(PHP Extension) Generate RSA Public/Private KeyPHP Extension example code showing how to generate an RSA public/private key.
<?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(); // 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"; ?> |
