encrypt and decrypt zip file

Script
var zip = new require('node-zip')();
var key = "10";
var fs = require('fs');

zip.file('hello.txt', key + ' hello world');


// generate a buffer and log it
var data = zip.generate({base64:false,compression:'DEFLATE'});
console.log(data.length);
console.log('data:',data);

// FIXME: here need to save the byte array into a file
//fs.writeFileSync('file.zip', data, 'binary');

// write the file
var zip = require('node-zip')(data, {base64: false, checkCRC32: true});


var Decrypt = require('./decrypt');

var decrypted = Decrypt(zip.file('hello.txt')._data.getContent(), key);
console.log(decrypted);
