Training: Encodings I (Training, Encoding)

We intercepted this message from one challenger to another, maybe you can find out what they were talking about.

To help you on your progress I coded a small java application, called JPK.

Note: The message is most likely in english.

解题：

1.看到0和1，猜测是二进制askII 转换。

ASCII 码使用指定的7 位或8 位二进制数组合来表示128 或256 种可能的字符。

标准ASCII 码也叫基础ASCII码，使用7 位二进制数（剩下的1位二进制为0）来表示所有的大写和小写字母，数字0 到9、标点符号， 以及在美式英语中使用的特殊控制字符。

2.用给定的JPK进行Binary Format 转换，默认bitsperblock 是8，转换后发现多出1位不能整分，换用7，进行整分。

3.用给定的JPK进行Binary to ASCII转换即可。

This text is 7-bit encoded ascii. Your password is easystarter.
