MD5-SHA-Checksum-Utility is a user-friendly graphical tool designed to calculate and verify MD5, SHA-1, SHA-256, and SHA-512 checksums. The tool features a clean GUI with drag-and-drop file support, copy-to-clipboard functionality, and the ability to save results to a file. It also supports scanning folders to calculate hashes for multiple files.

• Drag and Drop Support: Easily drag files into the application to calculate checksums.
• Multiple Hash Algorithms: Supports MD5, SHA-1, SHA-256, and SHA-512.
• Copy to Clipboard: Quickly copy checksum results to the clipboard.
• Save Results: Save checksum results to a text or JSON file.
• Verify Hashes: Verify the integrity of files by comparing generated and provided hashes.
• Folder Scanning: Scan folders and subfolders to calculate hashes for multiple files.
• Save Folder Results: Save folder scan results as CSV, JSON, or text files.
