Add support for ed25519 keys

Hi there,
I shared a request a while ago, which is now hidden
in the backyard of the forum.

I’d like use a ssh ed25519 encrypted key for a sftp backup, but Updraft claims it’s an invalid format.

Would it be possible to add support for ed25519? It provides more secure and faster ssh accesss.

Thanks
