1. 写在前面

又是一个忙碌的周末！其实最新有研究很多新的东西～但一直也没时间去写文章！上次发布的关于h5st参数的文章，是4.2版本的，批量商品价格查询。没几天全部更新到了4.7，现在小版本也是更新不断！不过小版本并不会受到太大的一个影响，本次文章更新的算法分析还原为最新4.7大版本下的4.7.2小版本～～

在这里插入图片描述

2. 加密分析

首先，接口请求的参数啥的就不再过多的去分析，主要看看核心点，目前全部VMP化，先把加密值拿出来，如下所示：

20240602103029809;5gtm6nz5ygggi9i8;f06cc;tk03w83c31b9341lMXgxWV9ScV9T5XO0c4lf3D7C4_8ewrP-y5CbOpQMxXJtPJoRrTYLui0MOiXN6oSSmP8Lwj0A6ghi;41cfe0ef53fa6ef42f0c090e80fac571be52efc6d951c5749036fb8edc892de3;4.7;1717295429809;TKmW3TyExztvDjBvYW30spstXUA9USbfpQA2Z0cZM9L1VhcxddydRM47xpgvr9gF1nxvSbHGC822PZqAj-untQlDF4PnJ0Hf1Ilqo8hI63Ymujt8frJjHYiCZK_VL5qL6uWRqrkdShS9QVb-UatJZSq8fRWDAxec-u0Ix4xN0XCKsQk4deD2JTt97sw4UlkGVqXbTOnXzyEQ-GTGuMi_gO-qtogbuof-tt5aNubxmj2ZcBxUGJOC9AkC1m6rZFKpSRCIob0WfsB6qSaH7fCv0-Ec7AwbiRbE_7C6-dAuo8ua3M8D4UdUNQAep_YCy4xEV_zuUUgKb3noPhz7rTiN1tS03CdM-n9YKsQaAEuJdlXhUQV8fY_p5xIpUsrVxOLCu7nZggE7nDk8PeheJO0dl8zjLad9Prk3hGJ0DQIeqffFGvzEemLTD52YgeDqWQHLXbk3

4.2之前是没有sign签名段的，可以看到整个加密参数的值跟上次的4.2是有区别的！同样经过多块组合拼接而成的，不过最新的以分号拆开大约分为8个部分了！

第一部分是一个时间格式的字符串，后续我们可以自行生成

第二部分则是fingerprint指纹，这个是需要算法生成的，第三部分可固定

第四部分tk则拼接多个参数加上指纹通过加密算法生成

第五部分签名Sign参数，通过对Token、fingerprint、时间戳、APPID

第六部分分别是算法的版本号以及时间戳！这个自行填写

第七部分时间戳

最后一部分的大长串则是上面参数经过最终AES加密生成

3. 算法还原

接下来这里作者按上面拆分出来的几部分，附上扣出来的算法并附上粗浅的讲解，第一部分的时间戳这里也给一下，主打的就是喂饭，时间参代码实现如下：

function timestampToFormat(timestamp) {const date = new Date(timestamp);const pad = (num, size) => String(num).padStart(size, '0');return `${date.getFullYear()}${pad(date.getMonth() + 1, 2)}${pad(date.getDate(), 2)}${pad(date.getHours(), 2)}${pad(date.getMinutes(), 2)}${pad(date.getSeconds(), 2)}${pad(date.getMilliseconds(), 3)}`;
}

