Thank you very much every one for help!
This is the magic command, which I could not find.
For Anand: I need it for child zone delegation, like: gov.liberland.cz
Now it works:
Thank you again, regards

Hello Jakub,
You can use dnssec-dsfromkey command from Bind utils:
echo "liberland.cz. 3600 DNSKEY 257 3 13
ei9T3egqng+nlAHeNfF6BzggGCyvS2lU5ih2BZuvkzFGxkBdUJ0blgSiW5iYIROvAEHQv5Ls3sNPA9JIt8iRjg=="
./key.txt
dnssec-dsfromkey -f ./key.txt
liberland.cz
Or some online converter (e.g. filippo.io/dnskey-to-ds).
