codeblocks使用mbedtls加密字符串aes代码

以下是一个使用mbedtls库进行AES加密的示例代码：

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "mbedtls/aes.h"

void print_hex(const char *label, const unsigned char *buf, size_t len) {
    size_t i;

    printf("%s:", label);
    for (i = 0; i < len; i++)
        printf(" %02x", buf[i]);
    printf("\n");
}

int main() {
    const unsigned char key[16] = "0123456789abcdef"; // 128-bit AES key
    const unsigned char iv[16] = "0123456789abcdef";  // 128-bit IV
    const char *plaintext = "Hello, world!";
    unsigned char ciphertext[64] = {0};
    unsigned char decrypted[64] = {0};

    mbedtls_aes_context ctx;
    mbedtls_aes_init(&ctx);

    mbedtls_aes_setkey_enc(&ctx, key, 128);

    // 加密
    mbedtls_aes_crypt_cbc(&ctx, MBEDTLS_AES_ENCRYPT, strlen(plaintext), iv, (unsigned char *)plaintext, ciphertext);

    print_hex("Ciphertext", ciphertext, strlen(plaintext));

    // 解密
    mbedtls_aes_setkey_dec(&ctx, key, 128);
    mbedtls_aes_crypt_cbc(&ctx, MBEDTLS_AES_DECRYPT, strlen(plaintext), iv, ciphertext, decrypted);

    print_hex("Decrypted", decrypted, strlen(plaintext));

    mbedtls_aes_free(&ctx);

    return 0;
}

请记得在编译之前，确保已经安装了mbedtls库，并将其头文件和库文件正确地链接到项目中
