Why is there no MD5 sum? Because MD5 is partly broken and should not be used anymore. If you don't know how to compute SHA-1 and SHA-256 sums under Windows, a sha1sum tool is included in the CoreUtils package from the GnuWin32 project

This tool analyzes pdf files and checks if the cross reference (xref) entries match the objects in the file.

Example output:
