question

Hi,

I've created a Python script here that properly uses our Developer Pay API. I'll be translating it into other languages in the future, but hope this guides you in the right direction for now.

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."}"
