Bit4id - Universal Middleware by Bit4Id is a cross‑platform driver and cryptographic middleware package that enables operating systems and applications to work seamlessly with Bit4id smart cards, USB tokens, and readers. It exposes standard interfaces—including PKCS#11, Microsoft CSP/CAPI and CNG, and the Microsoft Smart Card Minidriver—so the same credentials can be used for digital signing, authentication, and encryption across browsers, email clients, VPNs, and document‑signing tools.
The package includes 32‑ and 64‑bit libraries and a management utility for tasks such as PIN change/unlock, token initialization, and certificate import. Designed for Windows, macOS, and Linux, it supports centralized, silent deployment for enterprise environments and interoperates with common third‑party software without custom integration. When paired with compatible certified devices, it can enable qualified electronic signatures and other trust services aligned with industry standards. Universal Middleware helps reduce compatibility issues, streamline user onboarding, and deliver a consistent, secure experience across platforms.
