Member Function Documentation

◆ Initialize() [1/4]

template<class EC >

void DL_PrivateKey_ECGDSA< EC >::Initialize	(	const DL_GroupParameters_EC< EC > &	params,
		const Integer &	x
	)

inline

Initialize an EC Private Key using {GP,x}.

Parameters

params	group parameters
x	the private exponent

This Initialize() function overload initializes a private key from existing parameters.

Definition at line 429 of file eccrypto.h.

◆ Initialize() [2/4]

template<class EC >

void DL_PrivateKey_ECGDSA< EC >::Initialize	(	const EC &	ec,
		const Element &	G,
		const Integer &	n,
		const Integer &	x
	)

inline

Initialize an EC Private Key using {EC,G,n,x}.

Parameters

ec	the elliptic curve
G	the base point
n	the order of the base point
x	the private exponent

This Initialize() function overload initializes a private key from existing parameters.

Definition at line 442 of file eccrypto.h.

◆ Initialize() [3/4]

template<class EC >

void DL_PrivateKey_ECGDSA< EC >::Initialize	(	RandomNumberGenerator &	rng,
		const DL_GroupParameters_EC< EC > &	params
	)

inline

Create an EC private key.

Parameters

rng	a RandomNumberGenerator derived class
params	the EC group parameters

This function overload of Initialize() creates a new private key because it takes a RandomNumberGenerator() as a parameter. If you have an existing keypair, then use one of the other Initialize() overloads.

Definition at line 455 of file eccrypto.h.

◆ Initialize() [4/4]

template<class EC >

void DL_PrivateKey_ECGDSA< EC >::Initialize	(	RandomNumberGenerator &	rng,
		const EC &	ec,
		const Element &	G,
		const Integer &	n
	)

inline

Create an EC private key.

Parameters

rng	a RandomNumberGenerator derived class
ec	the elliptic curve
G	the base point
n	the order of the base point

This function overload of Initialize() creates a new private key because it takes a RandomNumberGenerator() as a parameter. If you have an existing keypair, then use one of the other Initialize() overloads.

Definition at line 466 of file eccrypto.h.

◆ MakePublicKey()

template<class EC >

virtual void DL_PrivateKey_ECGDSA< EC >::MakePublicKey ( DL_PublicKey_ECGDSA< EC > & pub ) const

inlinevirtual

Definition at line 469 of file eccrypto.h.

◆ GetVoidValue()

template<class EC >

virtual bool DL_PrivateKey_ECGDSA< EC >::GetVoidValue	(	const char *	name,
		const std::type_info &	valueType,
		void *	pValue
	)		const
