What's Your Sign?
Check file origin and cryptographic signing details from Finder with this macOS utility.
About What's Your Sign?
What's Your Sign? adds a "Code Signing Info" item to the Finder right-click menu on macOS 10.15 and later. Selecting it opens a window with the file's cryptographic signing information, using a green lock for Apple signatures, a black lock for other valid signatures such as Mac App Store or Developer ID, and a red unlock icon for unsigned files or revoked certificates.
The window can also list MD5, SHA1, SHA256 and CDHash values, and show entitlements when present. Coverage of external or mounted drives is off by default, and the menu item may need the extension to be toggled off and on in System Settings.
