I am not familiar with the concept of checksums, but I've searched and, then, downloaded a program called "HashCalc" that seems to calculate checksums for different algorithms. This is the download I re-downloaded: "0ad-0.0.20-alpha-win32.exe", it is from 2016-03-31. This are the checksums for thirteen different algorithms:
