# NCryptEnumAlgorithms with Key storage provider (KSP)
<a name="ksp-library-apis-enum-algorithms"></a>

The `NCryptEnumAlgorithms` function retrieves the names of algorithms that the Key Storage Provider (KSP) supports.

## Parameters
<a name="ksp-library-apis-enum-algorithms-parameters"></a>

 `hProvider` [in]   
 The handle of the key storage provider for which to enumerate the algorithms. Use the [`NCryptOpenStorageProvider`](ksp-library-apis-open-provider.md) 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:

`pdwAlgCount` [out]  
The address of a DWORD that stores the number of elements in the `ppAlgList` array.

`ppAlgList` [out]  
The address of an `NCryptAlgorithmName` structure pointer that stores an array of registered algorithm names. The `pdwAlgCount` parameter indicates the number of elements in this array.

`dwFlags` [in]  
Flags to modify the function's behavior. Use zero or the following value:
