(PHP ActiveX) Generate RSA Key and Export to Encrypted PEM
PHP ActiveX sample showing how to generate an RSA key and export to encrypted PEM. Note: This example requires Chilkat v11.0.0 or greater.
<?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");
// Generate a 1024-bit key. Chilkat RSA supports
// key sizes ranging from 512 bits to 4096 bits.
$privKey = new COM("Chilkat.PrivateKey");
$success = $rsa->GenKey(1024,$privKey);
if ($success == 0) {
print $rsa->LastErrorText . "\n";
exit;
}
$strEncPem = $privKey->getPkcs8EncryptedPem('myPassword');
// You now have the private key in an encrypted format,
// which may be (for example) saved to a database.
print $strEncPem . "\n";
?>
