Introduction to DRM Development (1) Symmetric Key Cryptography, Asymmetric Key Cryptography and Hybrid Cryptosystem

Category: Web, Security

I became interested in DRM (license activation) implementation while developing software, but the development was extremely difficult.
The most important reason for this was the lack of Japanese resources.
In this series, I will explain the development (mainly logic) of DRM as much as possible.
The first article will explain asymmetric cryptography, symmetric key cryptography, and hybrid cryptosystem.
