RSA Encrypt Data

This method is used to RSA Encrypt the data with the provided public key.

Parameters

ParameterTypeMandatoryDescription
datastrYesThe data to encrypt, generally it is the card number or the card cvv.
public_keystrYesThe public key provided by PhonePe.

For Java SDK Version <= 1.0.1, the imports should be:
from phonepe.sdk.pg.payments

For Java SDK Version > 1.0.1, the imports should be:
from phonepe.sdk.pg.payments.v1

Example – RSA Encrypt Data

Java

import com.phonepe.sdk.pg.Env;
import com.phonepe.sdk.pg.common.http.PhonePeResponse;
import com.phonepe.sdk.pg.payments.v1.PhonePePaymentClient;

String merchantId = "<merchantId>";
String saltKey = "<saltKey>";
Integer saltIndex = "<saltIndex>";
Env env = Env.UAT;
boolean shouldPublishEvents = true;
PhonePePaymentClient phonepeClient = new PhonePePaymentClient(merchantId, saltKey, saltIndex, env, shouldPublishEvents);

String data= "105";
String publicKey = "<publicKey>";
String encryptedData = phonepeClient.encryptData(data, publicKey);

Returns

The encrypted data.

Custom – Saved Card

This method is used to initiate a Saved Card via the PhonePe PG Custom Checkout

Example (Custom – Saved Card)

Java
import com.phonepe.sdk.pg.Env;
import com.phonepe.sdk.pg.common.http.PhonePeResponse;
import com.phonepe.sdk.pg.payments.v1.PhonePePaymentClient;
import com.phonepe.sdk.pg.payments.v1.models.request.PgPayRequest;
import com.phonepe.sdk.pg.payments.v1.models.response.PgPayResponse;
import java.util.UUID;

String merchantId = "<merchantId>";
String saltKey = "<saltKey>";
Integer saltIndex = "<saltIndex>";
Env env = Env.UAT;
boolean shouldPublishEvents = true;
PhonePePaymentClient phonepeClient = new PhonePePaymentClient(merchantId, saltKey, saltIndex, env, shouldPublishEvents);

long amount = 100;
String merchantTransactionId = UUID.randomUUID().toString().substring(0,34);
String redirecturl = "https://merchant.com/redirectUrl";
String callbackurl = "https://www.merchant.com/callback";
String merchantUserId = "merchantUserId";

String authMode = "3DS";
String cardId = "cardId";
String encryptedCvv = "encryptedCvv";
Long encryptionKeyId = 1L;
PgPayRequest pgPayRequest = PgPayRequest.SavedCardPayRequestBuilder()
        .amount(amount)
        .merchantId(merchantId)
        .merchantTransactionId(merchantTransactionId2)
        .callbackUrl(callbackurl)
        .redirectUrl(redirecturl)
        .merchantUserId(merchantUserId)
        .authMode(authMode)
        .cardId(cardId)
        .encryptedCvv(encryptedCvv)
        .encryptionKeyId(encryptionKeyId)
        .build();

PhonePeResponse<PgPayResponse> payResponse = phonepeClient.pay(pgPayRequest);

Returns

The pay function returns a PgPayResponse object. With SavedCardInstrumentResponse object in data.
