Cyber Utils

I built these small cybersecurity utilities while learning — port scanning, hash cracking, password auditing, and PDF protection testing. Each tool is self-contained and focused on one thing, written to understand security concepts by coding them myself.

Designed for learning, lab practice, and authorized security testing only.

Tools

Tool	Description
port_scanner.py	TCP connect port scanner — scan a target IP or hostname across a port range.
hash_cracker.py	Hash identifier and cracker — auto-detects algorithm by hash length and cracks against a wordlist.
hasher.py	Password hasher — generate MD5, SHA1, SHA224, SHA256, SHA384, or SHA512 hashes.
pdf_cracker.py	PDF password auditor — generates targeted wordlists from personal info and tests encrypted PDFs.

Installation

git clone https://github.com/Utkarsh464/cyber-utils.git
cd cyber-utils
pip install -r requirements.txt

Usage

Port Scanner

python port_scanner.py
# enter target ip or hostname: 192.168.1.1
# start port: 1
# end port: 1024

Hash Cracker

python hash_cracker.py
# enter the hash path: hashes.txt
# enter wordlist path: wordlist.txt

Hasher

python hasher.py
# enter the password: mysecret
# choose algo (md5/sha1/sha224/sha256/sha384/sha512): sha256

PDF Cracker

python pdf_cracker.py
# PDF path: protected.pdf
# Name: John
# Mobile Number: 1234567890
# DOB (MMDDYYYY): 01011990

Requirements

• Python 3.8+
• pypdf — for PDF cracking (included in requirements.txt)

All other tools use only the Python standard library.
