pivy

The application provides a macOS‑based client for interacting with Personal Identity Verification (PIV) smart cards. It enables users to communicate with PIV cards, perform standard operations such as reading certificates, signing data, and managing authentication credentials directly from a desktop environment. The software is designed to work with the native macOS security framework, allowing seamless integration with system keychains and authentication services.

Target users include individuals and organizations that require secure access control, government employees, and anyone employing PIV cards for multi‑factor authentication or digital signing workflows. By offering a graphical interface tailored to macOS, the client simplifies tasks that would otherwise require command‑line tools or specialized hardware utilities.

The project is marked as stable and focuses on core macOS compatibility, ensuring reliable operation on supported versions of the operating system. It does not claim cross‑platform support, and its feature set is limited to PIV card management and related cryptographic functions.
