How do you create a checksum in Maven then output it to a text file?

Question

Still learning how to use Maven, and I was wondering if there is a way to do a checksum on the generated WAR file.

The Maven goal is package, and what I'm trying to achieve is to get a checksum value (of the packaged WAR file) put into a text file alongside the packaged file.

Thanks in advance!

Got it working with the below pom code and changing my Maven goal to verify

<dependency>
    ...
    <!-- CheckSum -->
