请写一段脚本，要求如下：1.必须使用C语言或者C++;2.使用CMAC AES-128算法计算MAC值

当然，我可以帮你写一个使用CMAC AES-128算法计算MAC值的C语言脚本。下面是一个示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <openssl/aes.h>

#define AES_BLOCK_SIZE 16

void xor_blocks(unsigned char *a, const unsigned char *b) {
    for (int i = 0; i < AES_BLOCK_SIZE; i++) {
        a[i] ^= b[i];
    }
}

void left_shift(unsigned char *block) {
    unsigned char carry = 0;
    for (int i = 0; i < AES_BLOCK_SIZE; i++) {
        unsigned char next_carry = block[i] >> 7;
        block[i] = (block[i] << 1) | carry;
        carry = next_carry;
    }
    if (carry) {
        block[AES_BLOCK_SIZE - 1] ^= 0x87; // Rb value
    }
}

void aes_cmac(const unsigned char *key, const unsigned char *message, size_t message_len, unsigned char *mac) {
    AES_KEY aes_key;
    unsigned char k1[AES_BLOCK_SIZE];
    unsigned char k2[AES_BLOCK_SIZE];
    unsigned char subkey[AES_BLOCK_SIZE];
    unsigned char padded_message[AES_BLOCK_SIZE];
    
    memset(k1, 0, sizeof(k1));
    memset(k2, 0, sizeof(k2));
    
    // Generate subkey K1 and K2
    AES_set_encrypt_key(key, 128, &aes_key);
    AES_encrypt(k1, subkey, &aes_key);
    
    memcpy(k2, subkey, sizeof(k2));
    left_shift(k2);
    
    // Pad the message
    size_t padded_len = (message_len + AES_BLOCK_SIZE - 1) / AES_BLOCK_SIZE * AES_BLOCK_SIZE;
    memcpy(padded_message, message, message_len);
    memset(padded_message + message_len, 0, padded_len - message_len);
    
    unsigned char x[AES_BLOCK_SIZE];
    memset(x, 0, sizeof(x));
    
    for (int i = 0; i < padded_len; i += AES_BLOCK_SIZE) {
        xor_blocks(x, padded_message + i);
        AES_encrypt(x, x, &aes_key);
    }
    
    xor_blocks(x, k1);
    
    memcpy(mac, x, AES_BLOCK_SIZE);
    
    xor_blocks(x, k2);
    AES_encrypt(x, mac, &aes_key);
}

int main() {
    unsigned char key[AES_BLOCK_SIZE] = {0x2b, 0x7e, 0x15, 0x16, 0x28, 0xae, 0xd2, 0xa6,
                                         0xab, 0xf7, 0x15, 0x88, 0x09, 0xcf, 0x4f, 0x3c};
    unsigned char message[] = "Hello, world!";
    size_t message_len = strlen((char *)message);
    
    unsigned char mac[AES_BLOCK_SIZE];
    
    aes_cmac(key, message, message_len, mac);
    
    printf("MAC: ");
    for (int i = 0; i < AES_BLOCK_SIZE; i++) {
        printf("%02x", mac[i]);
    }
    printf("\n");
    
    return 0;
}

注意：这段代码使用了OpenSSL库来实现AES加密相关操作，因此需要确保已经安装了OpenSSL库并正确配置编译环境。你可以使用gcc编译这段代码，命令如下：

gcc cmac_aes.c -o cmac_aes -lssl -lcrypto

编译成功后，运行可执行文件 `cmac_aes` 将会输出计算得到的MAC值。请确保将 `key` 和 `message` 变量设置为你想要计算MAC的实际值。
