pip install solvertools

💡 Designed for ctfcli

This library helps you quickly write challenge solvers that integrate cleanly with ctfcli, making it easy to set up automated healthchecks for your challenges.

🛠 Requirements

Python 3.6+
pwntools

🧪 Example Healthcheck Solver

#!/usr/bin/env python3
from solvertools import connect_tcp, extract_flag

conn = connect_tcp("challenge.py")
conn.sendline(b"some input")
output = conn.recvall().decode()
extract_flag(output, r"flag\{.*?\}")
