Identifying Files by SHA-256 Hash
Because filenames can easily be changed, the appliance generates an identifier for each file using a
Secure Hash Algorithm (SHA-256). If an appliance processes the same file with different names, all
instances are recognized as the same SHA-256. If multiple appliances process the same file, all instances
of the file have the same SHA-256 identifier.
