NAME
CSSM_CSP_CreateRandomGenContext — Create a random number generation cryptographic context (CDSA)
SYNOPSIS
# include <cssm.h>
|
|
|
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.
