(VBScript) Load an SSH Key from a File (Many Formats Supported)

Demonstrates how to load an SSH public or private key object from a file. The file can be in any of the following formats:

• OpenSSH private key
• OpenSSH public key
• PuTTY private key
• RFC 4716 public key

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.SshKey")
set sshkey = CreateObject("Chilkat.SshKey")

' First, use the LoadText convenience method to load a text file (of any SSH key format)
' into a string:
strKey = sshkey.LoadText("../mySshKeys/myKey.txt")

' Next, load the key into the SSH key object.

' If the key is an OpenSSH private key:
' (In actuality, the From* methods will automatically detect the format and load
' the key correctly.  For example, if a PuTTY private key is passed to FromOpenSshPrivateKey,
' it  will still load correctly.)
success = sshkey.FromOpenSshPrivateKey(strKey)
If (success <> 1) Then
    outFile.WriteLine(sshkey.LastErrorText)
Else
    outFile.WriteLine("Loaded OpenSSH private key.")
    WScript.Quit
End If

' If the key is an OpenSSH public key:
success = sshkey.FromOpenSshPublicKey(strKey)
If (success <> 1) Then
    outFile.WriteLine(sshkey.LastErrorText)
Else
    outFile.WriteLine("Loaded OpenSSH public key.")
    WScript.Quit
End If

' If the key is a PuTTY private key:
success = sshkey.FromPuttyPrivateKey(strKey)
If (success <> 1) Then
    outFile.WriteLine(sshkey.LastErrorText)
Else
    outFile.WriteLine("Loaded PuTTY private key.")
    WScript.Quit
End If

' If the key is an RFC 4716 public key:
success = sshkey.FromRfc4716PublicKey(strKey)
If (success <> 1) Then
    outFile.WriteLine(sshkey.LastErrorText)
Else
