SFTP Host Key Fingerprint

Demonstrates how to get the SSH server's host key fingerprint after connecting. AutoIt

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

$oSftp = ObjCreate("Chilkat.SFtp")

Local $sHostname = "sftp.example.com"
Local $iPort = 22

;  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.)
