Binary base64encode at CasperJS

Question

Is there a way to base64 encode binary data at CasperJS?
I mean something like that:

var pdfFile = require('fs').open('some.pdf', 'br');
var pdf = pdfFile.read();
var encoded = _some_func_for_encode(pdf);

Thanks.

You can certainly use native js method like btoa() and atob() .

Here is a very basic phantomjs script :

var fs = require('fs');
var filedata = fs.read('thefilehere');
var res = btoa(filedata);
console.log(res);
phantom.exit();

Base64 encoding/decoding is not so complex and you can easily find js function such as this one.
