+
+输入任意账号、密码，正确填验证码，F12抓包。注意到访问`http://[URL]/rest/auth?answer=bmx8&captchaId=qxtd5hl5h8wz`，返回`{"status":"fail","code":"13","message":"登录失败: 用户名或密码不正确","data":null}`且无其他访问，确定为登录API。
+观察url参数，未发现账号密码；请求为GET不存在data。仔细观察请求体，注意到headers中有username和password，测试证明为账号密码。
+![登录API](https://oss.flt6.top/imgs/202506081117743.png?x-oss-process=style/init)
+显然账号密码加密，尝试直接重放请求失败，注意到headers中的`x-hmac-request-key`等，推测存在加密。
+
+## headers中的`X-hmac-request-key`等参数
+
+全局搜索关键字`x-hmac-request-key`，找到唯一代码
+```javascript
+{
+    var t = "";
+    t = "post" === e.method ? g("post") : g("get"),
+    e.headers = c()({}, e.headers, {
+        Authorization: sessionStorageProxy.getItem("token"),
+        "X-request-id": t.id,
+        "X-request-date": t.date,
+        "X-hmac-request-key": t.requestKey
+    })
+}
+```
+动态调试找到`g`的实现
+```
+function g(e) {
+    var t = function() {
+        for (var e = [], t = 0; t < 36; t++)
+            e[t] = "0123456789abcdef".substr(Math.floor(16 * Math.random()), 1);
+        return e[14] = "4",
+        e[19] = "0123456789abcdef".substr(3 & e[19] | 8, 1),
+        e[8] = e[13] = e[18] = e[23] = "-",
+        e.join("")
+    }()
+        , n = (new Date).getTime()
+        , r = "seat::" + t + "::" + n + "::" + e.toUpperCase()
+        , o = p.a.decrypt(h.default.prototype.$NUMCODE);
+    return {
+        id: t,
+        date: n,
+        requestKey: m.HmacSHA256(r, o).toString()
+    }
+}
+```
+
+注意到`o = p.a.decrypt(h.default.prototype.$NUMCODE);`未知，确定`h.default.prototype.$NUMCODE`是常量，且`p.a.decrypt`与时间无关，直接动态调试拿到解密结果`o=leos3cr3t`.
+
+其他算法实现均未引用其他代码，转写为python
+```python
+def generate_uuid():
+    hex_digits = '0123456789abcdef'
+    e = [random.choice(hex_digits) for _ in range(36)]
+    e[14] = '4'
+    e[19] = hex_digits[(int(e[19], 16) & 0x3) | 0x8]
+    for i in [8, 13, 18, 23]:
+        e[i] = '-'
+    return ''.join(e)
+
+def g(e: str):
+    uuid = generate_uuid()
+    timestamp = int(time.time() * 1000)
+    r = f"seat::{uuid}::{timestamp}::{e.upper()}"
+    secret_key = b"leos3cr3t"
+    hmac_obj = hmac.new(secret_key, r.encode('utf-8'), hashlib.sha256)
+    request_key = hmac_obj.hexdigest()
+    return {
+        "id": uuid,
+        "date": timestamp,
+        "requestKey": request_key
+    }
+```
+
+至此，使用上述`g`动态生成hmac后，其他内容不变条件下成功重放请求，可以拿到登录token。
+
+注意到账号密码均加密，尝试逆向。
+
+## 账号密码加密
+
+从`http://[URL]/rest/auth?answer=bmx8&captchaId=qxtd5hl5h8wz`请求的启动器中找到关键函数`handleLogin`
+![启动器](https://oss.flt6.top/imgs/202506081117170.png?x-oss-process=style/init)
+```javascript

+        return this.$alert(this.$t("placeholder.accountInfo"), this.$t("common.tips"), {
+            confirmButtonText: this.$t("common.confirm"),
+            type: "warning",
+            callback: function(t) {}
+        });
+    this.loginLoading = !0,
+    Object(m.y)({
+        username: d(this.form.username) + "_encrypt",
+        password: d(this.form.password) + "_encrypt",
+        answer: this.form.answer,
+        captchaId: this.captchaId
+    }).then(function(s) {
+        "success" == s.data.status ? (sessionStorageProxy.setItem("loginType", "login"),

+    }).catch(function(s) {
+        console.log("出错了:", s),
+        t.$error(t.$t("common.networkError")),
+        t.loginLoading = !1
+    })
+},
+```
+注意到
+```javascript
+username: d(this.form.username) + "_encrypt",
+password: d(this.form.password) + "_encrypt",
+```
+动态调试找到`d`的实现
+```
+var ....
+    , l = "server_date_time"
+    , u = "client_date_time"
+    , d = function(t) {
+    var s = arguments.length > 1 && void 0 !== arguments[1] ? arguments[1] : l
+        , e = arguments.length > 2 && void 0 !== arguments[2] ? arguments[2] : u
+        , a = r.a.enc.Utf8.parse(e)
+        , i = r.a.enc.Utf8.parse(s)
+        , n = r.a.enc.Utf8.parse(t);
+    return r.a.AES.encrypt(n, i, {
+        iv: a,
+        mode: r.a.mode.CBC,
+        padding: r.a.pad.Pkcs7
+    }).toString()
+}
+```
+显然`arguments.length`恒为1，故`s=l="server_date_time"`，`e=u="client_date_time"`，至此AES加密的参数均已知，python实现该AES加密后验证使用的AES为标准AES加密。
+故python实现账号密码的加密：
+```python
+def encrypt(t, s="server_date_time", e="client_date_time"):
+    key = s.encode('utf-8')
+    iv = e.encode('utf-8')
+    data = t.encode('utf-8')
+    
+    cipher = AES.new(key, AES.MODE_CBC, iv)
+    ct_bytes = cipher.encrypt(pad(data, AES.block_size))  # Pkcs7 padding
+    ct_base64 = b64encode(ct_bytes).decode('utf-8')
+    return ct_base64+"_encrypt"
+```
+
+关于验证码，`http://[URL]/auth/createCaptcha`返回验证码base64，提交时为URL参数，均未加密。
+至此，完成整个登录过程的逆向。
+
+## 其他API
+
+所有其他API请求headers均带有`X-hmac-request-key`，逻辑同上。URL参数中的token为登录API返回值。
+
