Golang and Cryptography

I teach mainly using Python, as it’s a great language to learn principles. But I develop most of my current code in Rust and Golang, as I often need to access specialised cryptography, and which needs to run fast and securely. The thing I love about cryptography is that it forces me to learn Python, Golang, Java, C#, Node.js, and Rust, and never settle for just one of them.

So, for my 1,300th blog post, let’s have a look at some basics involved in cryptography using Golang [slides]. If you know some cryptography, hopefully you will learn a bit of Golang, and vice-versa. Here’s a presentation:

Formats

The most important representations for data in encryption are: hexadecimal and Base-64. For this, we can convert from a plaintext format into a binary form, and then use hexademical and Base-64 to represent these values:
