NCryptEnumAlgorithms with Key storage provider (KSP)
The NCryptEnumAlgorithms function retrieves the names of algorithms that the Key Storage Provider (KSP)
supports.
Parameters
-
hProvider[in] -
The handle of the key storage provider for which to enumerate the algorithms. Use the NCryptOpenStorageProvider function to get this handle.
-
dwAlgOperations[in] -
A set of values that specify which algorithm classes to enumerate. You can use zero to enumerate all algorithms, or combine one or more of these values:
Value Meaning NCRYPT_ASYMMETRIC_ENCRYPTION_OPERATION
0x00000004
List the asymmetric encryption algorithms.
NCRYPT_SIGNATURE_OPERATION
0x00000010
List the digital signature algorithms.
pdwAlgCount[out]-
The address of a DWORD that stores the number of elements in the
ppAlgListarray. ppAlgList[out]-
The address of an
NCryptAlgorithmNamestructure pointer that stores an array of registered algorithm names. ThepdwAlgCountparameter indicates the number of elements in this array. dwFlags[in]-
Flags to modify the function's behavior. Use zero or the following value:
Value Meaning NCRYPT_SILENT_FLAG
This flag has no effect.
Return Value
The function returns a status code to indicate success or failure.
Common return codes include:
| Return code | Description |
