(PHP Extension) Load PEM Public/Private Key into RSA Object

Demonstrates how to load a PEM key into the Chilkat RSA object.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?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 assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$rsa = new CkRsa();

// First demonstrate importing a PEM public key:
$publicKeyPem = 'PEM public-key data goes here';
$pubkey = new CkPublicKey();

$success = $pubkey->LoadFromString($publicKeyPem);
if ($success != true) {
    print $pubkey->lastErrorText() . "\n";
    exit;
}

$publicKeyXml = $pubkey->getXml();

$success = $rsa->ImportPublicKey($publicKeyXml);
if ($success != true) {
    print $rsa->lastErrorText() . "\n";
    exit;
}

// Demonstrate importing a PEM private key:
$privateKeyPem = 'PEM private-key data goes here';
$privkey = new CkPrivateKey();

// If the private key PEM is protected with a password, then 
// call LoadEncryptedPem.  Otherwise call LoadPem.
$success = $privkey->LoadPem($privateKeyPem);
if ($success != true) {
    print $privkey->lastErrorText() . "\n";
    exit;

$privateKeyXml = $privkey->getXml();

if ($success != true) {
    print $rsa->lastErrorText() . "\n";
