<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
$pem = new CkPem();

// Load the PEM from a file.
// If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
$password = 'myPassword';
$success = $pem->LoadPemFile('../myPemFiles/myPem.pem',$password);
if ($success != true) {
    print $pem->lastErrorText() . "\n";

// Note: If the app already has the PEM pre-loaded in a string variable, then load it 
// by calling LoadPem instead.  
$pemContent = '... the PEM contents ...';

// Check for success as before..

// Convert to a JavaKeyStore object.
// The alias, if a non-empty string, will be applied to the 1st private key or 
// certificate.  All other keys and/or certificates will be assigned an auto-generated
// alias.

// This is the passord that will be required to access the created JKS.

    exit;
}

// Save the JKS to a file.  The password passed here is used for the keyed hash of the
// entire JKS file.  This may be different (if desired) than the password for individual private keys
// contained within the JKS.
