TryHackMe Walkthrough – Cryptography Basics | Step-by-Step Guide

Welcome to this beginner-friendly walkthrough of the TryHackMe “Cryptography Basics” room — part of the Cyber Security 101 learning path! In this step-by-step guide, I’ll walk you through: • The importance of cryptography — what it is and why we need it (hint: think PCI DSS!) • Key terminology: plaintext, ciphertext, encryption, decryption • Historical ciphers in action — decrypting “XRPCTCRGNEI” using a Caesar cipher to get “ICANENCRYPT” • Understanding symmetric encryption (DES vs. AES) — why DES isn’t trusted anymore and the origin of AES (adopted in 2001) • Essential math for cryptography — bitwise XOR and modulo operations, with examples like `1001 ⊕ 1010 = 0011` and `118613842 % 9091 = 3565` • A walkthrough of all the room’s tasks, answers to the embedded questions, and clear explanations along the way Perfect for total beginners — no prior crypto knowledge needed! By the end of this video, you’ll be more confident with foundational encryption concepts and ready to move on to asymmetric cryptography. 🔗 TryHackMe Room: [insert link to the Cryptography Basics room on TryHackMe] 👍 If this walkthrough helps you, please like, subscribe, and hit the notification bell for more TryHackMe lessons and cyber-security tutorials!
