A Few Reading Tips
Don't try to read everything at once. Cryptography books are dense. It's better to really understand one book than to skim through five.
Keep a notebook. Seriously. The concepts build on each other, and you'll want to refer back to earlier ideas.
Find a study buddy. Cryptography is hard, and it's easier when you have someone to discuss concepts with.
Practice as you go. Reading about cryptography is great, but implementing it (safely, in a learning environment) is how you really understand it.
Remember: The best cryptography book is the one you'll actually read. Start with something that matches your current level and interests, then work your way up. The field is constantly evolving, so think of this as the beginning of a lifelong learning journey, not a checklist to complete.
