[vpsFree.cz: community-list] Is it possible to add a pub key in ed25519 form?

Hi My main ssh key uses ed25519. As a newcomer I tried to add it via the vpsAdmin menu Members "Add public key", but only got the error

Failed to save public key

Error message: create failed

key: invalid public key

Adding an ssh-rsa key worked fine. Or are there good reasons to forbit ed25519 keys? Best regards Niklaus
