enumProviders

The enumProviders method enumerates all providers available on the computer for the specified ProviderType property. If that property has not been changed, then it has a default value of one, as set in the registry, meaning PROV_RSA_FULL for the default Microsoft Base Cryptographic Provider, is used to do the enumeration.

[VB] BSTR enumProviders (
  DWORD dwIndex
  DWORD dwFlags
);
 
[C++] HRESULT enumProviders (
  DWORD dwIndex         // in
  DWORD dwFlags         // in
  BSTR* pbstrProvName   // in
);
 

Parameters

[VB][C++] dwIndex

Specifying zero for dwIndex gets the first provider. Increment dwIndex for successive providers. When there are no more providers, ERROR_NO_MORE_ITEMS is returned for [C++], and it is thrown for [VB].

VB][C++] dwFlags

These flags are passed through to CryptEnumProviders. See it for details.

[C++] pbstrProvName

See "Return Value."

Return Values

Returns a BSTR containing the enumerated provider. When there are no more providers, the error ERROR_NO_MORE_ITEMS is returned.
