文件的命名非常新颖，浅浅猜一下可能是和兔子和猫有关的算法，我们搜索一下

在CTF竞赛中提到的"兔子算法"通常指‌ Rabbit加密算法

Rabbit加密算法

Rabbit加密是一种流加密算法，通过非线性反馈实现加密。在题目中，加密后的文本需用在线工具进行解密，得到原始数据。 ‌
Base91编码

Base91是Base64的变种，采用91个字符的字符集进行编码。题目中txt文件名包含"91"提示，需用Base91解码工具处理加密内容。 ‌
Ook!密码

Ook!是一种由"!"、"."、"?"组成的简单密码语言，常见于CTF谜题。解码时需将加密内容复制到专用网站转换为可读文本。 ‌

直接打开链接，看到最后就发现了flag

Simple-Math

解压之后发现一个文件

查看大佬的解决方法，首先写一个1.py文件，然后进行运行

import hashlib
a='0011011001'
flag='XSCTF{'+hashlib.sha1(a.encode('utf-8')).hexdigest()+'}'
print(flag)

运行得出了flag

XSCTF{103c8041593b4b8e38971db283a7a773b0ffc2ee}

删除跑路-

解压之后发现文件

用随波逐流进行binwalk进行文件提取

发现提取文件

 flag{c28c424b-fd8c-45b9-b406-0a933b1ca7b1}

不确定，再看看

解压文件，发现.txt文件

解压文件，发现是一个音频文件

发现base64解码之后不太行，看大佬解码base64-- 解码20次-----base92

大佬代码，直接进入kali

首先把encode.txt拖进kali,之后再新建一个.py文件 python+.py文件名

import base64
 
with open("encode.txt", "r") as file:
    data = file.read()
 
for _ in range(20):
    data = base64.b64decode(data)
 
print(data)

运行之后

F#S<YRa[$*x7,>{F3DH5N/3.5+J6WD%P841JRN_i51F1Z!

得到flag值

flag{d0_y0u_l1ke_base92_!??!_by_Sh3n}

来自银河的信号

解压文件，发现.mp3文件

打开发现是一段噪音，大佬讲解是无线信号，下载rx-sstv软件，进行分析

RX-SSTV代表“接收图像慢扫描电视”的意思。慢扫描电视是一种通过无线电进行图像传输的技术，通常用于业余无线电领域。RX-SSTV可能指的是接收慢扫描电视信号的相关设备或软件

下载链接

RX-SSTV 2.0 Download (Free) - RXSSTV.exe

安装虚拟声卡链接

VSC 虚拟声卡，虚拟音频，变声器 - E2ESOFT

方法：

1.直接把.mp3文件发送到手机上，点击listing然后在手机上进行播放，注意周围不要有噪音

2.安装虚拟声卡

在rx-sstv中设置虚拟声卡

将输出的设备设置为100%

将三个全部选中

成功将.wav转换成图片，发现flag

steg没有py

解压文件，发现一张图片，相信看过这个电视剧的人都知道，这是谁了吧，

首先在kali中安装stegpy工具

pip3 install stegpy

git clone https://github.com/izcoser/stegpy.git

sudo python3 setup.py install

stegpy Do_you_like_misc.png -p

进行分解，密码就是文件名  Do_you_like_misc  ，不加后缀

查看_encrypt.txt文件

eyjd{4e71wf_H1uc3s_15_EEEEpwwl!!}

a,b∈(1,25]
a=x**2;
b=(x-2)**2;
print(a,b)   

这个题目的意思是，求a,b的值，发现当x=4时,a=16,b=4,当x=5,a=25,b=9,只有x=4,5时，才符合条件，我们进行仿射性解码

第二种

flag{4f71ne_c1ph3r_15_ffffunny!!}

第一种报错

提交flag发现报错，提示了一句，注意大小写

所以我们把在仿射密码解密之前是大写的位置，还改成大写，修改如下，进行提交

flag{4f71ne_C1ph3r_15_FFFFunny!!}
