关于javascript:实战解密热门js加密v6

没有废话间接上加密代码

解密后比照, 只贴小局部，爱护隐衷。

cacheTimer = setInterval(function () {drawCache();
}, 900);
drawTimer = setInterval(function () {if (window.draw_state) {console.log('1');
    shadowDraw();

    if (!window.fpscount) {window.fpscount = 0;}

    if (!window.fpstime) {window.fpstime = performance.now();
    }

    window.fpscount++;

    if (performance.now() - window.fpstime > app.zhenlv) {
      window.fps = window.fpscount;
      window.fpstime = performance.now();
      window.fpscount = 0;
    }

    ctx.textBaseline = 'top';
    ctx.textAlign = 'center';
    ctx.font = '50px \"Arial, sans-serif\"';
    ctx.fillStyle = 'red';

    if (window.fps) {ctx.fillText(window.fps, 80, 30);
    }
  }

解密思路

首先看结尾，很显著的 v6 加密的标记，收费的 v6 加密都有这个头，一看到这个就晓得是国内闻名的 v6 加密算法，是十分好识别的。只有是带有 jsjiami.com 的都是 v6 加密，因为这个就是他们的官网。

晓得了加密类型，而后依据不同的加密办法，去解密就 OK 了，这个免费版的还是比拟轻松的，如果是 vip 的话会辣手一些。
