no support for elliptic curve (ssh-ed25519) "Failed to negotiate key exchange algorithm"

[fgodskesen]

connecting to SSH servers that only support ssh-ed25519 fails with

PS C:\Users\flgod> $s= New-SSHSession -ComputerName 10.111.20.10 -Credential $cred
New-SSHSession : Failed to negotiate key exchange algorithm.
At line:1 char:5

• $s= New-SSHSession -ComputerName 10.111.20.10 -Credential $cred

• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  

  • CategoryInfo : SecurityError: (Renci.SshNet.SshClient:SshClient) [New-SSHSession], SshConnectionException
  • FullyQualifiedErrorId : SSH.NewSshSession

Support for ed25519 is included in SSH.NET since January, so perhaps a merge from SSH.NET is possible?
sshnet/SSH.NET#496
