Heading Toward The End Of Season 3.1

CyberGuardians Season 3.1 Finale: How Devices Connect to the Internet

In this CyberGuardians Season 3.1 finale, we break down what happens when a device connects to the internet and a user types google.com into a browser. Using Kali Linux, Firefox, and Wireshark, we walk through DNS, TCP, TLS, HTTPS, UDP, QUIC, NAT, and the basic steps behind normal web communication. Cybersecurity starts with understanding the basics before chasing every new attack. Stay safe. Stay secure.

Symmetric vs Asymmetric Encryption Algorithms

In this episode of CyberGuardians, Marcellus hands the mic to Nequarius to break down the difference between symmetric and asymmetric encryption. Learn how encryption protects data, how algorithms like AES, RSA, Diffie-Hellman, ECC, and ChaCha20 work, and why modern cybersecurity depends on using the right encryption methods the right way.

What GPG Files Do in Linux

In this CyberGuardians episode, we explain what a GPG file is in Linux and how it can protect files through encryption. This demo covers basic encrypt and decrypt commands, why .gpg files are protected, and how a passphrase is used to unlock them. Stay safe and stay secure. Music Credit: -2020 Dyalla

Checking File Integrity with Hashes

In this episode of CyberGuardians, I break down the differences between MD5 and SHA-256, including what they are, how they work, a brief history behind both hashing algorithms, and why SHA-256 is considered the stronger and more trusted option today. I also go over the advantages and disadvantages of each one, explain why hashes matter when verifying downloaded files, and walk through how to check a file’s hash in Kali Linux using simple terminal commands. To wrap it up, I demonstrate how to compare the hash generated on your system with the official checksum provided on a website so you can better verify file integrity before trusting what you download. If you’ve ever wanted a simple explanation of hashes and a practical example of how to use them, this episode is for you. Stay safe and stay secure. If you want a slightly sharper version, use this: In this episode of CyberGuardians, I cover the key differences between MD5 and SHA-256, including their history, strengths, weaknesses, and why SHA-256 has become the better standard for verifying file integrity. I also walk through a practical Kali Linux demonstration showing how to generate a file hash in the terminal and compare it to the official checksum from a website. This is a simple but important step that can help confirm whether a downloaded file is authentic and unchanged. This episode is great for anyone who wants a better understanding of hashing and how it applies to real-world cybersecurity habits. Stay safe and stay secure. Music Credit: -2020 Dyalla
