输入密码，分析抓包信息，如下：
可以初步判断是一个md5的密文数据，
使用全局搜索Search定位到加密位置下断点调试；并得到了已经加密后的密文， 我们如果想知道是怎么加密的，首先要拿到明文数据；
这时我们需要思考，明文密码在哪？它是在哪开始加密的？
我们首先在断点处一个一个值去看，发现n.pwd.substr(0, 16) 是明文密码，f()就是加密方法，那我们直接在断点位置选中f，跟到加密方法“f”里去； 或者在底部控制台输入f，也可以直接跟进去（注意：前提是必须在断点断住的情况下才能使用）
进入加密函数后，在当前位置下断点，并在下图右上角标记处点击（执行下一个函数），这样我们就能得到加密位置是n.exports; 那我们现在就需要找到n.exports的定义位置，看它是不是在一个方法里，最终定位到开始的位置；
在找代码的过程中，发现了如下图标记的位置，出现了“ }({ ” 这种类型的，可以判断这个加密方式是一个webpack类型的。
由于代码太多，我这里没有把代码复制到本地进行处理，所以显示不全。
既然知道了是webpack，那必定会有一个模块加载器，首先就要把模块加载器找到，并扒出来，为后面改写代码使用；如图：
!function(c) {
function e(e) {
for (var t, n, o = e[0], r = e[1], i = e[2], s = 0, a = []; s < o.length; s++)
n = o[s],
Object.prototype.hasOwnProperty.call(d, n) && d[n] && a.push(d[n][0]),
d[n] = 0;
for (t in r)
Object.prototype.hasOwnProperty.call(r, t) && (c[t] = r[t]);
for (l && l(e); a.length; )
a.shift()();
return p.push.apply(p, i || []),
u()
}
function u() {
for (var e, t = 0; t < p.length; t++) {
for (var n = p[t], o = !0, r = 1; r < n.length; r++) {
var i = n[r];
0 !== d[i] && (o = !1)
}
o && (p.splice(t--, 1),
e = s(s.s = n[0]))
}
return e
}
var n = {}
, d = {
"login/loginpage/loginpage": 0
}
, p = [];
function s(e) {
if (n[e])
return n[e].exports;
var t = n[e] = {
i: e,
l: !1,
exports: {}
};
return c[e].call(t.exports, t, t.exports, s),
t.l = !0,
t.exports
}
s.m = c,
s.c = n,
s.d = function(e, t, n) {
s.o(e, t) || Object.defineProperty(e, t, {
enumerable: !0,
get: n
})
}
,
s.r = function(e) {
"undefined" != typeof Symbol && Symbol.toStringTag && Object.defineProperty(e, Symbol.toStringTag, {
value: "Module"
}),
Object.defineProperty(e, "__esModule", {
value: !0
})
}
,
s.t = function(t, e) {
if (1 & e && (t = s(t)),
8 & e)
return t;
if (4 & e && "object" == typeof t && t && t.__esModule)
return t;
var n = Object.create(null);
if (s.r(n),
Object.defineProperty(n, "default", {
enumerable: !0,
value: t
}),
2 & e && "string" != typeof t)
for (var o in t)
s.d(n, o, function(e) {
return t[e]
}
.bind(null, o));
return n
}
,
s.n = function(e) {
var t = e && e.__esModule ? function() {
return e.default
}
: function() {
return e
}
;
return s.d(t, "a", t),
t
}
,
s.o = function(e, t) {
return Object.prototype.hasOwnProperty.call(e, t)
}
,
s.p = "/mpres/zh_CN/htmledition/";
var r = (t = window.webpackJsonp = window.webpackJsonp || []).push.bind(t);
t.push = e;
for (var t = t.slice(), o = 0; o < t.length; o++)
e(t[o]);
var l = r;
}({然后再找到加密代码，扣取出来（一定要扣全，从方法开始的位置），这里建议把代码全部复制到本地进行处理，比较方便。我这里就没有扣全（没有保存到本地）扣取后的代码如下：

function p(e, t) {
var n = (65535 & e) + (65535 & t);
return (e >> 16) + (t >> 16) + (n >> 16) << 16 | 65535 & n
}
function a(e, t, n, o, r, i) {
return p((t = p(p(t, e), p(o, i))) << r | t >>> 32 - r, n)
}

如图，我们是需要使用function s(e){}，在s方法定义结束后直接导出，最后补一个调用方法，再运行代码，可以出结果
