## Overview

This repository is a security cheat sheet, not an executable application. Its principal user workflow is to consult the README for security concepts and threats, then reference network defenses and cryptographic techniques. The README documents Netfilter and iptables, encryption methods and protocols, hashing, Kerberos, elliptic curves, and OpenSSL. Only the README is present in the supplied tree, so all content nodes point to it; undocumented links between topics are omitted.

Main entry points: [`README.md`](https://github.com/rihemebh/security-cheat-sheet/blob/main/README.md) (Asymmetric encryption)
