Checksum Thing

A native Swift and SwiftUI menu bar application for quickly calculating the checksum values of files. Calculates MD5, SHA1, SHA256, SHA384 and SHA512 checksums. Can optionally watch/monitor folders and dynamically process new files on arrival, checksumming them automatically in the background (useful for downloads, etc). Can export the database to a CSV file for convenient bulk handling in other applications. • Calculates checksum/digest values using a number of selectable algorithms • Explicitly add files or drag/drop content onto the main window for processing • Click on filenames to view the calculated checksum values • Clicking on a displayed checksum value will copy it to the clipboard • Option to export database content and checksum values to CSV file • Uses hardware acceleration for cryptographic functions on supported Macs • Fully sandboxed macOS application with minimal permissions • Optional audio feedback when operations start or complete • Runs in the background from the macOS menu bar, hiding the dock icon • Animated menu bar icon shows when background operations are in progress • Written purely in Swift and SwiftUI for macOS 11 and later releases • Universal binary for both Intel and Apple Silicon hardware platforms • Absolutely no adverts, tracking, calling home, or other privacy concerns
