LunaModeler

LunaModeler是一款使用 Electron 开发的数据建模软件，这是一款收费软件，只有14天试用期。
发现了这篇文章，但是我使用没有生效。于是还是自己动手吧。

关于使用Electron开发的软件操作方法可以参考这里修改 NoSQLBooster for MongoDB 试用时间

源码已经摆出来了

思路

• 根据产品确认生成激活文件的位置。

• 随机生成一个合适的时间

• 写激活文件

• 调用执行

  • node index.js luna

实现

const crypto = require('crypto');
const moment = require('moment');
const fs = require('fs');

const encryption_key = 'BUA9VFNtbRQM85BODcCbXlrUtXXH3D3x';
const initialization_vector = '665UHDQ5qdBnI777';

function encrypt(text) {
  const cipher = crypto.createCipheriv('aes-256-cbc', Buffer.from(encryption_key), Buffer.from(initialization_vector));
  let crypted = cipher.update(text, 'utf8', 'hex');
  crypted += cipher.final('hex');
  return crypted;
}

function saveLicense(content, path) {
  const fileName = `${path}dts.asar.sys`;
  const encryptedContent = encrypt(JSON.stringify(content));
  fs.writeFileSync(fileName, encryptedContent);
}

// Get product name from argument
const productName = process.argv[2];
let pathName;

    console.log('Usage: node index.js <product_name>');
    console.log('Where <product_name> is one of: luna, meteor, perseid, galaxy, moon');
    process.exit(1);
    break;
}

let licPath = '';

/**
