pwdgen

This is a simple, lightweight password generator designed for Linux-based operating systems. While it lacks rich features, it meets my personal needs. Written in C for fun, this tool is uploaded here to ensure it is not lost. The only dependencies are getopt.h and the ability to read from /dev/urandom.

As a command-line tool, it allows you to generate random passwords with customizable options. By default, the generator includes a mix of lowercase letters, uppercase letters, digits, and special symbols. You can specify both the length of the passwords and the quantity you wish to generate.

Building

To build the Password Generator, simply run the following command in the project directory:

$ make clean release

The compiled binary will be located in the build directory.

Usage

pwdgen [OPTIONS] [PASSWORD_LENGTH] [QUANTITY]

Parameters

• PASSWORD_LENGTH: The length of each generated password. The default value is 10.
• QUANTITY: The number of passwords to generate. The default value is 1.

Options

• -l, --lowers: Include lowercase characters in the generated passwords.
• -u, --uppers: Include uppercase characters in the generated passwords.
• -d, --digits: Include digits in the generated passwords.
• -s, --symbols: Include special symbols in the generated passwords.
• -h, --help: Print help message and exit.

Examples

1. Generate a single password of default length (10 characters):

   $ pwdgen

2. Generate 5 passwords of length 12, including only lowercase letters:
