Checksum compare

[BloodyIron]

I would really like it if we had a field where we could dump the checksum it's supposed to be, then generate the checksum, and have it compare "match!" "do not match!" kind of thing.

Much easier than manually comparing the entire string.

Just a small convenience, would be appreciated! :D

There is a really convenient standard for checksums in a directory called BagIt:

• https://en.wikipedia.org/wiki/BagIt

It is described in an RFC:

• https://datatracker.ietf.org/doc/html/rfc8493

If we had support for reading BagIt metadata, and comparing it to the actual checksums that would be wonderfull. We could optionally create BagIt metadata files (with lets say a button in the Nextcloud interface).

If this sounds interesting, I would be willing to start working on a PR for adding this?
