## Discussion

Discussion The CodeResources file that gets generated as part of the code signing process serves as the bundle’s seal. This file is a CFDictionary that contains a listing of all the files found within your bundle coupled with their respective hash values and a set of rule definitions. The type of object returned depends on which item in the dictionary had a problem. See macOS Code Signing In Depth for more information on the CodeResources file.
