CRYPT_PROVIDER_DATA structure

[The CRYPT_PROVIDER_DATA structure is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

The CRYPT_PROVIDER_DATA structure is used to pass data between WinVerifyTrust and trust providers.
