(PHP ActiveX) RSA Encrypt with Modulus and Exponent
Demonstrates how to RSA encrypt with a given modulus and exponent.
<?php
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
$rsa = new COM("Chilkat_9_5_0.Rsa");
// Assuming you already have a base64 modulus and exponent,
// wrap it in XML like this:
$modulus = 'qMBRpdYrAy5aMmo31NErUizh5sbweguSmh4wlK6uJEIDl+kwTlROnE34KOFExeTbJSX0WygPi+vWl0yNq7buIMUKpytossAAWut5khO3CQJxTk7G2gnEPNUUXHiExGgNrLzcSLv8YIlfVALhoRWyC67KOL+a+3taNq3h+BHeWhM=';
$exponent = 'AQAB';
$xml = new COM("Chilkat_9_5_0.Xml");
$xml->Tag = 'RSAPublicKey';
$xml->NewChild2('Modulus',$modulus);
$xml->NewChild2('Exponent',$exponent);
// Encrypt with the public key.
$publicKey = $xml->getXml();
$success = $rsa->ImportPublicKey($publicKey);
$usePrivateKey = 0;
$plainText = 'message in a bottle';
$rsa->EncodingMode = 'base64';
$encryptedStrBase64 = $rsa->encryptStringENC($plainText,$usePrivateKey);
print $encryptedStrBase64 . "\n";
