# HashGuard - Digital Evidence Integrity Verification System HashGuard is a web-based digital forensic system designed to verify the integrity of digital evidence using MD5 and SHA-256 hashing algorithms. ## 🔐 Features - Upload digital evidence - MD5 hash generation - SHA-256 hash generation - Integrity verification - Chain of Custody logging - Audit trail system - PDF report export - Role-Based Access Control (RBAC) ## 🛠 Technologies Used ## 🚀 Installation Clone repository: git clone https://github.com/DikaSetiawan45/hashguard-digital-forensics.git - Laravel 10 - PHP 8 - MySQL - TailwindCSS - Bootstrap - DomPDF --- ## 📌 Research Background This project was developed as a final thesis project in Information Systems focusing on: - Digital Forensics - Evidence Integrity - Cyber Security - Hash Verification --- ## ⚙️ System Workflow 1. Upload digital evidence 2. Generate MD5 & SHA-256 hash 3. Store baseline hash 4. Verify uploaded evidence 5. Compare hash values 6. Record verification logs --- ## 🧪 Integrity Verification The system compares: - Original MD5 hash - Original SHA-256 hash with the uploaded verification file. If both hashes match: - ✅ VALID If hashes differ: - ❌ MODIFIED --- ## 📊 Main Modules - Authentication & RBAC - Case Management - Evidence Management - Integrity Verification - Audit Trail Logging - PDF Reporting --- ## 👨‍💻 Author Dika Setiawan Information Systems Student Digital Forensics Enthusiast --- ## 📄 License MIT License
