本题最终 flag 为验证正确时的字符串加上逆向分析得到的所有生物特征值之和的 md5 (小写)。
比如，验证通过后显示的字符串为UniCTF{abcd}，分析得到的正确生物特征值为速度 11、抖动 33，生物特征值之和为 44，注意生物特征值通常不会太大，则最终的 flag 就是
tips：

题目描述更新为UniCTF{md5(UniCTF{abcd}44）}

Answer 1

从你贴出来的 verify_human 的 wasm 逻辑里可以直接看出来：

先从轨迹里算出 4 个“生物特征值”（都被截断成整数）并打包成 64-bit seed：
- A = floor(0.16 * len)（放在高 16 位）
- B = floor(totalDist / len)（放在次高 16 位）
- C = floor(2 * avgYJitter)（放在低 32 的高 16 位）
- D = floor(2 * avgXJitter)（放在最低 16 位）
然后用 LCG：
- seed = seed * 6364136223846793005 + 1442695040888963407 (mod 2^64)
- 每轮取 seed >> 56 作为 1 字节 keystream
- 去 XOR 解出 46 字节字符串（显示在页面上）

把 data 段里那 46 字节密文按上面 LCG 逆出来，能得到唯一通过前缀校验的特征值组合：

A=20, B=15, C=88, D=42
特征值之和：20 + 15 + 88 + 42 = 165

验证通过时显示的字符串是：

UniCTF{Hum4n_Err0r_1s_The_Tru3_P4ssw0rd_8x92a}

按题面更新：最终 flag 为 UniCTF{md5(验证字符串 + 特征和)}（md5 小写），即对下面字符串做 md5：

UniCTF{Hum4n_Err0r_1s_The_Tru3_P4ssw0rd_8x92a}165

得到 md5：

32f9b4c728f42db8ecd6d631cc950495

所以最终 flag 是：

UniCTF{32f9b4c728f42db8ecd6d631cc950495}
