Add Checksum verification for Files (Convenience feature)

Already, right click that file, copy -> checksum

It calculates but I want in a way, so I input the checksum from download page and it says, Verified. If not, not verified, Download may be corrupted.

As title says, it is for Convenience. Instead of going to File manager and then, opening properties, etc.

I'm not entirely sure what you mean, but I will incorporate a feature similar to that.

https://download.opensuse.org/distribution/leap/15.5/iso/openSUSE-Leap-15.5-DVD-x86_64-Media.iso

The corresponding checksum file is

https://download.opensuse.org/distribution/leap/15.5/iso/openSUSE-Leap-15.5-DVD-x86_64-Media.iso.sha256

After the file is downloaded, try to fetch the checksum file from the HTTP server. If the checksum file exists, perform the verification process.

You could infer things from Free Download Manager's implementation abbut what I am trying to say.

Also Add verifying with ASCII based GPG keys.
