Pass Update

Abstract

1. Introduction

pass update extends the pass utility with an update command providing an easy flow for updating passwords. It supports path, directory and wildcard update. Moreover, you can select how to update your passwords by automatically generating new passwords or manually setting your own.

pass update assumes that the first line of the password file is the password and so only ever updates the first line unless the --multiline option is specified.

By default, pass update prints the old password and waits for the user before generating a new one. This behaviour can be changed using the provided options.

2. Objective

A pass extension that provides an easy flow for updating passwords.

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