When I taught myself cryptography, I felt like an idiot for months. Either I was too stupid to get it, or the subject was made complex to such a degree that only a PhD in abstract math could get it. After a while I finally "got it", to the point where I now feel I’m a fully autodidact Cypherpunk. Hence, I feel obliged to not only teaching it to you, but also provide tools that are simple to use, such that you can get started with it yourself in some few seconds. Below is a video you can watch, and I guarantee you that you’ll understand mostly everything you’ll ever need to understand in this subject, in order to become a complete "Cypherpunk".
Creating an RSA key with Magic is as simple as follows. However, you might want to watch the above video first, and also download Magic in order to follow the rest of the code examples.
