文件的加密解密代码主要是针对于DES和3DES MD5加密解密算法的功能实现

package com.zrx.struts.action;
import java.io.File;
import java.io.FileOutputStream;
import java.io.PrintWriter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.zrx.Util.MD5Util;
import com.zrx.struts.form.Md5Form;

public class Md5Action extends Action {

	@Override
	public ActionForward execute(ActionMapping arg0, ActionForm arg1, HttpServletRequest arg2, HttpServletResponse arg3) throws Exception {
		
		Md5Form form =(Md5Form)arg1;
		String filename=form.getFilename();
		
		MD5Util m = new MD5Util();
		String md5str= m.encoder(new File(filename));
		
		arg2.setAttribute("md5", md5str);
		
		FileOutputStream fis = new FileOutputStream("D://md5.txt");
		PrintWriter out = new PrintWriter(fis);
