I Cracked This "SECURE VAULT" Using Pure Math | Google CTF 2025 (BEGINNER'S QUEST)

In this video, I reverse engineer a CTF binary called "SECURE VAULT" from Google CTF 2025 (BEGINNER'S QUEST) that demands a very specific 16-character password. Instead of brute-forcing billions of combinations, I use constraint analysis, XOR math, and SHA1 hashing to narrow it down to ONE password — mathematically. Perfect for beginners who want to learn reverse engineering, binary analysis, and how password verification actually works under the hood. 🔧 TOOLS USED: file, strings, objdump, nm (Linux CLI) Python 3 (hashlib, struct) Pen & paper for the math Follow me on Instagram :-   / kushgo13   Follow me on Tweeter :-   / kushgo13   #CTF #ReverseEngineering #CyberSecurity #Hacking #BinaryAnalysis #InfoSec
