Environment Setup
Install your development tools and verify they work correctly. We provide specific configuration files for Python environments. Takes about an hour if everything goes smoothly—maybe two if you hit permission issues.
Getting Ready to Learn Encryption
Before jumping into encryption programming, let's talk about what you actually need. Not fancy equipment or expensive software—just some realistic expectations and a bit of foundational knowledge.
Most people think encryption is this mysterious, untouchable field. And yeah, it can get complicated. But starting out? That's surprisingly straightforward if you know where to begin.
What You'll Need to Know
These aren't prerequisites in the traditional sense. Think of them more as areas where having some familiarity will make your life easier when you start writing encryption code.
Basic Programming
You should be comfortable with at least one language. Python works great for beginners because the syntax doesn't get in your way. But if you prefer JavaScript or Java, that's fine too.
Binary Thinking
Encryption happens at the bit level. Understanding how data converts to binary and why that matters will save you hours of confusion later. We're not talking about memorizing conversion tables—just grasping the concept.
Problem Solving
Honestly, this matters more than technical skills sometimes. Encryption bugs can be subtle. You'll need patience and a methodical approach to tracking down why your encrypted output looks wrong.
Our Teaching Approach
We don't throw you into advanced cryptographic algorithms on day one. That's a recipe for frustration. Instead, you'll start with simple substitution ciphers—the kind that seem almost too basic at first.
But here's the thing: those simple ciphers teach you the fundamental patterns that show up in modern encryption. Understanding Caesar shifts helps you grasp block cipher modes later. It's all connected.
By September 2025, our autumn program will guide you through increasingly complex implementations. Each project builds on what you learned before. No sudden jumps that leave you lost.

Your First Week Roadmap
Once you start the program, here's what your initial learning path looks like. We keep it focused so you're not overwhelmed.

Understanding Data Representation
Before encrypting anything, you need to see how text becomes bytes and bytes become encrypted data. We'll work through examples using different data types so you understand what's actually happening under the hood.
3
Your First Cipher
Write a working XOR cipher from scratch. It's simple but surprisingly useful for learning. You'll see firsthand why key management matters and what happens when you reuse encryption keys.
4
Breaking Your Own Code
Now we reverse the process. You'll learn basic cryptanalysis by finding weaknesses in your own implementation. Sounds backwards, but it teaches you what to avoid when building production systems.
Are You Ready to Start?
Check these items off mentally. If most apply to you, then our autumn 2025 program starting in September will be a good fit. If you're missing several, consider spending a month or two building up those areas first.
- You can write functions and use loops without constantly checking documentation
- You understand what happens when you read a file into memory
- You're familiar with debugging using print statements or a proper debugger
- You know what a byte array is and why it differs from a string
- You're comfortable reading technical documentation, even if it's dense
- You can commit 8-12 hours per week for focused study and practice
- You're okay with making mistakes and debugging your own code first
- You have genuine interest in security and how systems protect data
