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 devoted considerable time to developing these applications so that all Mac users can use them freely. If you would like to help, you can make a donation.

IMPORTANT:

There is a specific version of CalHash for each major operating system version.
Use the correct version, and don’t try to use a non-compatible version of CalHash.
