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.


typedef struct _CRYPT_ALGORITHM_IDENTIFIER {
  LPSTR pszObjId;
  CRYPT_OBJID_BLOB Parameters;
} CRYPT_ALGORITHM_IDENTIFIER, *PCRYPT_ALGORITHM_IDENTIFIER;

pszObjId

Object identifier (OID) of an algorithm. The following table shows possible values for this member.
