Checksum Thing 4+

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
