If you want to calculate and compare the checksums of all files in a folder, please take a look at Checksum Folders in the Mac App Store, it is made specifically for this purpose.

Tip: Checksum Utility is made to calculate and compare single checksums. 100% hand crafted native Mac application.Substantial in-app help to let you know, what to do.If it matches OK is displayed and the exit code for the command is 0. The check argument generates the sha1 hash of filename and compares it with the value stored in filename.sha1. to check a sha1 hash use: sha1sum -c filename.sha1. A checksum is a sequence of numbers and letters that are. Navigate to the terminal and key in: sha1sum filename. You can test the correctness of Checksum Utility with zero-length checksums on your own. The OS X operating system offers two built-in methods to verify the checksum of a downloaded file.Guesses what algorithm a given checksum might be created with.checksum file and a manually entered checksum in any combination.
