How to encrypt and decrypt data

Encryption

API Encryption

All of the body data will need to be encrypted using AES-256. The response also will be in encrypted AES-256

Detail:

● Encryption Method: openssl_encrypt AES-256

● body: request body

● Method: aes-256-cbc

● Ciphertext: Provided by Innov8tif

● API_key: Provided by Innov8tif

● Encryption Formula:

data = openssl_encrypt(body, method, ciphertext+API_key, OPENSSL_RAW_DATA, ciphertext)

PHP

$body = 'your_body';
$method = 'AES-256-CBC';
$ciphertext = 'your_ciphertext';
$API_key = 'your_api_key';

$key = $ciphertext . $API_key;

$encryptedText = openssl_encrypt($body, $method, $key, OPENSSL_RAW_DATA, $ciphertext);

echo base64_encode($encryptedText);
?>

JAVA

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class OpenSSLExample {
    public static void main(String[] args) throws Exception {
        String body = "your_body";
        String method = "AES/CBC/PKCS5Padding";
        String ciphertext = "your_ciphertext";
        String API_key = "your_api_key";

        SecretKeySpec keySpec = new SecretKeySpec((ciphertext + API_key).getBytes(StandardCharsets.UTF_8), "AES");
        Cipher cipher = Cipher.getInstance(method);
        cipher.init(Cipher.ENCRYPT_MODE, keySpec);

        byte[] encryptedBytes = cipher.doFinal(body.getBytes(StandardCharsets.UTF_8));
        String encryptedText = Base64.getEncoder().encodeToString(encryptedBytes);

        System.out.println(encryptedText);
    }
}

PYTHON

from Crypto.Cipher import AES
from Crypto.Util.Padding import pad
import base64

body = b'your_body'
method = 'AES/CBC/PKCS5Padding'
ciphertext = 'your_ciphertext'
API_key = 'your_api_key'

key = (ciphertext + API_key).encode('utf-8')
cipher = AES.new(key, AES.MODE_CBC)

# Padding the data to match the block size
padded_data = pad(body, AES.block_size)

encrypted_bytes = cipher.encrypt(padded_data)
encrypted_text = base64.b64encode(encrypted_bytes).decode('utf-8')

print(encrypted_text)

Decryption

PHP

<?php

$encryptedText = 'your_encrypted_text';
$method = 'AES-256-CBC';
$ciphertext = 'your_ciphertext';
$API_key = 'your_api_key';

$key = $ciphertext . $API_key;

$decryptedText = openssl_decrypt(base64_decode($encryptedText), $method, $key, OPENSSL_RAW_DATA, $ciphertext);

echo $decryptedText;
?>
