... are hopefully only present in CTF challenges. This repository contains a blog post about my experience solving the NSA backdoor challenge of this year's picoCTF. The post is wrapped into a Pluto notebook. Pluto notebooks are a free and open source notebook programming environment written in, and for, the Julia programming language.
If you want to read the non-interactive version of this post, simply open nsa_backdoor.html in your browser.
To view the interactive version, download the Julia binary and add it to your PATH. Then, run the julia command, press ] to enter the package manager, enter add Pluto, and finally ^C to get back to the Julia repl. Finally, open nsa_backdoor.jl by running
julia> import Pluto
julia> Pluto.run()
and navigating to wherever you git cloned this repo to.
