The ObjectIdPublicKeyFlags enumeration type specifies whether a public key algorithm is used for signing or for encryption. Some algorithms, such as RSA, can be used for both purposes. This enumeration is used by the InitializeFromAlgorithmName method on the IObjectId interface to narrow and disambiguate the algorithm search.
Syntax
typedef enum ObjectIdPublicKeyFlags {
XCN_CRYPT_OID_INFO_PUBKEY_ANY = 0,
XCN_CRYPT_OID_INFO_PUBKEY_SIGN_KEY_FLAG = 0x80000000,
XCN_CRYPT_OID_INFO_PUBKEY_ENCRYPT_KEY_FLAG = 0x40000000
} ;
Constants