第二部分我们需要还原的是FP的指纹，加密算法实现如下：

!function () {function t(e) {for (var t = "", r = 0; r < e.length;) {var n = e.charCodeAt(r++);t += n > 63 ? String.fromCharCode(32 ^ n) : 35 == n ? e.charAt(r++) : String.fromCharCode(n)}return t}var r = [t("SIZE"), "num", t("SPLIT"), "", t("DEFAULT"), t("CALL"), t("PUSH"), "pop", t("TOsTRING"), t("JOIN"), t("DEFAULT"), t("CALL"), t("REPLACE"), ""], n = Function.prototype.call,a = [2, 66, 17, 98, 16, 25, 286, 76, 37, 17, 58, 16, 13, 25, -2821, 25, -8150, 68, 25, 10976, 68, 91, 74, 17, 26, 16, 4, 78, 17, 73, 16, 13, 7, 91, 62, 17, 36, 16, 32, 88, 80, 0, 46, 80, 1, 76, 7, 68, 36, 16, 32, 25, -3718, 25, 2322, 68, 25, 1412, 68, 25, 575, 25, 6105, 68, 25, -6675, 68, 3, 88, 3, 25, 6578, 25, -9306, 68, 25, 2729, 68, 3, 80, 0, 46, 80, 1, 76, 68, 88, 68, 5, 17, 48, 70, 2, 52, 3, 76, 54, 17, 63, 17, 60, 93, 4, 40, 72, 76, 70, 5, 72, 25, 8402, 25, -5374, 68, 25, -3028, 68, 25, -8134, 25, -8213, 68, 25, 16362, 68, 65, 71, 17, 63, 17, 60, 93, 4, 40, 72, 76, 70, 5, 72, 25, 6175, 25, 4230, 68, 25, -10390, 68, 91, 79, 17, 67, 0, 33, 17, 30, 45, 95, 70, 6, 25, -5057, 25, 6375, 68, 25, -1283, 68, 63, 17, 49, 93, 4, 40, 87, 70, 7, 4, 25, 3357, 25, -5902, 68, 25, 2581, 68, 91, 3, 70, 8, 25, -8817, 25, 8543, 68, 25, 310, 68, 76, 76, 17, 87, 51, 25, 8755, 25, -8004, 68, 25, -751, 68, 34, 42, -56, 63, 17, 69, 93, 4, 40, 95, 76, 70, 5, 95, 14, 91, 33, 17, 95, 70, 9, 52, 3, 76, 29, 17, 27, 90, 39, 73, -2215, 73, -5180, 68, 73, 7395, 68, 94, 58, 50, 44, 49, 58, 76, 21, 0, 71, 4, 93, 70, 1, 4, 11, 79, 22, 84, 55, 58, 82, 73, -6046, 73, -7717, 68, 73, 13764, 68, 2, 60, 86, 11, 4, 70, 2, 11, 79, 22, 98, 3, 84, 39, 58, 27, 58, 79, 11, 36, 74, 91, -48, 4, 90, 20], o = zk, i = Array.from, c = Symbol, s = eh, u = Array.isArray, l = Og.exports;var generateVisitKey = function () {for (var e, t, o, i, c, s, u, l, p, v, d, _, x = n, S = a, A = [], E = 0; ;)switch (S[E++]) {case 2:A.push(y);break;case 3:_ = A.pop(),A[A.length - 1] -= _;break;case 4:null != A[A.length - 1] ?

第三部分的APPID直接取AID即可，这里不需要过多的分析

接下来就是第四部分的Token生成了，加密算法实现如下所示：

var getLocalTK;
!function () {function t(e) {for (var t = "", r = 0; r < e.length;) {var n = e.charCodeAt(r++);t += n > 63 ?

先调用genDefaultKey，入参是四个，分别是上面得到的Token、FP、APPID、时间戳+07拿到值，再调用签名函数getSign，入参数则是genDefaultKey的值加params，如下所示：

调用GEN_SHA256把body参数拿出来丢进去最后toString一下

接下来的六、七部分当然也就不需要给出思路了，一个版本号一个时间戳，大家自行生成即可！！！

最最最后面的AES，也是重点，话不多说，实现算法如下所示：

function _aesEncrypt(data) {var i = CryptoJS.AES.encrypt(data,CryptoJS.enc.Utf8.parse('_M6Y?dvfN40VMF[X'), // 密钥{iv: CryptoJS.enc.Utf8.parse(["01", "02", "03", "04", "05", "06", "07", "08"].join(""))});return CryptoJS.enc.Base64.encode(i.ciphertext)
}
