ReconForge

A modular CTF toolkit for automated crypto analysis, binary reconnaissance, and web fingerprinting — built for speed during competitions.

Modules

Module	Description
crypto/	Cipher identification (Base64, Hex, Caesar, Vigenère) & automated decryption
binary/	Binary recon report + high-speed C pattern scanner
web/	HTTP fingerprinting, tech stack detection, WAF detection, JWT decoding
scripts/	Bash executors to run each module from the command line

Setup

make setup

Usage

Crypto

./scripts/ctf_crypto.sh <ciphertext_file_or_string>

Binary

./scripts/run_binary.sh <binary> [pattern]

Web

./scripts/run_web.sh <url>
