HashGuard - File Integrity Checker

HashGuard is a file integrity checker built with Python and Flask. It allows users to upload files and calculates multiple hash values (MD5, SHA-1, SHA-256) and CRC32 checksum to verify the integrity of the uploaded files. This tool can be used to detect if a file has been tampered with or corrupted.

Features

• File Upload: Simple file upload interface for users to choose a file to check.
• Multiple Hash Calculations: Supports the calculation of MD5, SHA-1, SHA-256 hashes, and CRC32 checksum.
• Copy Hash Values: Users can easily copy the hash values to their clipboard for further use.
• Error Handling: Displays error messages if no file is selected or if an issue occurs.
• Clear Results: Users can clear the results and reset the form to start a new check.

Technologies Used

• Flask: A lightweight web framework for Python used to build the backend.
• Hashlib: Python library for generating MD5, SHA-1, and SHA-256 hash values.
• Zlib: A Python module used to compute the CRC32 checksum.
• HTML/CSS: For the frontend layout and styling.
• JavaScript: For dynamic interactions such as displaying file names, handling errors, and copying hash values to the clipboard.
