️ Engineer's Password Generator

A Light-Weight, cryptographically secure password generation tool built with Zulu Java 25 and JavaFX. This application provides brute-force estimations based on RTX 4090 Hashrate performance.

Key Features

• Cryptographically Secure: Utilizes java.security.SecureRandom for non-deterministic, high-entropy character selection.
• Modern Material UI: Integrated with MaterialFX for a fluid "Material Design" aesthetic, including animated sliders and toggle buttons.
• Strength Analysis: Complexity calculation estimating the "Time to Crack" against an NVIDIA RTX 4090 (estimated at 164 Billion hashes/sec).

Technical Stack

• Language: Java 25+
• Framework: JavaFX
• UI Library: MaterialFX
• Security: CSPRNG (Secure-Package Random Number Generator)
• Architecture: MVC (Model-View-Controller) pattern

Complexity Logic

The application calculates the total entropy of the password pool and compares it against the documented performance of high-end hardware.

The Formula

The entropy is calculated by determining the bit-strength of the password based on pool size ($P$) and length ($L$):

$$Complexity = \log_2(P^L)$$

The time to crack ($T$) in hours is derived using the hash rate of a modern GPU:

$$T = \frac{2^{Complexity}}{164 \times 10^9 \times 3600}$$

Getting Started

1. Clone the repository:

   git clone [https://github.com/AnasDevO/JavaFX_Password_Generator.git](https://github.com/AnasDevO/JavaFX_Password_Generator.git)

2. Build the project: Ensure you have JavaFX compatible distro of Java 25+ installed (Zulu preferred) and run:

   ./gradlew run
