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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JavaKeyStore")
set jks = Server.CreateObject("Chilkat.JavaKeyStore")

jksPassword = "myJksPassword"

' A JKS private key entry consists of both the private key,
' it's associated certificate (which contains the matching public key
' within the X.509 of the certificate), and the certificates in the
' chain of authentication to the root.
' 
' Therefore, to add a private key entry to a JKS requires
' a Chilkat certificate object that has a private key and which also
' has the certificate chain (up to the root) available.

' There are many ways to get a Chilkat certificate object
' that contains (within it) the private key and the certificate chain
' This example will show two possibilities:
' (1) Where the cert and issuing root are provided in PEM format in .crt files,
' and the private key is also provided in unencrypted PEM format (.key file).
' (2) Where the cert, private key, and issuing root are provided in a single PFX.

' First for the .crt / .key files:
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Cert")
set cert = Server.CreateObject("Chilkat.Cert")

' Chilkat will automatically determine the format of the cert file and load it correctly.

    Response.End
End If

' Certificates required for building the chain of authentication can be
' added to an XML certificate vault object, and then provided as
' a source for obtaining certs when building the chain.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.XmlCertVault")
set certVault = Server.CreateObject("Chilkat.XmlCertVault")
success = certVault.AddCertFile("/mycerts/ca.crt")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( certVault.LastErrorText) & "</pre>"

' Now provide the associated private key to the certificate object.
' The Chilkat private key class provides methods for loading from many formats (both
' encrypted and unencrypted).
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.PrivateKey")
set privKey = Server.CreateObject("Chilkat.PrivateKey")

' to the Java keystore:

' Now let's add a new private key entry from a PFX that contains a single
' private key with associated cert and cert chain.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Pfx")
