WhatsYourSign

Verifying a file's cryptographic signature can deduce its origin or trustability. Unfortunately on OS X there is no simple way to view a file's signature from the UI. WhatsYourSign adds a menu item to Finder.app. Simply right-, or control-click on any file to display its cryptographic signing information! WhatsYourSign is utility with a simple goal: from the UI, make it trivial to view any file's cryptographic signing information. A file or binary's cryptographic signature is important as it can determine its creator (Apple proper, a 3rd-party, etc). Moreover, it can help determine whether a file should be trusted. For example, binaries signed by Apple can (always?) be trusted, while files that are unsigned may be untrusted or even malicious.
