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

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

Note: This example requires Chilkat v11.0.0 or greater.

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

$success = 0;

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

$rsa = new COM("Chilkat.Rsa");

// First demonstrate importing a PEM public key:
$publicKeyPem = 'PEM public-key data goes here';
$pubkey = new COM("Chilkat.PublicKey");

$success = $pubkey->LoadFromString($publicKeyPem);
if ($success == 0) {
    print $pubkey->LastErrorText . "\n";
    exit;
}

$success = $rsa->UsePublicKey($pubkey);
if ($success == 0) {
    print $rsa->LastErrorText . "\n";
    exit;
}

// Demonstrate importing a PEM private key:
$privateKeyPem = 'PEM private-key data goes here';
$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 == 0) {
    print $privkey->LastErrorText . "\n";
    exit;
}

$success = $rsa->UsePrivateKey($privkey);
if ($success == 0) {
    print $rsa->LastErrorText . "\n";
    exit;
}

print 'OK!' . "\n";
