CRYPT_ALGORITHM_IDENTIFIER
A version of this page is also available for
4/8/2010
This structure specifies an algorithm. The structure includes the object identifier (OID) of the algorithm and any needed parameters for that algorithm. The parameters contained in its CRYPTOAPI_BLOB (CRYPT_OBJID_BLOB) are encoded.
Syntax
typedef struct _CRYPT_ALGORITHM_IDENTIFIER {
LPSTR pszObjId;
CRYPT_OBJID_BLOB Parameters;
} CRYPT_ALGORITHM_IDENTIFIER, *PCRYPT_ALGORITHM_IDENTIFIER;
