Lesson 2— Mastering Network Defense: PGP/GPG, LAMP STACK, WORDPRESS, MFA, AND SSH DATA

A Detailed Guide for Beginners: PGP/GPG, LAMP Stack, WordPress, MFA, and SSH Data

Welcome to this in-depth walkthrough tailored for absolute beginners! Let’s delve into the essentials of PGP/GPG, LAMP Stack, WordPress, Multi-Factor Authentication (MFA), and SSH Data. By the end of this guide, you’ll have hands-on knowledge and practical experience with these technologies.

1. PGP/GPG (Pretty Good Privacy/GNU Privacy Guard)

What is PGP/GPG?

PGP and GPG are encryption tools that secure your data. They allow you to sign, encrypt, and decrypt data, ensuring confidentiality and authenticity.

Setting Up GPG:

Step 1: Server and Windows Client Setup

• For Windows: Download and install Gpg4win.
• For Linux: Install GPG directly from the terminal using sudo apt install gpg.

Step 2: Generating a PGP Key

• Open the GPG application and select ‘Generate Key’.
• Set a strong passphrase for your key.

Step 3: Sharing and Archiving Keys

• Share your public key with others for encrypted communication. Always keep your private key secure and consider making backup copies.

Practical Tasks with GPG:

Creating and Signing a Text File

• Create a text file: echo 'Hello, World!' > myfile.txt
• Sign the file: gpg --sign myfile.txt

Verifying the Signature of a File

• Use the command: gpg --verify myfile.txt.gpg

Sharing Your Public Key

• Export your public key: gpg --export -a 'Your Name' > public.key
• Share the public.key file with others.

2. LAMP Stack (Linux, Apache, MySQL, PHP)

Setting Up the LAMP Stack:
