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.

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.
