Checksum Thing

Matthew Watkins

A native Swift and SwiftUI menu bar application for quickly calculating the checksum values of files. Calculates the following checksum types: MD5 SHA1 SHA256 SHA384 SHA512 Can optionally watch/monitor folders and dynamically process new files on arrival, checksumming them automatically in the background (useful for downloads, software build artefacts, etc). Allows for export of the internal database to a CSV file, for convenient bulk handling in other applications. Main features: Calculates checksum/digest values using a number of selectable algorithms Efficiently calculates multiple checksums in a single pass 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 14 and later releases Universal binary for both Intel and Apple Silicon hardware platforms Absolutely no adverts, tracking, calling home, or other privacy concerns
