CRYPT_ALGORITHM_IDENTIFIER

  • Article

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 CRYPT_OBJID_BLOB are encoded.

typedef struct _CRYPT_ALGORITHM_IDENTIFIER {LPSTRpszObjId;CRYPT_OBJID_BLOBParameters;} CRYPT_ALGORITHM_IDENTIFIER, *PCRYPT_ALGORITHM_IDENTIFIER;
