Demonstrates how to get the public key in base64 format from a private key. VBScript

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

success = 0

' Load a private key from base64.
set bd = CreateObject("Chilkat.BinData")
success = bd.AppendEncoded("MHQCA....n0Q==","base64")

set privKey = CreateObject("Chilkat.PrivateKey")
success = privKey.LoadAnyFormat(bd,"")
If (success = 0) Then
    outFile.WriteLine(privKey.LastErrorText)
    WScript.Quit
End If

set pubKey = CreateObject("Chilkat.PublicKey")
success = privKey.ToPublicKey(pubKey)

pubKeyBase64 = pubKey.GetEncoded(1,"base64")
outFile.WriteLine(pubKeyBase64)

outFile.Close
