PKCS #11: Cryptographic Token Interface Standard
This standard specifies an API, called Cryptoki, to devices which hold cryptographic information and perform cryptographic functions. 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.
The draft Version 2.30 of the PKCS #11 specification is now available for 30-day public review. The public review will continue through Wednesday 28-Oct-2009. Please send all comments to firstname.lastname@example.org.
