Introduction

Pretty Good Privacy (PGP) is a widely used encryption program that provides cryptographic privacy and authentication for data communication. This lab aims to familiarize students with the practical implementation of PGP, including key generation, encryption, and decryption processes. By completing this lab, students will gain hands-on experience with the fundamental concepts of asymmetric encryption, digital signatures, and secure communication protocols.

Objectives

  • Understand the basics of PGP encryption and decryption.
  • Create public and private key pairs using PGP tools.
  • Encrypt a message using a recipient's public key.
  • Decrypt a message using a private key.
  • Capture and document the process with screenshots.

Procedure

Step 1: Downloading the PGP Tool

Download and install a PGP software such as GnuPG or another recommended tool. Capture a screenshot showing the installation process and the initial launch of the application.

Step 2: Generating Key Pair

Generate a new public-private key pair in the PGP tool. Provide details such as your name and email address. Take a screenshot of the key generation process.

Step 3: Exporting Public Key

Export and save your public key to a file. Insert a screenshot showing the exported public key and the save dialog box.

Step 4: Encrypting a Message

Use your recipient’s public key to encrypt a message. Capture the encryption process with screenshots. Include the plaintext message and the encrypted output.

Step 5: Decrypting the Message

Use your private key to decrypt the message. Document the decryption process with screenshots, showing both the encrypted message and the decrypted plaintext.

Step 6: Digital Signatures (Optional)

Create a digital signature for a message and verify it. Capture screenshots of signing a message and the verification process.

Reporting

For each step, include the screenshot and a brief explanation of what the image demonstrates. Ensure clarity and detail in your documentation to provide a comprehensive view of the process.

Conclusion

This lab provides practical exposure to PGP operations, reinforcing theoretical knowledge with real-world application. Understanding how to generate keys, encrypt messages, and decrypt data forms the foundation of secure communication practices.
