How checksum line works in a manifest.json file used in shiny app?-CodePudding

You can see here a manifest.json file used to connect shiny app with API. I would like someone to explain to me the "checksum": "ed1521f080df2ef2e83a7d1c5fb944c1". What does that do ? I have seen that I can create reports with this for example like:

 "AQ_Report_Clean_Spanish.pdf": {
      "checksum": "ed1521f080df2ef2e83a7d1c5fb944c1"
    },

but what exactly does this id-like line does? If for example I want to create another report I have to change that "id" as well or just the report name like:

"AQ_Report_Clean.pdf": {
          "checksum": "ed1521f080df2ef2e83a7d1c5fb944c1"
        },

A more general answer not r & shiny specific:

It seems to be the checksum of the file mentioned above. You could verify by creating a md5 checksum (or some others) for the file here https://emn178.github.io/online-tools/md5_checksum.html.

The checksum helps to verify if the file could be downloaded/transferred as expected.
