• c++实现aes加密算法，对字符串进行加密

     我的blog中，已经写过一篇关于aes加密算法的调用。不过使用的参数必须时unsigned char类型。我们在
    编程中使用最多的char类型，我从网上下载了一个代码，追加了一部分代码。
        其主要功能进行实现unsigned char类型数据到char类型转化，将unsigned char结果与16进制字符串串之间的转化。代码如下：

         经过对代码的补充，这样我们在调用加密，解密时，就非常方便了，不用再考虑unsigned char类型字符串了。
    直接使用char类型字符串，就好了。调用如下：

    点击(此处)折叠或打开

    1. #include <QString>

    3. #include <stdio.h>
    4. #include "aes.h"

    6. int main(int argc, char *argv[])
    7. {
    8.     char mingwen[] = "http://www.baidu.com";
    9.     char miwen_hex[1024];
    10.     //char miwen_hex[] = "8FEEEFE524F8B68DC1FCA2899AC1A6B82E636F6D";
    11.     char result[1024];
    12.     unsigned char key[] = "xcysoft123";
    13.     AES aes(key);
    14.     aes.Cipher(mingwen, miwen_hex);
    15.     printf("%s\n",miwen_hex);
    16.     aes.InvCipher(miwen_hex, result);
    17.     printf("%s\n",result);
    18.     getchar();
    19.     return 0;
    20. }
    附件为使用qt creator开发工具，加载对aes加密算法的测试。
     AES.rar   

    补充：在QT开发环境中，我们经常使用的QString类型进行字符串的加密，解密。因此编写一个类。
    来进行方便的操作，代码如下：
    AesHelper.h的源代码

    1. #ifndef AESHELPER_H
    2. #define AESHELPER_H

    9. #include "aes.h"

    11. class AesHelper
    12. {
    13. public:
    14.     AesHelper();
    15.     ~AesHelper();
    16.     QString aesEncrypt(QString mingwen);

    18.     QString aesUncrypt(QString miwen);

    20. private:
    21.     AES *aes;
    22. };

    24. #endif // AESHELPER_H
    AesHelper.cpp的代码如下：

    10. {
