SHA-1 is a cryptographic hash that has the property that it's virtually impossible with current technology to create a different file that returns the same hash as the one from any given file. If you know the hash that a file should have, and you verify that the file you have does indeed return that hash, then you can have extreme confidence that the file is authentic and exact in all respects down to the last bit, regardless of where and how you acquired the file.
