Introduction

passgen is a password generation tool that allows you to create secure and customizable passwords. It generates passwords based on user-specified criteria, including password length and character types (lowercase letters, uppercase letters, digits, and special characters). You can also use passgen without any options to generate a random password with default settings.

Building

This tool is provided as source code and can be built using make. By just typing make in the terminal within the code's directory:

make

You should now have an executable named passgen. You can copy it to a location in your PATH for easy access.

Usage

To use passgen, open your terminal and execute the program with the desired options.

./passgen [OPTIONS]
