> AsyncSSH also has implementations of both ssh-ed25519 (in version 1.0.0 from April 2015) and ssh-ed448 (in version 1.16.0 from March 2019). See https://asyncssh.readthedocs.io/en/latest/changes.html for details. I tested the AsyncSSH ssh-ed448 support against the Erlang SSH library, which supports both ssh-ed25519 and ssh-ed448. Other implementations of ssh-ed25519 are listed at https://ssh-comparison.quendi.de/comparison/hostkey.html.

Thanks for the additional notes about implementation status!
