characters. If there is not enough space available, additional spaces will be added at the end. You can use 1-bit, 2-bit or 4-bit encoding. This means using 2, 4 or 16 white spaces. The larger the bitsize, the larger your payload can be, but at the risk of having slightly suspicious white spaces which doesn't work everywhere.
