After decoding Base64, we now face our first real cipher in Bandit Level 11 to 12. The password isn’t encoded for data transport; it’s been deliberately obfuscated using a simple character-shifting algorithm.

This level introduces the Caesar cipher, one of the oldest and most well-known forms of encryption. We’ll learn how to crack it with tr, a command-line utility for translating characters. 📜

The Challenge: Level 11 Goal

The level’s objective is described as follows:
