java转php加密和好密

java转php加密和解密
将UserJsonUtil类中的
encryptJsonUser（）加密，写成php的加密;
decryptJsonUser()解密，写成php的解密。

package com.test.moltest;

import java.util.Collection;
import java.util.Iterator;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.capinfo.crypt.Md5;
