## Features

- **Wide Range of Algorithms**: Calculates multiple hashes in a single operation.
  - **Checksums**: CRC32, Adler-32
  - **Cryptographic Hashes**: MD5, SHA-1, SHA-2 (256, 384, 512), SHA-3 (256), BLAKE2b
- **User-Friendly Interface**: A simple GUI to select files and view results.
- **Efficient**: Processes large files in chunks, keeping memory usage low.
- **Cross-Platform**: Built with standard Python libraries, it runs on Windows, macOS, and Linux without extra dependencies.
- **Copy-Paste Ready**: Easily copy any hash value with a simple click and drag.
