Below is my php code for Encrypt card data:
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
//Code not working for line 7 and 8
//include('phpseclib3/Crypt/RSA.php');
//include('phpseclib3/Math/BigInteger.php');
include 'vendor/autoload.php';
use phpseclib3\Crypt\PublicKeyLoader;
use phpseclib3\Crypt\RSA;
use phpseclib3\Math\BigInteger;
use phpseclib3\Net\SSH2;
//card number
$card_number = "4242424242424242";
//Get Public Encryption Key from CDN ...
$PUBLIC_ENCRYPTION_KEYS_URL = "https://checkout.clover.com/assets/keys.json";
$TA_PUBLIC_KEYS_JSON_ARRAY = file_get_contents($PUBLIC_ENCRYPTION_KEYS_URL);
$TA_PUBLIC_KEYS = json_decode($TA_PUBLIC_KEYS_JSON_ARRAY,true);
//Parse the Base64 public key string (returned by the CDN). Obtain the modulus and exponent.
$pa_key = bin2hex( base64_decode( $TA_PUBLIC_KEYS['TA_PUBLIC_KEY_DEV'] ) );
$modulus = substr( $pa_key, 0, 512 );
$exponent = substr( $pa_key, -5 );
//Generate an RSA public key using the modulus and exponent values.
$rsa_public_key = PublicKeyLoader::load(
array(
'e' => new BigInteger( $exponent, 16 ),
'n' => new BigInteger( $modulus, 16 ),
)
);
//print_r($rsa_public_key); exit;
//Prepend the prefix value to the card number.
//Using the public key, encrypt the combined prefix and card number.
openssl_public_encrypt( '00000000'.$card_number, $encrypted, $rsa_public_key, OPENSSL_PKCS1_OAEP_PADDING );
$pan = base64_encode( $encrypted );
print_r($pan);
?>
It is generating an encrypted pan code. While using this code for encryption the "Please provide either raw pan or encrypted pan" error is coming. What am i doing wrong?
