Zig Type System

Zig aims to be a simple language. It is not easy to define what simple exactly means, but zig is also a low-level programming language that aims for c-compatibility. To reach this goal, it needs good semantics in its type system so that developers have a complete toolbox to manipulate data.

So types in zig are composable, but this can become rapidly overwhelming. See those examples. Are you able to understand them at a glance, as soon as you read them?

*const ?u8
?*const u8
*const [2]u8

See the official Differentiable Programming Manifesto instead.

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from
