hashverifier

HashVerifier is a versatile checksum utility for cross-platform file integrity verification. It supports 13 hashing algorithms, including MD5, SHA-1, SHA-256, SHA-512, BLAKE3, XXH3, and XXH128. The tool operates in command-line mode and via a GTK3 graphical interface. Key features include recursive checksum generation for directories, verification of existing files, real-time progress tracking, and support for symbolic links, hard links, and NTFS junctions. Generated checksum files are saved in UTF-8 encoding. The application is available for Linux, Windows, and macOS, with multiple packaging options for Linux and Windows, and experimental support for macOS. The GUI has persistent settings, saving preferences and column orders automatically.
