'  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 = Server.CreateObject("Chilkat.Cert")

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