(PHP ActiveX) Duplicate PHP RSA EncryptionDemonstrates how to duplicate the following PHP function.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Duplicate the following PHP code: // // public function encryptRSA($plainText,$rsaMOD,$pubKEY){ // $rsa = new RSA(); // $rsa->setEncryptionMode(RSA::ENCRYPTION_PKCS1); // $publicKey = [ // 'e' => new BigInteger($pubKEY,16), // 'n' => new BigInteger($rsaMOD,16) // ]; // // $rsa->loadKey($publicKey); // $ciphertext = $rsa->encrypt($plainText); // return bin2hex($ciphertext); // } // // $plainText="key=abcdefghijkmnopq&iv=abcdefghijkmnopq&h=12345678&s=12345678" // $rsaMOD="F0946D8F05604809E24B8CFFD30349CEA9E5F4D320BFD9E9AA1B088863F02C43E7997D37A3E27B4F8F359F1744DB6B20A437067C0D325A80660D12FF56A57673" // $pubKEY="010001" // We have the RSA modulus in hex $rsaMOD = 'F0946D8F05604809E24B8CFFD30349CEA9E5F4D320BFD9E9AA1B088863F02C43E7997D37A3E27B4F8F359F1744DB6B20A437067C0D325A80660D12FF56A57673'; // The RSA exponent in hex is "010001", which is 65537 in decimal. It's typically the exponent that is always used. $rsaEXP = '010001'; // Get the RSA modulus and exponent in base64. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $bdMod = new COM("Chilkat.BinData"); // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $bdExp = new COM("Chilkat.BinData"); $success = $bdMod->AppendEncoded($rsaMOD,'hex'); $success = $bdExp->AppendEncoded($rsaEXP,'hex'); // Build the XML representation of the RSA public key // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml') $xml = new COM("Chilkat.Xml"); $xml->Tag = 'RSAPublicKey'; $xml->UpdateChildContent('Modulus',$bdMod->getEncoded('base64')); $xml->UpdateChildContent('Exponent',$bdExp->getEncoded('base64')); // Load the RSA public key into a Chilkat public key object. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PublicKey') $pubkey = new COM("Chilkat.PublicKey"); $success = $pubkey->LoadFromString($xml->getXml()); // Setup the RSA object for encryption and do it.. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rsa') $rsa = new COM("Chilkat.Rsa"); $rsa->VerboseLogging = 1; $success = $rsa->ImportPublicKeyObj($pubkey); // Use PKCSv1.5 padding $rsa->OaepPadding = 0; // Encrypt and return the string as hex. $rsa->EncodingMode = 'hex'; $plainText = 'key=abcdefghijkmnopq&iv=abcdefghijkmnopq&h=12345678&s=12345678'; $cipherText = $rsa->encryptStringENC($plainText,0); if ($rsa->LastMethodSuccess == 0) { print $rsa->LastErrorText . "\n"; exit; } // Note: The PKCSv1_5 padding incorporates random bytes. Therefore, the RSA encryption will produce different results each time -- all of which are valid // and decrypt correctly to the same original text. print $cipherText . "\n"; ?> |
