ssh-ed25519 fingerprint is invalid (in HostKeyEventArgs) with older servers

Fantastic library, amazingly easy to use - thank you!. The library version 2020.0.1 seems to fail to provide a correct fingerprint (MD5) for e.HostKeyName that equals to "ssh-ed25519". The HostKeyEventArgs (e.Fingerprint) contains 16 bytes that absolutely don't match OS X ssh (nor Windows 10 built-in ssh command output.) I even made sure to execute the command like below to ensure I am requesting the "ssh-ed25519" (to match what's reported by e.HostKeyName).

The ssh command: ssh admin@host-address -o HostKeyAlgorithms=ssh-ed25519 -o FingerprintHash=md5

Please help! The library works correctly with e.HostKeyName of "ssh-rsa", but "ssh.net" doesn't pick "rsa" when connecting to AWS Ubuntu hosts in 2021.

How to reproduce:

1. Connect to an AWS Linux host (Debian versions as recent as 2017),
2. The e.HostKeyName will be "ssh-ed25519"
3. The e.Fingerprint will "not" match the "ssh" command executed manually.

HostKeyEventArgs のエントリポイントから始め、ssh-ed25519 ホストキーに対して e.Fingerprint がどのように生成されるかを確認します。FingerprintHash=md5 を指定した記載の ssh コマンドを使って AWS Linux ホスト上で再現し、その後、ライブラリの 16 バイトのフィンガープリントと OS の出力を比較します。ssh-ed25519 のフィンガープリントがコマンドラインの結果と一致し、ssh-rsa の動作も正しいままであれば完了です。
