Recently, I came across a technical use-case, where a system required a combination of symmetric and asymmetric encryption for communication. To be more precise, the payload was encrypted using a generated symmetric key and that key was encrypted using the public key (asymmetric encryption) of the target system. High-level Fundamentals Recalling cs fundamentals, symmetric encryption uses the same key for encryption and decryption. On the other hand, asymmetric encryption uses two different keys1....

Have you wondered what it takes to create your own programming language? Have you wondered what it takes to write an interpreter? I certainly have and recently got inspired by this blog post series. As it turns out, it is not that complicated. Only three steps are involved: Lexing - split text into words and symbols (tokens) Parsing - create a program structure (AST) Interpreting - traverse and execute the structure The full code is available on Github at https://github....
