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.
