Where would ldlinux md5 be found?

[lovix]

I'm using Rufus on a Windows computer for the purpose of producing a live Ubuntu USB. I have run MD5 check on the ISO, but Rufus informs me that 2 ldlinux files must be downloaded before I can proceed. The files download automatically through the Rufus app. I want to check the MD5 for those files. But I'm not finding that information anywher (and Rufus has not told me where the files came from, so I can't check for the MD5 there.)

Continuing with my tradition of answering my own questions...
Rufus is basically updating itself so that it can install the ISO. According to this page for Mint

And if you haven't asked the question as to whether Rufus has been verified, apparently Windows has done that for you.
