BCryptGenRandom 是 Windows CNG（Cryptography Next Generation） 提供的加密级安全随机数生成器（CSPRNG）接口。
随机源：内核熵池（多源熵：系统事件、硬件噪声等）
适用：密钥、IV、nonce、token、盐值等
安全级别：✔ 可用于生产加密
比起需要种子的随机数和JS中的Math.random更安全
NTSTATUS BCryptGenRandom(
BCRYPT_ALG_HANDLE hAlgorithm,
PUCHAR pbBuffer,
ULONG cbBuffer,
ULONG dwFlags
);调用：
BCryptGenRandom(0, 缓冲区指针, 缓冲区大小, 2)例如JS的：
CryptoJS.lib.WordArray.random(256)
//得出：
