File with to Checksums, Software NEED HELP

Hello Community,

I need help.
Here is a file that Contains 2 Checksums at the End. I need to know how this checksums are calculated with the content.

if someone have a solution, that checks whether the content has the same checksum, as the checksums at the end.

The Archive contains one license file, but I don’t know if it is necessary.

And the “C” is just a Prefix

But here is a Software that can read this Files and can Merge two Files to one with a New checksum. Maybe you can Reverse it

Edit: Also has Function that checks if Checksum is wrong
Found this via IDA Hex Ray 7.0 Decompiler
