Interfaces for Custom Encryption in Java

Create a Java program to demonstrate the use of an interface for custom encryption

The Encryptor interface defines a single method encrypt(String data) for encrypting data.
In the main method of the Main class, an instance of the Encryptor interface is created using a lambda expression that performs Base64 encoding.
The original data string is encrypted using the encrypt method of the Encryptor interface.
The original and encrypted data are printed to the console.

Source Code

import java.util.Base64;
 
interface Encryptor
{
	String encrypt(String data);
}
 
public class Main
{
	public static void main(String[] args)
	{
		Encryptor encryptor = data -> Base64.getEncoder().encodeToString(data.getBytes());
 
		String originalData = "Hello World! 123";
		String encryptedData = encryptor.encrypt(originalData);
 
		System.out.println("Original Data : " + originalData);
		System.out.println("Encrypted Data : " + encryptedData);
	}
}

Output

Original Data : Hello World! 123
Encrypted Data : SGVsbG8gV29ybGQhIDEyMw==
