java的MD5加密怎么改成C++的代码

import java.security.MessageDigest;

public class MD5andKL {

// MD5加码。32位

public static String MD5(String inStr) {

MessageDigest md5 = null;

try {

md5 = MessageDigest.getInstance("MD5");

} catch (Exception e) {

System.out.println(e.toString());

e.printStackTrace();

return "";

}

char[] charArray = inStr.toCharArray();

byte[] byteArray = new byte[charArray.length];

for (int i = 0; i < charArray.length; i++)

byteArray[i] = (byte) charArray[i];

byte[] md5Bytes = md5.digest(byteArray);

StringBuffer hexValue = new StringBuffer();

for (int i = 0; i < md5Bytes.length; i++) {

int val = ((int) md5Bytes[i]) & 0xff;

if (val < 16)

hexValue.append("0");

hexValue.append(Integer.toHexString(val));

}

return hexValue.toString();

}

// 可逆的加密算法

public static String KL(String inStr) {

// String s = new String(inStr);

char[] a = inStr.toCharArray();

for (int i = 0; i < a.length; i++) {

a[i] = (char) (a[i] ^ 't');

}

String s = new String(a);

return s;

}

// 加密后解密

public static String JM(String inStr) {

char[] a = inStr.toCharArray();

for (int i = 0; i < a.length; i++) {

a[i] = (char) (a[i] ^ 't');

}

String k = new String(a);

return k;

}

// 测试主函数

// public static void main(String args[]) {

//String s = new String("a");

// System.out.println("原始:" + s);

// System.out.println("MD5后:" + MD5(s));

// System.out.println("MD5后再加密:" + KL(MD5(s)));

// System.out.println("解密为MD5后的:" + JM(KL(MD5(s))));

//}

}
