(VBScript) Get the Certificate with Private Key from a Java KeyStore

See more Java KeyStore (JKS) Examples

Load a Chilkat certificate object from a Java KeyStore.

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

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

' Most of the time a .jks contains one certificate with it's associated private key.
' (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
' This example demonstrates how to get the certificate with private key such that it can be used
' by other Chilkat classes wherever a cert w/ private key is needed.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JavaKeyStore")
set jks = CreateObject("Chilkat.JavaKeyStore")
password = "secret"
success = jks.LoadFile(password,"qa_data/jks/test_secret.jks")
If (success <> 1) Then
    outFile.WriteLine(jks.LastErrorText)
    WScript.Quit
End If

' Make sure we have a private key.
If (jks.NumPrivateKeys < 1) Then
    outFile.WriteLine("No private key available.")
    WScript.Quit
End If

' -------------------------------------------------------------------------
' Get the certificate chain associated with the 1st (and probably only) private key in the JKS.
' chain is a Chilkat.CertChain
Set chain = jks.GetCertChain(0)
If (jks.LastMethodSuccess <> 1) Then
    outFile.WriteLine(jks.LastErrorText)
    WScript.Quit
End If

' cert is a Chilkat.Cert
Set cert = chain.GetCert(0)
If (chain.LastMethodSuccess <> 1) Then
    outFile.WriteLine(chain.LastErrorText)

    WScript.Quit
End If

' Verify again that this cert has a private key.
If (cert.HasPrivateKey() <> 1) Then
    outFile.WriteLine("Certificate has no associated private key.")

    WScript.Quit
End If

' We now have the cert object with it's associated private key, and it can be used in other Chilkat classes where needed.
' For example..

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Crypt2")
set crypt = CreateObject("Chilkat.Crypt2")
success = crypt.SetSigningCert(cert)
If (success = 0) Then
    outFile.WriteLine(crypt.LastErrorText)
    WScript.Quit
End If
