Pwd Sh

Abstract

1. Introduction

pwd.sh is a Bash script to manage text secrets, such as passwords, using GnuPG.

Each secret is saved to a randomly-named file in a directory. An encrypted index maps usernames to secrets contained in files. Both the index and files can be decrypted directly with GnuPG - without pwd.sh.

2. Objective

Manage secrets with Bash and GnuPG symmetric encryption

This project demonstrates how Shell can be applied to a real-world Cybersecurity & Ethical Hacking problem.
