azot\n\n[![npm version](https://img.shields.io/npm/v/azot?style=flat\u0026color=black)](https://www.npmjs.com/package/azot)\n![GitHub Downloads (all assets, latest release)](https://img.shields.io/github/downloads/vitalygashkov/azot/latest/total?style=flat\u0026color=black)\n[![npm downloads](https://img.shields.io/npm/dt/azot?style=flat\u0026color=black)](https://www.npmjs.com/package/azot)\n\nAzot (Russian word for \"nitrogen\", pronounced `/azо́t/`) is a set of tools (JavaScript library, command-line utility and browser extension) for diagnosing, researching, and pentesting [DRM](https://www.urbandictionary.com/define.php?term=DRM) systems like [Widevine](https://www.widevine.com/about).\n\n\u003e Azot is still in the early stages of development, so until version 1.0 is released, performance may be unstable and major changes may be made\n\n## Features\n\n- **Minimal** dependencies\n- **Runtime agnostic** core: works in Node.js, Bun, Deno, browsers and more\n- **Logging** details from EME events in Developer Tools console of current page\n- **Encrypted Media Extensions API** compatibility via `requestMediaKeySystemAccess()` method\n- **Converting clients** between formats via CLI\n- **Manifest V3** compliant browser extension\n- **Custom client support**: WVD v2, device_client_id_blob + device_private_key, client_id.bin + private_key.pem\n- **Network-independent interception**, so it doesn't matter if the request has one-time tokens or a custom request/response body format.\n- **Remote instance** to control sessions via REST API\n\n## Installation\n\n\u003e JavaScript library and command-line tool installation requires pre-installed JavaScript runtime (e.g. Node.js).\n\n### JavaScript library\n\n```bash\nnpm install azot\n```\n\n### Command-line tool\n\n```bash\nnpm install -g azot\n```\n\n### Chrome extension\n\n**Developer Mode** needs to be enabled in `chrome://extensions/` page\n\n1. Download archive from [latest release](https://github.com/vitalygashkov/azot/releases/latest)\n2. Go to `chrome://extensions/` page\n3. Ensure Developer Mode enabled and then drag and drop downloaded zip file to this page\n\n[Read Google's guide](https://developer.chrome.com/docs/extensions/get-started/tutorial/hello-world#load-unpacked)\n\n### Firefox extension\n\n1. Download archive from [latest release](https://github.com/vitalygashkov/azot/releases/latest)\n2. Go to `about:debugging#/runtime/this-firefox` page\n3. Click `Load Temporary Add-on` button and choose downloaded zip file\n\n\u003e Temporary add-on is not persistent and will be removed after browser restart\n\n[Read Mozilla's guide](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Your_first_WebExtension#installing)\n\n## Usage\n\n### Library\n\nSee [examples](https://github.com/vitalygashkov/azot/blob/main/examples).\n\n### Command-line tool\n\nSee help: `azot --help`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvitalygashkov%2Fazot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvitalygashkov%2Fazot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvitalygashkov%2Fazot/lists"}
