 operation used to link to the CSP-managed information.

SPI PARAMETERS    [Toc]    [Back]

       The handle that describes the add-in cryptographic service
       provider module used to perform up calls to CSSM  for  the
       memory functions managed by CSSM.  Pointer to CSSM_CONTEXT
       structure that describes the attributes with this context.

DESCRIPTION    [Toc]    [Back]

       This function initializes the staged verify data function.

       For staged operations, a combination  operation  selecting
