MD5加密解密

附件是MD5的拷贝了很多别人的，都不好用，这个不错



下面的base64的，但是64的严格说来不加密算法
package test;

import java.io.UnsupportedEncodingException;
import java.util.zip.DataFormatException;
import java.util.zip.Deflater;
import java.util.zip.Inflater;

import javax.crypto.Cipher;
import javax.crypto.SecretKey;

import org.apache.commons.codec.binary.Base64;

public class chuanchuan {


     public static void main(String[] args) throws DataFormatException, UnsupportedEncodingException{

String source = "abcd<?>测试12323123123123123123123123123123123123123123123123";

byte[] inputTest = source.getBytes("UTF-8");
byte[] base64Data = Base64.encodeBase64(inputTest);
String target = new String(base64Data,"UTF-8");
System.out.println(target);

byte[] decode =  Base64.decodeBase64(target);
String outTest = new String(decode,"UTF-8");

System.out.println(outTest);

}
