shasum -a 256 FILE_NAME
On Windows
CRC32, CRC64, SHA256, SHA1, BLAKE2sp
Right-click the file in Windows Explorer and select CRC SHA > * (star)
The popup window will show the values, but unfortunately, there is no way to copy them to the clipboard. To be able to copy the hash value to the clipboard open a Bash window on the Windows computer and execute the Macintosh/Linux commands above.
To install Bash on a Windows workstation see the Git section of Install the DevOps development tools on Windows.
