Replicate python code in nim

Thanks, I appreciate your response. I'll definitely go with libsodium for the time being. I'll also keep testing libp2p and improve my understanding on cryptography. Thanks again.

Algebraic data types and structural pattern matching RFC

The types of the variants are not required to be unique. While I somewhat agree from a type theory perspective (well, actually, I'd prefer this to be called `enum` and objects to be called `struct`), I think `union` is a much more approachable keyword that conveys what the type is doing better.

Implementing elliptic curve from scratch with no background in cryptography engineering is a tall order. For production (and not as a learning experience), it's probably easier to debug why libp2p implementation gives you a different key everytime. It has been audited and is straight from a ref

Are the types of the variants required to be unique? If not, it should be called `sum` rather than `union`.

NIM code compile to executable does not run on other systems.

The first things that come to mind are OpenSSL (because Discord APIs use SSL), and PCRE (I'm not 100% sure, but I think dimscord uses re). Try for example starting your app from the windows cmd, you might actually see the problem then. You can find those DLLs in the same folder with the Nim ins

Every OS has an executable file format of its own. An executable compiled for Windows cannot be used on macOS. Similarly, an executable compiled for macOS cannot be used on Linux. In addition, every executable is compiled for a specific CPU architecture. One cannot run a x86 executable on a mach

Nim does actually support semicolons if you need to have multiple statements on the same line, or if you're just copy pasting C code. It's not a good style, but it is there.
