' 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:
set cert = CreateObject("Chilkat.Cert")

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