SshHostKeys - conversion to OpenSSH

Dear support team,
i have na issue that I need to recover my public key from 'SshHostKeys', the key type is ssh-ed25519
I have foud it in registry in form of:
Name: ssh-ed25519@22:192.168.1.1
Value: 0x12ea765a......,0x91814064....
What kind of operation I need to do to recover it to form of OpenSSH ?

It is urgent because I lost my private key, but I have some backups but to recover them I need public key it in OpenSSH

Thank you in advance for any suggestion.

While it is most likely possible to convert the public key to OpenSSH format, we do not have a ready-made procedure for that.
I do not really understand, what do you need it for. Can you explain? There might be another way to do it.
