steganographie v0.0.1

Steganographie

About

This is currently a quite simple steganography library, allowing to conceal and reveal messages in pictures. There is currently only support for .png pictures, but I'm working on it.

Installation

npm install steganographie

Usage

Conceal function is used to compute the new picture containing the concealed message specified.

steganographie.conceal({
  input: 'absolute/path/to/img_source.png',
  output: 'absolute/path/to/img_conceal.png',
  method: 'simple',
  text: 'Super secret message, is the NSA looking for me?',
}, (err, res) => {
  if(err) {
    console.log('Hmm, there is an error with conceal: ');
  }
  console.log(res);
});

Reveal function is used to extract a message from a picture.

steganographie.reveal({
  input: 'absolute/path/to/img_conceal.png',
  method: 'simple'
}, (err, res) => {
  if(err) {
    console.log('Hmm, there is an error with reveal: ');
  } else {
    var message = res;
  }
});
