Nix Shells

Nix4cyber (or n4c) is a framework that uses the Nix package manager to provide reproducible cybersecurity toolkits. The project is organized into toolkits (e.g., OSINT, Web, Networking), each with a nix shell that defines its specific software environment.

This approach ensures that all dependencies are isolated and consistent, allowing users to perform security tasks with a predictable set of tools.

Usage#

To use nix4cyber, you need to have Nix installed on your system. You can then start a shell with the following command:

nix develop github:nix4cyber/n4c#<toolkit>

Alias#

Add the following in your shell config:

function n4c() {
    category=${1:-all}
    shift
    args=${*}
    nix develop "github:nix4cyber/n4c#${category}" ${args} # -c zsh # Escape the $ with ''$ in nix
    # mkdir -p /tmp/$(date +"%d%m%y") && cd /tmp/$(date +"%d%m%y") # To create a temporary directory
}

Then you can use the following command to start the shell:

n4c <category>
