PGP Encryption and Decryption in Java 🔒

This repository provides a tutorial and example code for implementing PGP (Pretty Good Privacy) encryption and decryption in Java using the Bouncy Castle library. 📚

Introduction

PGP is an asymmetric encryption algorithm that uses public-key cryptography to secure data communication. It involves generating a pair of keys: a public key for encryption and a private key for decryption.🌟

Prerequisites

Before getting started, make sure you have the following prerequisites:

• Java Development Kit (JDK) installed on your system 📥
• Bouncy Castle library added to your project dependencies 📦

Getting Started

To get started with PGP encryption and decryption in Java, follow these steps:

• Clone this repository to your local machine using the following command:

git clone https://github.com/iridhicode/pgp-encryption-decryption

• Open the project in your favorite Java IDE. 💻
• Make sure you have the Bouncy Castle library added to your project dependencies. You can download it from the Bouncy Castle website or add it using a build tool like Maven or Gradle. 📚
• Generate a pair of public and private keys for the sender and receiver. You can use the ssh-keygen command-line tool or any other PGP key generation tool. 🔑

Usage

To use the PGP encryption and decryption functionality, follow these steps:

• Update the main method in the PGPReader class with the appropriate file paths for your input file, private key, public keys, and email addresses. 📝
• Run the main method to perform encryption and decryption. 🚀
• The encrypted file will be generated, and the decrypted file will be output to the console or saved to a file, depending on your implementation. 📤
