Version 2.1, Draft 1


This draft represents the next revision of PKCS #11 standard. It includes the following enhancements over version 2.01:

  • formatting changes to match latest revisions of other PKCS documents
  • behavioral clarifications
  • new mechanism types
  • object enhancements
  • new objects types to support hardware feature expansion
  • method for applying a secondary authentication PIN to private key objects

The following is a detailed list of each set of edits to the version 2.01 document included in the proposed draft.

  • X.509 Attribute certificates
  • Data object attribute addition (add OID attribute)
  • Addition of RIPE-MD mechanisms
  • RFC2279 (UTF8) strings for internationalization
  • Clarification of multi-application access behavior (taken from mailing list discussion)
  • Clarification of mapping between PKCS #11 and X.509 key usage (adapted from PKCS #15)
  • Clarification of whether or not C_Encrypt can be used to terminate a multi-part operation to make sure the intended behavior is acurately reflected.
  • Addition of error codes to function descriptions
  • Clarification of C_InitToken behavior with respect to the SO PIN (taken from the percieved majority preference on the mailing list)
  • Multiple PIN handling.
  • Clarification of required lifetime of the CK_C_INITIALIZE_ARGS structure and C_FindObjectsInit templates in applications
  • Hardware feature objects to represent items such as real-time clocks, monotonic counters, etc.
