In today's digital age, securing sensitive information is paramount. Encryption plays a crucial role in safeguarding data from unauthorized access. When it comes to image files, ensuring their confidentiality is equally important. In this guide, we'll explore how to encrypt and decrypt image files using the Advanced Encryption Standard (AES) algorithm in Java.

AES is a symmetric encryption algorithm widely used for securing data due to its reliability and efficiency. With AES, we can encrypt and decrypt data using a shared secret key. Let's delve into the implementation:

In this Java source code:

The ImageEncryption class contains methods for encrypting and decrypting images using AES.

We define constants for the AES algorithm and key size.

encryptImage() and decryptImage() methods take input image paths, output image paths, and a secret key. They read the image bytes, perform encryption or decryption using AES, and write the result to the specified output path.

generateAESKey() method generates a random AES secret key.

In the main() method, we specify paths for input, encrypted, and decrypted images. We generate a secret key, encrypt the input image, and then decrypt the encrypted image.

By following this Java source code, you can effectively encrypt and decrypt image files using AES, ensuring the confidentiality of your sensitive visual data.
