NAME

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

SYNOPSIS

# include <cdsa/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 (libcssm.so)

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.
