    <p>Have you tried this? <br>
    </p>
    <p><a class="moz-txt-link-freetext" href="https://apps.apple.com/us/app/md5-master/id1244747556?mt=12">https://apps.apple.com/us/app/md5-master/id1244747556?mt=12</a></p>
    <p>For those suggesting a more secure hash, I'm all for that, but
      the two-decades or more momentum is to use MD5s. We're not talking
      about James Bond spy stuff...we just want to know that Dropbox,
      our RAID array, whatever hasn't flipped a bit on us. I'll admit,
      I'm seeing virtually no glitches, but it adds peace of
      mind.             <br>
    </p>
    <p>The thing that most of the suggestions are missing is that there
      is a workflow issue that seems to have become standard in some
      quarters.</p>
    <p>From a current quad project I'm working on, are two
      filenames--the audio and the checksum file:<br>
      Whale_Piece_LF_Decoded_M24.wav<br>
      Whale_Piece_LF_Decoded_M24.wav.md5<br>
    </p>
    <p>The .md5 file contains one line of text</p>
    <p>E7F0905235FBDBFAFE56FD52313DFA11 *Whale_Piece_LF_Decoded_M24.wav</p>
    <p>This is produced by <a class="moz-txt-link-freetext" href="http://getmd5checker.com/">http://getmd5checker.com/</a> and it is a
      complete drag-and-drop Windows application for generating and
      verifying.</p>
    <p>Prior to that, I was using FastSum, but no longer recommend it as
      md5checker is so much nicer to use and seems more stable. FastSum
      puts some commented out lines in the .md5 file.<br>

    <p>Now, I don't know if that could operate in a compatibility window
      of some sort on a Mac.</p>
    <p>And although it doesn't list Win 10/11, the NT version works fine
      on W10.</p>
    <p>But I read David's original question to mean something to do the
      whole workflow.</p>
