Description
### 问题描述
用户使用Key和IV是HEX字符串的形式：
```C
#define KEY "60EaE9193555278880261c1995531f87B5097E494684F0CE1DBB50ABF625A82f" // strlen is 64
#define IV "631179b14B3D7D2E1E2D484360EAe919" // strlen is 32
```
请转化成数组，例如上述Key转化为`uint8_t array[] = {0x60, 0xea, 0xe9 ....} `，注意Key和IV中可能同时存在大写和小写字母，请正确处理它们。
