Calculate file checksums via Javascript
Interesting page:
https://md5file.com/calculator
It does MD5/SHA1/SHA256 calculations on local files, using Javascript.
Requires HTML5 file <input> support, but that is more common today.
No server support is needed, all calculations are done in the browser.
Give this as a proof of concept, the interesting next step would be to
have a page where users could check the integrity of their AOO
downloads. This could be used to check for suspected partial
downloads or for suspicions of modified versions.

I've changed the things it is worth it. I've not updated the files with
checksums of old and legacy OOo releases.
If you still see something that needs to be changed, just tell me or
update yourself.

Of course, internal link from openoffice.org pages to
http://www.openoffice.org/dev_docs/using_md5sums.html should be
rewritten to point to http://www.openoffice.org/download/checksums.html

This gets around 90 visits per day, almost all are referrals from
Google searches.
One external page linking in is this Nintendo Wii discussion page (!?):

Do you have any statistics (page hits) about the webpage? If not, then I
also favor to delete it from the index.
Thanks

Or we can delete the page we don't want and I can request its removal
from the Google index. That would be simpler, unless we have a lot of
3rd party links to the old page, which I doubt is the case.

Oh yes, checksums.html is much better, thanks.
Of course I had found the former through a search engine... which leads
me to think we should kill
http://www.openoffice.org/dev_docs/using_md5sums.html it and replace it
with a one-line page, linking to
http://www.openoffice.org/download/checksums.html . Does it make sense?

This file is outdated. Better to put it to the "checksums.html" which
directly linked from the download webpage which I've done now.

Interesting indeed. It solves what has been a major problem so far,
i.e., having to upload the entire file to have its md5sum checked via a
browser-based service. And it can calculate the hashes for a full
OpenOffice download in less than a minute, which is acceptable.
To start, we should definitely mention it in
