Function description: Calculate the hexadecimal Checksum of the file

Cross-platform checksum calculator supporting Ubuntu (AppImage) and Windows (exe).

Upgraded from CheckSum-Tool v1 (C# / .NET Framework → Python / PyQt6).

Features

Feature	Description
Byte-Sum Checksum	Sum of all bytes displayed as hex (same algorithm as v1)
MD5 Hash	MD5 hash calculation
SHA-1 Hash	SHA-1 hash calculation
SHA-256 Hash	SHA-256 hash calculation
Drag & Drop	Drag files directly onto the app
File Dialog	Open file browser with format filters
Copy to Clipboard	Copy any result with one click
Progress Bar	Visual progress for large file processing
Dark Theme	Modern, premium dark UI
Cross-Platform	Ubuntu + Windows

Requirements

• PyQt6

Quick Start

# Install dependencies
pip install -r requirements.txt

# Run the application
python src/main.py

Build

Windows (.exe)

scripts\build_windows.bat

Output: dist/CheckSum-Toolv2.exe

Linux (AppImage)

chmod +x scripts/build_linux.sh
./scripts/build_linux.sh

Output: dist/CheckSum-Toolv2 (standalone binary) or dist/CheckSum-Toolv2-2.0.0-x86_64.AppImage

Checksum Algorithm

The byte-sum checksum algorithm is identical to v1:

checksum = sum(all_bytes_in_file)
result = f"0x{checksum:X}"
