Pwn4Sage's Guide

As we all know, we cannot use pwntools directly in SageMath.

In order to solve this problem, you can use Linux.

However, I realized that Cryptor does not need all the complex functions in Pwntools.

In fact, we always use some functions in Pwntools, such as recvline(), sendline() and other functions related to receiving and sending data.

Finally, when I found that socket can be used normally in SageMath, I decided to write a Simplified pwntools.

Pwn4Sage contains the following functions (if you don't know the specific use and details, you can check in the relevant documents of pwntools):

• send(msg)
• sendline(msg)
• recv(num)
• recvuntil(msg)
• recvline()
• recvline_contains(key_words)
• sendafter(delim, data, timeout)
• interactive()
• close()

Installation

This simple python script is available on PyPI and can be installed via pip.

• pip install Pwn4Sage

In the notebook of SageMath, you can use %pip install Pwn4Sage to install.

Usage

from Pwn4Sage.pwn import *
s = remote('39.105.144.62', 2022)
# print(s.sendafter(b'[+] Plz tell me XXXX:', b'1234\n'))
# print(s.recvline())

# s.sendafter(b'[+] Plz tell me XXXX:', b'1234\n'))
# print(s.recvline_contains(b'XXXX'))
s.interactive()
