However, using a third-party website means trusting that sensitive material is handled correctly. **Crypto Key Tools** is designed for users and organizations that prefer to keep cryptographic material entirely within their own infrastructure. Features -------- [](#features) - Generate cryptographic key pairs. - Convert keys between multiple formats. - Inspect keys, certificates and related cryptographic data. - Browser-based interface. - Agnostic Routing: Consistent behavior across LAMP (Apache), IIS, and PHP's built-in server. - Easy deployment with Composer. Installation ------------ [](#installation) ### Recommended [](#recommended) Install the latest version directly with Composer: ``` composer create-project alphp/crypto-key-tools ``` The project will be installed in a new `crypto-key-tools` directory, ready to be served by your web server. ### From source [](#from-source) ``` git clone https://github.com/alphp/crypto-key-tools.git cd crypto-key-tools composer install ``` Local Development ----------------- [](#local-development) For quick testing or development, you can use PHP's built-in web server. Since the project follows a Front Controller pattern where the entry point is located in the `wwwroot` directory, you must point the document root to that folder: ``` # From the project root directory php -S localhost:8000 -t wwwroot ``` Why this works: --------------- [](#why-this-works) - **Agnostic Routing**: The system automatically calculates the `REQUEST_BASE`, ensuring that all internal links and the MiniRouter work correctly without manual configuration. - **Security by Design**: By serving only the `wwwroot` folder, sensitive files like `bootstrap.php`, `constants.php`, and the `templates` directory remain outside the web-accessible path. Usage ----- [](#usage) 1. Deploy the project to your web server (or run it locally). 2. Open the application in your browser. 3. Select the desired cryptographic operation. 4. Generate, inspect or convert your keys. Security -------- [](#security) This project is intended to be run on systems that you control. - The system protects against direct access to sensitive files (`.env`, `.git`, `.config`) by routing them to the Front Controller for a controlled 404 state. - Use HTTPS whenever possible and restrict access to trusted users.

See the `LICENSE` file for details. ### Health Score 40 — FairBetter than 86% of packages Maintenance100 Actively maintained with recent releases Popularity7 Limited adoption so far Community6 Small or concentrated contributor base Maturity39 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
