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

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rsa')
$rsa = new COM("Chilkat.Rsa");

// First demonstrate importing a PEM public key:
$publicKeyPem = 'PEM public-key data goes here';
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PublicKey')
$pubkey = new COM("Chilkat.PublicKey");

$success = $pubkey->LoadFromString($publicKeyPem);
if ($success != 1) {
    print $pubkey->LastErrorText . "\n";
    exit;
}

$publicKeyXml = $pubkey->getXml();

$success = $rsa->ImportPublicKey($publicKeyXml);
if ($success != 1) {
    print $rsa->LastErrorText . "\n";
    exit;
}

// Demonstrate importing a PEM private key:
$privateKeyPem = 'PEM private-key data goes here';
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PrivateKey')
$privkey = new COM("Chilkat.PrivateKey");

// If the private key PEM is protected with a password, then 
// call LoadEncryptedPem.  Otherwise call LoadPem.
$success = $privkey->LoadPem($privateKeyPem);
if ($success != 1) {
    print $privkey->LastErrorText . "\n";
    exit;
}

$privateKeyXml = $privkey->getXml();
$success = $rsa->ImportPrivateKey($privateKeyXml);
if ($success != 1) {
    print $rsa->LastErrorText . "\n";
    exit;
}

print 'OK!' . "\n";
