Java如何使用原生态java生成MD5值呢？

原生态字符串生成MD5的实现思路

借助MessageDigest对象即可生成字符串对应的MD5值

package com.java265.common.utils;
import java.security.MessageDigest;
 
/**
 * MD5加密工具类
 * @author java265
 *
 */
public class MyMD5Util {
    //盐，用于混交md5
    private static final String slat = "^&&*@#java265.com&*^";
    public static String encrypt(String dataStr) {
        try {
            dataStr = dataStr + slat;
            MessageDigest m = MessageDigest.getInstance("MD5");
            m.update(dataStr.getBytes("UTF8"));
            byte s[] = m.digest();
            String result = "";
            for (int i = 0; i < s.length; i++) {
                result += Integer.toHexString((0x000000FF & s[i]) | 0xFFFFFF00).substring(6);
            }
            return result;
        } catch (Exception e) {
            e.printStackTrace();
        }
 
        return "";
    }
}
