SHA-2: Deep Dive

While MD5 and SHA-1 have fallen, SHA-2 stands strong. Published in 2001, the SHA-2 family has weathered over two decades of cryptanalysis and remains the workhorse of modern cryptography. This post explores every member of the SHA-2 family, how they work, and when to use each one. The SHA-2 Family

MD4: From Hero to Zero

Before MD5, there was MD4. Designed for speed above all else, MD4 became the foundation for an entire generation of hash functions—and a cautionary tale about prioritizing performance over security. Today, MD4 is so thoroughly broken that collisions can be computed by hand. This post traces MD4's

SHA-1: From Hero to Zero

For two decades, SHA-1 was the backbone of internet security—protecting SSL certificates, signing software, and verifying Git commits. Then in 2017, Google shattered it. Literally. This post traces SHA-1's journey from government-approved standard to cryptographic casualty, culminating in the SHAttered attack that proved its collision resistance was

MD5: From Hero to Zero

In 1991, MD5 was the gold standard of cryptographic hash functions. Today, it's a cautionary tale in cryptographic history. This post traces MD5's journey from trusted workhorse to deprecated relic, and the attacks that brought it down. What is MD5? MD5 (Message-Digest Algorithm 5) is a

The Evolution of Wi-Fi Security: From WEP to WPA3

Wi-Fi security has undergone dramatic changes since the late 1990s. What started as a fundamentally flawed encryption scheme has evolved into robust, cryptographically sound protocols. Understanding this evolution helps you appreciate why certain practices matter and why you should never connect to a WEP network. This guide walks through each

Hashcat on Apple Silicon: GPU-Accelerated Password Cracking

Hashcat on Apple Silicon: GPU-Accelerated Password Cracking

Apple Silicon Macs (M1, M2, M3, M4) aren't just for creative work and AI inference—they're surprisingly capable password-cracking machines. With hashcat's native Metal backend, you can leverage those GPU cores for high-speed hash cracking right from your MacBook. Legal Disclaimer: Only use hashcat

Cracking WPA/WPA2 with Aircrack-ng on Fedora

Cracking WPA/WPA2 with Aircrack-ng on Fedora

This guide covers testing WPA/WPA2 network security using the Aircrack-ng suite on Fedora Linux. We'll capture the four-way handshake and perform dictionary attacks to recover the pre-shared key. Legal Disclaimer: Only perform these techniques on networks you own or have explicit written permission to test. Unauthorized access
