ConstructL(RInteger &, RInteger &)

IMPORT_C void	ConstructL	(	RInteger &	aN,
			RInteger &	aG
		)	[protected]

Constructor

Parameters

RInteger & aN	The DH parameter, n (a large prime)
RInteger & aG	The DH parameter, g (the generator)

ConstructL(RInteger &, RInteger &, RInteger &)

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

Constructor

Parameters

RInteger & aN	The DH parameter, n (a large prime)
RInteger & aG	The DH parameter, g (the generator)
RInteger & ax	The 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

Parameters

RInteger & aN	The DH parameter, n (a large prime)
RInteger & aG	The DH parameter, g (the generator)

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

Parameters

RInteger & aN	The DH parameter, n (a large prime)
RInteger & aG	The DH parameter, g (the generator)
RInteger & ax	The DH value, x (a random large integer)

NewLC(RInteger &, RInteger &)

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

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

The returned pointer is put onto the cleanup stack.

leave: KErrArgument If aG is out of bounds

Parameters

RInteger & aN	The DH parameter, n (a large prime)
RInteger & aG	The DH parameter, g (the generator)

NewLC(RInteger &, RInteger &, RInteger &)
