Features & Capabilities

The PemHeart Web Client Extension is a developer component compatible with Windows, Mac OS, and Linux systems. It allows seamless signing and encryption of electronic documents right from within your web browser. The extension works alongside a native application responsible for smartcard handling and cryptographic operations, providing a smooth interface for web applications.

Key features include support for PKCS#11 cryptographic smartcards and PFX (PKCS#12) key files stored locally. The native application automatically launches when the browser calls relevant functions, ensuring efficient document security workflows. This makes PemHeart Web Client Extension an essential tool for secure document management in web environments.
