whitespace encoder

Hides secret messages using whitespace only (invisible) characters.

In 2001, I was given a shareware CD with a program called SNOW on a shareware CD. SNOW was my first encounter with steganography and I've always wanted to implement my own take on SNOW's concept.

Usage

Only plaintext (ASCII only) files are supported at the moment, such as those made in notepad.exe

Encode

$ node whitespace.js [INPUT FILE] [OUTPUT FILE]

Decode

$ node whitespace.js [ENCODED FILE]
