The **xmldsigjs** monorepo provides a pure TypeScript/JavaScript implementation of XML security standards—including XML Digital Signature (XMLDSIG) and the XAdES profile—built on the Web Crypto API so it runs in modern browsers, Node.js, and even hardware security modules. It consists of three packages: `xml-core` for generic XML handling and schema validation, `xmldsigjs` for creating and verifying XML signatures, and `xadesjs` for advanced electronic signature formats. The libraries target developers who need to generate, validate, or process signed XML documents in web or server‑side JavaScript environments.
