QQ音乐sign计算
首先说明，所有加密接口都有非加密的替代接口，但是以后肯定是向加密接口发展，两个最基础的API是
https://u.y.qq.com/cgi-bin/musicu.fcg 支持加密和非加密
https://u.y.qq.com/cgi-bin/musics.fcg 仅支持加密
以上说多了，这篇主要是讲如何计算最新版的QQ音乐加密参数。
首先打开QQ音乐官网，F12打开开发者工具，我们随便找一条加密的链接
如图所示，我们可以看到这样一条链接
https://u.y.qq.com/cgi-bin/musics.fcg?-=getUCGI6892186109455234&g_tk=680034686&sign=zzadg51jzc4krod4v97bc3696a5f2740962d1e6c467957c88&loginUin=0&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8¬ice=0&platform=yqq.json&needNewCode=0&data=%7B%22detail%22%3A%7B%22module%22%3A%22musicToplist.ToplistInfoServer%22%2C%22method%22%3A%22GetDetail%22%2C%22param%22%3A%7B%22topId%22%3A4%2C%22offset%22%3A0%2C%22num%22%3A20%2C%22period%22%3A%222020-12-21%22%7D%7D%2C%22comm%22%3A%7B%22ct%22%3A24%2C%22cv%22%3A0%7D%7D
在链接中有个参数,我们的目标就是得到这个参数如何计算的方式
sign=zzadg51jzc4krod4v97bc3696a5f2740962d1e6c467957c88
点Initiator，找一下请求来源，点击来源的JS
在打开的JS里面查找sign找到如下图所示的区域，sign就是在这里得到的（格式化下js代码，否则看不清楚流程）在图中位置下断点，再刷新页面
https://y.gtimg.cn/music/portal/js/common/pkg/common_d9439fa.js?max_age=31536000:formatted
然后断在了这个地方，如果不是加密链接就放过，如果是，就步入
可以把鼠标放在变量上或者再控制台打印变量数据,如下图所示，我将请求的URL和请求参数打印了出来
//u.y.qq.com/cgi-bin/musicu.fcg?-=getUCGI4444074835099534&g_tk=680034686
{"detail":{"module":"musicToplist.ToplistInfoServer","method":"GetDetail","param":{"topId":4,"offset":0,"num":20,"period":"2020-12-21"}},"comm":{"ct":24,"cv":0}}
sign就是对请求参数加密之后得到的。
继续步入后，我们跳转到了下面这个JS里面，请求参数就是在这里加密的

var t = n.__getSecuritySign;
return delete n.__getSecuritySign,
t
});
然后在进入函数的返回出下断点，断在如下位置后，在控制台执行
r(f, e, c, l, t)
然后打印参数t,我们可以看到参数t里面出现了几个很特别的参数
CJBPACrRuNy7
97bc3696a5f2740962d1e6c467957c88
{"detail":{"module":"musicToplist.ToplistInfoServer","method":"GetDetail","param":{"topId":4,"offset":0,"num":20,"period":"2020-12-21"}},"comm":{"ct":24,"cv":0}}
看到97bc3696a5f2740962d1e6c467957c88 这样的数字，又是32位，可以大胆地猜测是md5，事实上，97bc3696a5f2740962d1e6c467957c88就是 把固定的字符串CJBPACrRuNy7与请求参数拼接起来之后的md5值
CJBPACrRuNy7{"detail":{"module":"musicToplist.ToplistInfoServer","method":"GetDetail","param":{"topId":4,"offset":0,"num":20,"period":"2020-12-21"}},"comm":{"ct":24,"cv":0}}
这个JS文件的作用就是用JS实现了一段MD5加密算法。
多次探索之后，我发现sign由以下规则生成
固定头zza+一段随机的小写字符串，由小写字母和数字组成，长度为10-16位+对固定字符串和请求参数取md5。这三部分拼接而成。
下面回到我们调试的地方，取消所有断电，放开运行，之后我们就得到了一个网址

计算出了sign后面就可以正常请求了。
Java代码实现
附上一段无名音乐中计算sign的代码，用Java实现

for (int i=0;i<ranLen;i++){

} catch (Exception e) {

}
String md5code = new BigInteger(1, secretBytes).toString(16);
for (int i = 0; i < 32 - md5code.length(); i++) {
md5code = "0" + md5code;
}
return md5code;

总结
核心的加密函数在以下JS文件中实现，这段JS主要就是实现了MD5算法，由于以前没接触过如何实现MD5算法，在分析这段代码上还是遇到了很大困难的，不过我们在实现过程中完全不必自己实现MD5加密算法，我们可以直接使用各个语言上的加密库实现MD5加密。
