Secure Password Generator

Secure Password Generator is a command-line tool for generating secure passwords. The program supports customization of password length, the inclusion of symbols or special characters, and the ability to generate multiple passwords at once. Additionally, it allows users to write the generated passwords to a file or append them to an existing file, and copy the passwords to the clipboard, providing flexible output options for different use cases.

Features

• Generate secure passwords with a specified length (default length: 20)
• Command-line switches for controlling password length, symbols or special character inclusion, and quiet mode
• Option to generate multiple passwords at once
• Supports writing generated passwords to a file or appending them to an existing file
• Supports copying generated passwords to the clipboard on Windows, Linux, and macOS

Implementation

The program is implemented in C++ and uses the C++11 random number library for generating random characters. It uses a cryptographically secure pseudo-random number generator to ensure the generated passwords are secure.

Building the Program

Prerequisites

• C++11 compatible compiler
• CMake 3.10 or higher

Building on Windows, Linux, and macOS

1. Clone the repository:

git clone https://github.com/chatgptdev/SecurePasswordGenerator.git
cd SecurePasswordGenerator

2. Create a build directory:

mkdir build && cd build

3. Run CMake to generate build files:

cmake ..

4. Build the project:

cmake --build .

The secure_password_generator binary will be created in the build directory.
