ObjectIdPublicKeyFlags enumeration (certenroll.h)

  • Article

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

 
XCN_CRYPT_OID_INFO_PUBKEY_ANY
Value: 0
The algorithm can be used for signing or encryption.
XCN_CRYPT_OID_INFO_PUBKEY_SIGN_KEY_FLAG
Value: 0x80000000
The algorithm is used for signing.
XCN_CRYPT_OID_INFO_PUBKEY_ENCRYPT_KEY_FLAG
Value: 0x40000000
The algorithm is used for encryption.
