🔐 Password Analyzer CLI

A command-line tool written in Rust that allows you to analyze password security, generate secure passwords, and detect if a password is common (based on wordlists).

🚀 Features

• Checks the strength of given passwords (length, special characters, etc.).
• Detects passwords that appear in common password files (wordlist.txt).
• Generates secure passwords with the most important criteria.
• User-friendly command-line interface using clap.
• Output with colors and symbols for clear visualization (requires ANSI support).

📦 Installation

1. Clone the repository:

git clone https://github.com/RicardoUMC/Password-Analyzer-Cli.git
cd Password-Analyzer-Cli

2. Make sure you have Rust installed.

3. Build the project:

cargo build --release

🧪 Usage

Analyze a password

cargo run -- MySecureP@ssw0rd!

Generate a secure password

cargo run -- -g

or using the following form:

cargo run -- --generate

Analyze passwords from a file

Suppose you have a list in wordlist.txt and want to check if the password is included:

cargo run -- -c wordlist.txt "123456"

or using the long form of the option:

cargo run -- -common wordlist.txt "123456"

📁 Project Structure

• src/main.rs – Main entry point of the program.
• src/cli/ – Module responsible for handling the command-line interface and argument processing.
• src/common/ – Module for loading common passwords (wordlist.txt).
• src/password/ – Module containing the core logic for password analysis and generation.
• src/utils/ – Module with various auxiliary functions such as screen prints.
• wordlist.txt – Optional wordlist of common passwords, upload your own file.

🧱 Technologies Used

• Rust
• clap – CLI parsing
• regex – Pattern validation
• colored – Terminal colors

✅ Output Examples

Received password: MySecureP@ssw0rd!
