Encryption & Decryption Guide

Encryption & Decryption Guide for EnKash API Integration

EnKash APIs require AES encryption with ECB mode and PKCS5 padding to secure request payloads. This guide walks you through implementing encryption and decryption in Java before sending and receiving API requests.

Encryption of API Requests

To encrypt your request data before sending it to EnKash APIs, follow these steps:

Import Required Libraries

Add the following imports in your Java code:

Implement the Encryption Function

Create a method to encrypt request data using AES-128 with ECB mode and PKCS5 padding.

Generate a SecretKeySpec for Encryption

This method ensures the secret key is hashed and trimmed to 128 bits for AES encryption.

Encrypt Data Before Sending an API Request

Use the encryption method to secure your request data before passing it to the API.

Decryption of API Responses

To decrypt the API response, implement the following

Decryption Function

Decrypt API Response

After receiving an encrypted API response, decrypt it using the following:

Do not include double quotes (" ") in input strings.
Ensure no trailing whitespaces exist in the encrypted string.
Use the same secret key for both encryption and decryption.
Always handle exceptions to avoid unexpected failures.
