' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim ssh As New ChilkatSsh

Dim hostname As String
hostname = "ssh.example.com"
Dim port As Long
port = 22
Dim success As Long
success = ssh.Connect(hostname,port)
If (success <> 1) Then
    Debug.Print ssh.LastErrorText
    Exit Sub
End If

' Get the classic MD5 fingeprint
Dim md5_fingerprint As String
md5_fingerprint = ssh.HostKeyFingerprint
Debug.Print md5_fingerprint

' Sample output:
' ssh-rsa 3072 21:b0:d8:41:4e:ef:78:10:20:af:01:b7:71:5d:eb:94

' Starting in Chilkat v9.5.0.92, we can also get the SHA256 fingerprint.
' (it is also possible to get fingerprints using other hash algorithms such as SHA384, SHA512, etc.)
