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);    }  }}, 16.666666666666668);

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。
