  • 🀝 Collaboration goals: security research, vulnerability assessments, and tools for security analysis & digital forensics
  • πŸš€ Learning journey: threat detection, ethical hacking, and critical infrastructure protection via hands-on labs (Hack The Box, Cisco, OPSWAT)
  • πŸ” Ask me about: security tools, vulnerability reporting, penetration testing basics, Android vulnerability testing, and malicious IP analysis
  • ✍️ Fun fact: I enjoy writing about security challenges and sharing technical insights with the community

πŸ” Cybersecurity Mini-Projects

Hands-on security tools built to practice core concepts β€” networking, cryptography, auth, and threat detection. Each repo includes a working CLI, README, and (where relevant) safety/usage notes.

Project Description
network-port-scanner Multi-threaded TCP port scanner for auditing your own hosts/network
ip-address-info-finder Looks up geolocation & network info (ISP, ASN, timezone) for an IP address
url-safety-checker Heuristically rates a URL's phishing/scam risk, with optional live TLS check
phishing-website-detector Scans a webpage's content for phishing indicators (fake login forms, brand impersonation)
login-authentication-system Login system demonstrating salted PBKDF2 password hashing and brute-force lockout
file-encryption-decryption-tool Encrypts/decrypts files using Fernet (AES) with passphrase-based key derivation
caesar-cipher-text-encryptor Caesar cipher tool with encrypt, decrypt, and frequency-analysis brute-force crack modes
password-strength-checker Scores password strength and gives actionable feedback
password-generator Generates cryptographically secure random passwords

More in progress: file integrity checker, keylogger detection, signature-based malware scanner, packet sniffer, Wi-Fi scanner, DNS lookup, website security scanner, and system log analyzer.
