On second read, you're actually asking if a binary in a repo is the same as a binary on a website: to do that, just download both of them and hash them then compare the hashes:
$ sha256sum file1.zip | cut -f 1 -d ' ' | diff <(sha256sum file2.zip | cut -f 1 -d ' ') -
The above just uses bash to run sha256sum against "file1.zip" and "file2.zip" and pipes each result to diff. If they are not different you will see no output and $? will be 0. If they are different, you'll see the two different hashes printed on the command line. Note: if the above syntax is confusing or hard to replicate, you could always just compare hashes "by hand".
Thank you for the explanation very helpful, i will compare the hashes by "hand".
