于是解密之后发现和python的一个官方文档相同。这个时候思路就开始跑偏了。。。当时自己想的是比较这两个文件，结果就是越来越偏。

看了别人的writeup之后才搞清楚base64原来有这么多的奥秘在里面。。。

事实上，这个题目利用的是base64加密后的字符串来藏字符。如果base64字符串后面有==时，说明前一个字符的后四位是任意的，既可以写入信息的。如果是=结尾的，前一个字符的后两位是任意的，可以写入信息。

然后还有一个地方在于base64的字符集，要对之前和之后的位置进行异或，再将其拼接起来，就是01字符串，转成字符串得flag。。。

代码：

import base64f=open("C:\\Users\\wangchong\\Desktop\\wangchong\\crypto100\\timian.txt")index='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'line=f.readline()while line:    line2=base64.b64encode(base64.b64decode(line))    line=line[0:len(line)-1]    if(line[-1]==line[-2]=='='):        x=line[-3]        x1=line2[-3]        res=str(bin((index.find(x))^(index.find(x1)))).replace('0b','00')[-4:]        if(len(res)==3):           res='0'+res        print (str(res)),                elif(line[-1]=='=' and line[-2]!='='):        x=line[-2]        x1=line2[-2]        print str(bin((index.find(x))^(index.find(x1)))).replace('0b','00')[-2:],    line=f.readline()

结果如下：

将这些字符拼接到一起转字符串，得到：
