    Constructor & Destructor Documentation

    CDHKeyPair ( void )

    IMPORT_CCDHKeyPair(void)[protected]

    Default constructor

    ~CDHKeyPair ( void )

    IMPORT_C~CDHKeyPair(void)[virtual]

    The destructor frees all resources owned by the object, prior to its destruction.

    Member Function Documentation

    ConstructL ( RInteger &, RInteger & )

    IMPORT_C voidConstructL(RInteger &aN,
    RInteger &aG
    )[protected]

    Constructor

    ParameterDescription

    aGThe DH parameter, g (the generator)

    ConstructL ( RInteger &, RInteger &, RInteger & )

    IMPORT_C voidConstructL(RInteger &aN,
    RInteger &aG,
    RInteger &ax
    )[protected]

    Constructor

    ParameterDescription
    aNThe DH parameter, n (a large prime)
    aGThe DH parameter, g (the generator)
    axThe DH value, x (a random large integer)

    NewL ( RInteger &, RInteger & )

    IMPORT_C CDHKeyPair *NewL(RInteger &aN,
    RInteger &aG
    )[static]

    Creates a new DH key pair from a random large integer, and a specified large prime and generator.

    leave
    KErrArgument If aG is out of bounds
    ParameterDescription
    aNThe DH parameter, n (a large prime)
    aGThe DH parameter, g (the generator)

    Returns: A pointer to a new CDHKeyPair object

    NewL ( RInteger &, RInteger &, RInteger & )

    IMPORT_C CDHKeyPair *NewL(RInteger &aN,
    RInteger &aG,
    RInteger &ax
    )[static]

    Creates a new DH key pair from a specified large prime, generator, and random large integer.

    leave
    KErrArgument If either aG or ax are out of bounds
    ParameterDescription
    aNThe DH parameter, n (a large prime)
    aGThe DH parameter, g (the generator)
