Elliptic Curve Cryptography (ECC) is a powerful cryptographic technique that offers smaller key sizes while providing strong security. In Java, you can implement ECC encryption and decryption using libraries like Bouncy Castle, which provides support for ECC algorithms. Below, we'll walk through a basic example of how to use ECC for encryption and decryption in Java.

Generating ECC Key Pair

First, you need to generate an ECC key pair, which consists of a public key and a private key. Here's how you can generate an ECC key pair using the Bouncy Castle library:

Encryption and Decryption

Once you have the key pair generated, you can use the public key for encryption and the private key for decryption. Here's how you can perform encryption and decryption using ECC:

In this example, we use the Bouncy Castle provider and the ECIES (Elliptic Curve Integrated Encryption Scheme) cipher for encryption and decryption. Make sure to replace /* Your public key bytes */ and /* Your private key bytes */ with the actual bytes of your public and private keys obtained during the key pair generation process.

With this basic setup, you can now encrypt and decrypt data using Elliptic Curve Cryptography in your Java applications.
