question

Which class or libraries we need to include for this $rsa = new Crypt_RSA(); . I am trying to charge customer using credit , debit card in php framework cakephp 3+.

I got the prefix , modulus, exponent using below API URL

$url = 'https://sandbox.dev.clover.com/v2/merchant/'.$merchant_Id.'/pay/key';

But i stuck with the Encryption using class $rsa = new Crypt_RSA();. So my question is it compulsory to Encrypt the customer credit card can we send it without Encryption ?

If you decide to use 2.0 the classes changed a bit. Here's what I'm using

        $rsa = new RSA();


        $prefix = $this->key['prefix'];
        $modulus = $this->key['modulus'];
        $exponent = $this->key['exponent'];


        list($user_cc_mo,$user_cc_yr) = explode('/', $paymentData['exp']);
        $user_cc_no = str_replace('-','',$paymentData['cc']);
        $user_cc_cvv = (integer) $paymentData['cvv'];
        $user_zip = (integer) $profileData->zip;
        $first_6 = substr($user_cc_no, 0, 6);
        $last_4 = substr($user_cc_no, -4);
        // $user_cc_no = 4264281511118886;
        // $user_cc_cvv = 111;
        // $user_zip = 29368;
        // $first_6 = substr($user_cc_no, 0, 6);
        // $last_4 = substr($user_cc_no, -4);




        $stingToEnc = $prefix.$user_cc_no;
        //2.2. Generate an RSA public key using the modulus and exponent provided byGET /v2/merchant/{mId}/pay/key.
        $modulus = new BigInteger($modulus);
        $exponent = new BigInteger($exponent);


        $rsa->loadKey(['n' => $modulus, 'e' => $exponent]);
        $rsa->setEncryptionMode(RSA::ENCRYPTION_OAEP);


        //2.3. Encrypt the card number and prefix from step 1 with the public key.
        $ciphertext = $rsa->encrypt($stingToEnc);


        //3. Base64 encode the resulting encrypted data into a string which you will send to Clover in the “cardEncrypted” field.
        $cardEncrypted = base64_encode($ciphertext);

I have a question for you. It regards the OAuth. Can you get this endpoint to work? https://api.clover.com/oauth/authorize?client_id=XXXXXXXXXXXX&redirect_uri=https://XXXXXXXXXXXX.com/clover/authorize

Everything working fine now using phpseclib1.0.6 and only i am getting the currency error now :-
What will be valid currency i am using USD in currency parameters.

string(45) "{"message":"Please supply a valid currency."}"
