Fathom OS: Cryptography & Breach Suite 🔐🏴‍☠️

A Python-based Object-Oriented Programming (OOP) module built for the Brainwavey / Fathom OS architecture. This repository demonstrates the complete lifecycle of cryptographic security, featuring both defensive encryption and offensive dictionary attack simulations.

🛠️ The Tools

1. The Defensive Protocol: SHA-256 Hasher (fathom_hasher.py)

A defensive security script that translates raw user string inputs into encoded bytes and generates an unbreakable 64-character hexadecimal SHA-256 hash.

• Core Concept: One-way cryptographic hashing and data encoding (utf-8).

2. The Offensive Protocol: Dictionary Attacker (hash_cracker.py)

An offensive security script that simulates a breach attempt on a target SHA-256 hash. It iterates through a local dictionary file (Passwords.txt), sanitizes the inputs, hashes each string, and compares them against the target payload to find a match.

• Core Concept: Automated brute-force/dictionary attacks, file handling (with open), and hidden data sanitization (.strip()).

🧠 Technical Skills Demonstrated

• Object-Oriented Design: Blueprint creation, state management, and encapsulation using Python classes.
• Data Sanitization: Cleaning invisible characters (\n) from external data sources to prevent mathematical algorithm failures.
• File I/O: Securely opening, reading, and closing external text files during active execution.

💻 Tech Stack

• Python 3
• hashlib (Standard Library)2. The generate_hash() method encodes the string and pushes the bytes through the SHA-256 algorithm.

3. The final output displays both the original text and the permanent, irreversible 64-character hash.
