For my first post, I wanted to list and recommend some nice resources for learning about cryptography, malware, and reverse engineering. They are a mixture of books and courses and websites.
Reverse Engineering
Personally, I started reverse engineering by cracking simple CrackMe’s and then increased the difficulty by cracking real-life applications. Then moved on to malware. These are some great resources to learn reverse engineering and cracking software:

Cryptography
I am currently in the process of learning about cryptography. To be honest, it is a quite difficult topic. Luckily, I found a really great book, which is a great introduction into cryptography. It is quite comprehensive, tightly packed with information and high-level enough to grasp the concepts of various ciphers. I highly recommend you to take your time studying this book and the topic in general:

Malware (Development)
Now to one of my, if not my favorite topic, I’ve ever discovered. Malware. I fucking love malware. From developing malware to reversing malware. It feels like black magic, capable of damaging software, to disrupting parts of nuclear reactors (Go check out Stuxnet).
I have a shit ton of resources for it. I might not find everything right now, but I keep the resources in this blog post updated. Here are some resources I could find right now:
