First public reviews for Version 3.1 end April 16th
OASIS and the OASIS PKCS 11 TC are pleased to announce that PKCS #11 Specification v3.1 and PKCS #11 Profiles v3.1 are now available for public review and comment. These 30-day reviews are the first public reviews for Version 3.1 of these specifications.
About the specification drafts
The Public Key Cryptography Standards (PKCS) are a group of public-key cryptography standards devised and published by RSA Security LLC, starting in the early 1990s. The OASIS PKCS 11 Technical Committee addresses the on-going enhancement and maintenance of the PKCS #11 standard.
These PKCS #11 specifications define a platform-independent API to cryptographic tokens, such as hardware security modules and smart cards. The API itself is named “Cryptoki” (from “cryptographic token interface” and pronounced as “crypto-key”).
– “PKCS #11 Specification” defines data types, functions and other basic components of the PKCS #11 Cryptoki interface for devices that may hold cryptographic information and may perform cryptographic functions. It also defines mechanisms that are anticipated for use with the current version of PKCS #11.
– “PKCS #11 Profiles” is intended for developers and architects who wish to design systems and applications that conform to the PKCS #11 Cryptoki specification as providers or consumers.
