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;

Members

pszObjId

Parameters
BLOB (Cryptography) structure providing encoded algorithm specific values. In many cases, there are no parameters. This is indicated by setting the cbData member of the BLOB structure to zero.

The following table shows algorithms that have encoded parameters. For more information, see Constants for CryptEncodeObject and CryptDecodeObject.
