(CSSM_CSP_HANDLE CSPHandle,
CSSM_ALGORITHMS AlgorithmID,
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 error. |
| AlgorithmID (input) |
| | | The algorithm identification number for message
digests. |
| NewContextHandle (output) |
| | | Cryptographic context handle. |
DESCRIPTION
This function creates a digest cryptographic context, given
a handle of a CSP and an algorithm identification number. The cryptographic
context handle is returned. The cryptographic context handle can
be used to call digest cryptographic functions.
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.
