CRYPT_ENUM_OID_FUNCTION callback function

The CRYPT_ENUM_OID_FUNCTION callback function is used with the CryptEnumOIDFunction function.

Syntax

BOOL WINAPI CRYPT_ENUM_OID_FUNCTION(
  _In_       DWORD   dwEncodingType,
  _In_       LPCSTR  pszFunctionName,
  _In_       LPCSTR  pszOID,
  _In_       DWORD   cValue,
  _In_ const DWORD   *rgdwValueType,
  _In_ const LPCWSTR *rgpwszValueName,
  _In_ const BYTE    *rgpbValueData,
  _In_ const DWORD   *rgcbValueData,
  _In_       void    *pvArg
);

Parameters

dwEncodingType [in]

Specifies the encoding type to match. Setting this parameter to CRYPT_MATCH_ANY_ENCODING_TYPE matches any encoding type.

Note  If CRYPT_MATCH_ANY_ENCODING_TYPE is not specified, either a certificate or message encoding type is required.

 

If the low-order word containing the certificate encoding type is nonzero, it is used. Otherwise, the high-order word containing the message encoding type is used. If both are specified, the certificate encoding type in the low-order word is used.

Currently defined encoding types are:

• CRYPT_ASN_ENCODING
• X509_ASN_ENCODING
• PKCS_7_ASN_ENCODING
• CRYPT_MATCH_ANY_ENCODING_TYPE

pszFunctionName [in]

Name of the OID function.

pszOID [in]

A pointer to either an OID string, such as "2.5.29.1", an ASCII string, such as "file", or a numeric string, such as #2000.

cValue [in]

Count of elements in the array of value types.

rgdwValueType [in]

Array of value types. Each entry in the array will be one of the value types listed for CryptGetOIDFunctionValue under pdwValueType.

rgpwszValueName [in]

Array of null-terminated strings containing the names of the values.

rgpbValueData [in]

Array containing the values corresponding to the names in the rgpwszValueName array.

rgcbValueData [in]

Array that specifies the size, in bytes, of corresponding elements of the rgpbValueData array.

pvArg [in]

A pointer to arguments passed through to the callback function.

Return value

Returns TRUE if the function succeeds, FALSE if it fails.
