md5`加密1：java简单实现

package md5testatest;import java.io.UnsupportedEncodingException;import java.security.MessageDigest;import java.security.NoSuchAlgorithmException;import sun.misc.BASE64Encoder;public class Md5testaaa {public static String EncoderByMd5(String str) throws NoSuchAlgorithmException, UnsupportedEncodingException{MessageDigest md5=MessageDigest.getInstance("MD5");BASE64Encoder base64en = new BASE64Encoder();String newstr = base64en.encode(md5.digest(str.getBytes("utf-8")));return newstr;}public static void main(String[] args) throws NoSuchAlgorithmException, UnsupportedEncodingException {// TODO Auto-generated method stubString str = "30对对对320917";System.out.println(str);System.out.println(EncoderByMd5(str));}}

其中BASE64Encoder的导入方式是从 http://blog.sina.com.cn/s/blog_5a6efa330102v8st.html 找来的
