any-steganography

How to use!!!

_require libs_

``javascript
const fs = require('fs');
const path = require('path');
const sg = require('any-steganography');
`

_define file paths, this can be from a file upload, etc_

`javascript
const file = path.join(__dirname, 'images', 'test.jpg');
const output = path.join(__dirname, 'images', 'test-with-message.jpg');
`

Let's write our message into a file

_first: read file_

`javascript
const key = '';
const buffer = sg.write(file, 'message', key);
fs.writeFile(output, buffer, (err) => {
if (err) {
console.log(err);
return;
}
});
`

Now let's make sure it worked as expected

_decode message_

`javascript
const buffer = fs.readFileSync(output);
const message = steno.decode(buffer, 'jpg', key);
console.log(message);
