Checksum Checker is a PyQt6 desktop application for Linux that helps users verify file checksums against expected values and generate new checksums for local files.
It supports a broad range of hashing algorithms and presents the workflow in a simple graphical interface aimed at desktop users.
This is free and open source software.
Key Features
- Supports checksum algorithms including MD5, SHA-1, SHA-2, SHA-3, BLAKE2, SHAKE, and SM3.
- Offers a file browser and algorithm drop-down to simplify checksum operations.
- Displays color-coded results and visual icons to make successful matches and errors easy to spot.
- Can be installed as a Snap package or as a .deb package on Ubuntu-based distributions.
