 NAME

   CSSM_CSP_CreateRandomGenContext - Create a random number generation
                                     cryptographic context (CDSA)

 SYNOPSIS

   # include <cssm.h>

        CSSM_RETURN CSSMAPI CSSM_CSP_CreateRandomGenContext
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_ALGORITHMS AlgorithmID,
        const CSSM_CRYPTO_DATA *Seed,
        uint32 Length,
        CSSM_CC_HANDLE *NewContextHandle)

 LIBRARY

   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 PARAMETERS

   CSPHandle (input)
           The handle that describes the add-in cryptographic service
           provider module used to perform this function. If a NULL
           handle is specified, CSSM returns AN error.

   AlgorithmID (input)
           The algorithm identification number for random number
           generation.

   Seed (input/optional)
           A seed used to generate THE random number. The caller can
           either pass a seed and seed length in bytes or pass a
           callback function.  If NULL is passed, the cryptographic
           service provider will use its default seed-handling mechanism.

   Length (input)
           The length of the random number to be generated.

   NewContextHandle (output)
           Cryptographic context handle.

 DESCRIPTION

   This function creates a random number generation cryptographic
   context, given a handle of a CSP, an algorithm identification
   number, a seed, and the length of the random number in bytes.
   The cryptographic context handle is returned and can be used for
   the random number generation function.

 RETURN VALUE

   A CSSM_RETURN value indicating success or specifying a particular
   error condition. The value CSSM_OK indicates success. All other values
   represent an error condition.
