TP-Link路由器密文生成规则

对路由器的破解有点好奇，尝试了使用暴力破解的方法，于是在页面的js文件上上打断点，找到了生成对应的密文的方式。

本文记录TP-Link路由器的登录密码的加密方式，用python实现和js实现的版本

js的版本是页面中的原版

js版本：

function make_passwd(a, b, c) {
            var e = "", f, g, h, k, l = 187, n = 187;
            g = a.length;
            h = b.length;
            k = c.length;
            f = g > h ? g : h;
            for (var p = 0; p < f; p++)
                n = l = 187,
                p >= g ? n = b.charCodeAt(p) : p >= h ? l = a.charCodeAt(p) : (l = a.charCodeAt(p),
                n = b.charCodeAt(p)),
                e += c.charAt((l ^ n) % k);
            return e
        }
passwd = make_passwd("RDpbLfCPsJZ7fiv", "password", "yLwVl0zKqws7LgKPRQ84Mdt708T1qQ3Ha7xv3H7NyU84p21BriUWBU43odz3iP4rBL3cD02KZciXTysVXiV8ngg6vL48rPJyAUw0HurW20xqxv9aYb4M9wK1Ae0wlro510qXeU07kV57fQMc8L6aLgMLwygtc0F10a0Dg70TOoouyFhdysuRMO51yY5ZlOZZLEal1h0t9YQW0Ko7oBwmCAHoic4HYbUyVeU3sfQ1xtXcPcf1aT303wAQhv66qzW")

python版本：

    """根据输入来生成加密后的password"""
    e = ""
    a = "RDpbLfCPsJZ7fiv"
    c = (

    )
    g = len(a)
    h = len(b)
    k = len(c)
    f = g if g > h else h
    for p in range(0, f):
        n = 187
        l = 187
        if p > g:
            n = ord(b[p])
        elif p >= h:
            l = ord(a[p])
        else:

        e += c[(l ^ n) % k]
    return e
