CalHash
CalHash is a utility that you can use to calculate and compare a file's checksum (also known as a message digest).
Since 2003, I have spent a lot of time developing these applications so that all Mac users can freely use them.
If you want to help me, you can donate.
WARNING:
There is a specific version of CalHash for each major operating system version.
Use the correct version, and don't try to use a version intended for an earlier operating system.
