(PHP Extension) Generate RSA Public/Private Key
PHP Extension example code showing how to generate an RSA public/private key.
<?php
include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
$rsa = new CkRsa();
// Generate a 1024-bit key. Chilkat RSA supports
// key sizes ranging from 512 bits to 4096 bits.
// Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.
// It takes a considerable amount of time and processing power to generate
// an 8192-bit key.
$success = $rsa->GenerateKey(1024);
if ($success != true) {
print $rsa->lastErrorText() . "\n";
exit;
}
// Keys are exported in XML format:
$publicKey = $rsa->exportPublicKey();
print $publicKey . "\n";
$privateKey = $rsa->exportPrivateKey();
print $privateKey . "\n";
?>
