However, this parameter is specific to the provider being used and may be any value that makes sense to the provider. The default for Microsoft Base Cryptographic Provider is AT_SIGNATURE. For information on the other Microsoft Cryptographic Service Providers, see Microsoft Cryptographic Service Providers in the CryptoAPI 2.0 documentation.
