我需要用开关解密 128 ccm, 麦克风8字节, 但我的输出总是空的, 这是我的代码 :

void aes(){
unsigned char * aad = extochar("0841000CF635DFAB74F06D40A6A30090");


unsigned char * cipher = extochar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

// We will encrypt Psize bytes

// Time to decrypt the data into D

// Not sure if this is needed

int i;
printf("plaintext");
for(i=0; i<cipher_size; i++)
    printf("%.2x",plain[i]);
printf("
");

函数引文如下:

char * extochar(char* string)
{
    unsigned char * out = malloc(sizeof(unsigned char)*strlen(string)/2);
    int i;
    for (i = 0; i < strlen(string)/2; i++)
    {
        sscanf(&string[2*i], "%02x", (unsigned int *)(&out[i]));
    }
    return out;
}

平文本应该从
