// 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:
loo_Cert = create oleobject
