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

Dim sftp As New Chilkat.SFtp

Dim success As Boolean
success = sftp.Connect(hostname,port)

End If

// Get the classic MD5 fingeprint
Dim md5_fingerprint As String
md5_fingerprint = sftp.HostKeyFingerprint
System.DebugLog(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.)
