PJyuIchi.NET

PJyuIchi.NET is a PKCS#11 wrapper class library for the .NET Framework.

PKCS#11 or Cryptoki defines a platform-independent API to cryptographic tokens, such as Hardware Security Modules (HSM) and smart cards. Cryptoki, pronounced crypto-key and short for cryptographic token interface, follows a simple object-based approach, addressing the goals of technology independence (any kind of device) and resource sharing (multiple applications accessing multiple devices), presenting to applications a common, logical view of the device called a cryptographic token.

PJyuIchi.NET is free for non-commercial use. Download the beta version from the following location.
