Bit4id - CSP PKCS11 Oberthur 1.3

Bit4id - CSP PKCS11 Oberthur is a middleware and driver package that installs both a Microsoft Cryptographic Service Provider (CSP) and a PKCS#11 library to enable Oberthur smart cards and USB tokens to work with security-enabled applications. It exposes the keys and certificates stored on the card through standard interfaces, allowing digital signatures, authentication, and encryption to be performed directly on the secure hardware.

Key capabilities:

• Windows integration via CSP for CryptoAPI/CNG-aware applications (e.g., document signing, secure email, client TLS/VPN).
• PKCS#11 module for applications that support the standard interface (e.g., compatible browsers, PDF signing tools, and cryptographic utilities).
• On-card key generation and use, PIN management, and certificate access through the token.
• Designed for 32/64-bit environments and suitable for enterprise deployment.

Typical use cases:

• Digital document signing and timestamping.
• Two-factor authentication with smart cards.
• S/MIME email and certificate-based network access.

Note: This description is based on the product name and common functionality of CSP/PKCS#11 middleware for Oberthur tokens; specific features may vary by release.
