For both integrity & data-authenticity verification before sending data to the API, you need to
calculate a checksum of all the data that you send to MobiKwik Payment Gateway. We use an
HMACSHA-256 algorithm to calculate the checksum of ALL data that is posted to the API. We require data to be posted to our server in the NVP (Name-Value Pairs) format.

HMAC SHA 256 Algorithms

public static String calculateChecksum(String secretKey, String allParamValue) throws Exception { 
    byte[] dataToEncryptByte = allParamValue.getBytes();
    byte[] keyBytes = secretKey.getBytes();
    SecretKeySpec secretKeySpec = new SecretKeySpec(keyBytes, "HmacSHA256");
    Mac mac = Mac.getInstance("HmacSHA256");
    byte[] checksumByte = mac.doFinal(dataToEncryptByte);
    String checksum = toHex(checksumByte);
    return checksum;
static function calculateChecksum($secret_key, $checksumString) {
    $hash = hash_hmac('sha256', $checksumString , $secret_key);
        $checksum = $hash;
        return $checksum;
require 'openssl'
require "base64"

hash  = OpenSSL::HMAC.digest('sha256', "secretKey", "checksumString")
import hashlib
import hmac
import base64

message = bytes('checksumString', 'utf-8')
secret = bytes('secretKey', 'utf-8')

signature = base64.b64encode(hmac.new(secretKey, checksumString, digestmod=hashlib.sha256).digest())
using System.Security.Cryptography;

namespace Test
  public class MyHmac
    private string CreateToken(string checksumString, string secretKey)
      secretKey = secretKey ?? "";
      var encoding = new System.Text.ASCIIEncoding();
      byte[] keyByte = encoding.GetBytes(secretKey);
      byte[] messageBytes = encoding.GetBytes(checksumString);
      using (var hmacsha256 = new HMACSHA256(keyByte))
        byte[] hashmessage = hmacsha256.ComputeHash(messageBytes);
        return Convert.ToBase64String(hashmessage);
