这这这，这谁顶的住啊！！！！！！！
emmmm，冷静冷静，我们先看看是不是真的乱码。
灵机一动，我们发现这里面全部是大小写字母和数字还有=号这样的东西。
不用猜，Base64.。。。。
啥是Base64?等等，我百度一下去。。。。。（斜眼笑.jpg）
Base64是网络上最常见的用于传输8Bit字节码的编码方式之一，Base64就是一种基于64个可打印字符来表示二进制数据的方法。可查看RFC2045～RFC2049，上面有MIME的详细规范。
Base64编码是从二进制到字符的过程，可用于在HTTP环境下传递较长的标识信息。例如，在Java Persistence系统Hibernate中，就采用了Base64来将一个较长的唯一标识符（一般为128-bit的UUID）编码为一个字符串，用作HTTP表单和HTTP GET URL中的参数。在其他应用程序中，也常常需要把二进制数据编码为适合放在URL（包括隐藏表单域）中的形式。此时，采用Base64编码具有不可读性，需要解码后才能阅读。
Base64由于以上优点被广泛应用于计算机的各个领域，然而由于输出内容中包括两个以上“符号类”字符（+, /, =)，不同的应用场景又分别研制了Base64的各种“变种”。为统一和规范化Base64的输出，Base62x被视为无符号化的改进版本。
嗯，以上那段非常非常专业的文字，出自百度之手，非本人！！！总而言之，言而总之！！！！
像上面那种就是Base64编码。。。。。
然后，我们就再次用一个在线解密的神奇网址，啊哈哈哈哈哈哈
就是这个https://base64.supfree.net/
我们复制Base64的编码，丢进那个网站，然后按下核按钮（Base64解密）
然后又出来一堆乱码，如下图：
不能呀，怎么肥四小老弟？？？？
啊哈，再看看题目，加密了多少次！！！！
so that，我们多按几下核按钮试试？
1，2，3，。。。。。。
最终在第20下的时候世界清净了。
不得不说出题人真的很用（丧）心良（病）苦（狂）呢！！！
好了，不bilibili，直接复制粘贴，提交！！！！
又是美滋滋的一天！！！！
