WhatsYourSign adds a menu item to Finder to display cryptographic signing information of a file. Verifying a file's cryptographic signature can help deduce its origin or trustability, help to determine whether a file should be trusted. There is no simple way to view a file's signature from the UI, unfortunately, and that is why WhatsYourSign was created.
