光棍节游戏

前面几关就不提了

第八关开始，可以用firedebug来直接修改 或则将源码修改成这样

<form method="post" action="http://segmentfault.com/game/?k=638dd2a4096b4285ae9a3289513cc59c">
<input type="text" name="k" value="0741976f032afa8fb3a5209d4260a0eb" />
<input type="submit" name="k" value="0741976f032afa8fb3a5209d4260a0eb"  />
</form> 

这个是最通俗的做法

进入第九关,方法也是别样

既有用python来实现的也有用其他脚本实现的

这里我用java来实现下

将浏览器中的文字保存成文本，_替换成1保存成nine.txt

String filepath=CharIoTest.class.getResource("").getFile()+
            "/nine.txt";
            FileInputStream in=new FileInputStream(new File(filepath));
            byte b[]=new byte[1024];
            int i=0;
            while((i=in.read(b))!=-1){
                //String s=new String(b,0,i,"gbk");
                ss.append(b);
            }
            String str=ss.toString();
            byte temp[]=str.getBytes();
            BASE64Encoder base64Encoder =new BASE64Encoder();
            String bb=base64Encoder.encode(temp);
            System.out.println(bb);

打印出来的结果

这时候已经是base64的

接下来就是将这段字符写入到tar包中，然后解压文件就可以看到Key了

但是java没有提供操作tar的API，需要ant.jar来支持，先吃饭 

后续有时候完善代码
