Description

I realize this may not be possible if the linked SSH library or android provide no support for it.

The algorithm has been around for a decade now. In the recent years it has been preferred over RSA by most new Linux installs. If possible, please add ed25519 support for HostKeyAlgorithms, KexAlgorithms and PubkeyAcceptedAlgorithms.

Thank you!!!!!!

Research direction

Locate the SSH sync implementation and its integration with the linked SSH library, then check whether Android and that library expose ed25519 support. Trace where HostKeyAlgorithms, KexAlgorithms, and PubkeyAcceptedAlgorithms are configured; done means supported ed25519 keys work for SSH sync or the dependency limitation is documented.
