NODE.js Grabbing RSA KEY of TIBIA-10

[Snavy]

I have followed This Tutorial and did everything that it says. But I am receiving an error message which im not able to find a solution for:

Nedims-Air:shivera nedimkanat$ node findRSAkey.js

test1 // This was to see where the code was giving error
buffer.js:191
    throw new TypeError('"encoding" must be a valid string encoding');
    ^

Error line is 24
in This file:

// import dependencies
var fs = require('fs-sync');
var binstring = require('binstring');

// define all options here
var options = {
    // where to save RSA key
    outputFile: 'RSA.txt',

    // where is your Tibia client
    inputFile: '/Users/nedimkanat/Downloads/Tibia/Tibia.exe',
    // convert binary file to human readable utf8 format
    conversionOptions: { in: 'bin', out:'utf8' },

    // this is most important, it assumes that RSA key is string of 245 digits long or
    // longer and no other string is so long like this one,
    // if there will be more matches like this we have a problem
    RSApattern: /\d{245,}/g
};

// humanize
console.log("test1");
var humanData = binstring(fs.read(options.inputFile), options.conversionOptions);

console.log("test2");
// extract RSA with RegEXP
var RSA = humanData.match(options.RSApattern);

// assume only 1 match found
try {
    RSA[0] ? RSA = RSA[0] : null;
} catch(Error) {
    console.log('no match');
}
// save it to output file
fs.write(options.outputFile, RSA);

// confirm by outputing result to console
console.log(RSA);

after a fast read on a forum I found out whats the problem.
binstring conversion options are wrong (just one), you can check it here, anyways the solution is this
change

conversionOptions: { in: 'bin', out:'utf8' },

to

conversionOptions: { in: 'binary', out:'utf8' },

@StreamSide Thanks alot!
