Member Function Documentation

◆ Initialize() [1/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	const DL_GroupParameters_IntegerBased &	params,
		const Integer &	x
	)

inline

Initialize a private key over GF(p)

Parameters

params	the group parameters
x	the private exponent

Definition at line 651 of file gfpcrypt.h.

◆ Initialize() [2/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	const Integer &	p,
		const Integer &	g,
		const Integer &	x
	)

inline

Initialize a private key over GF(p)

Parameters

p	the modulus
g	the generator
x	the private exponent

Definition at line 658 of file gfpcrypt.h.

◆ Initialize() [3/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	const Integer &	p,
		const Integer &	q,
		const Integer &	g,
		const Integer &	x
	)

inline

Initialize a private key over GF(p)

Parameters

p	the modulus
q	the subgroup order
g	the generator
x	the private exponent

Definition at line 666 of file gfpcrypt.h.

◆ Initialize() [4/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	RandomNumberGenerator &	rng,
		const Integer &	p,
		const Integer &	g
	)

inline

Create a private key.

Parameters

rng	a RandomNumberGenerator derived class
p	the modulus
g	the generator

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 634 of file gfpcrypt.h.

◆ Initialize() [5/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	RandomNumberGenerator &	rng,
		const Integer &	p,
		const Integer &	q,
		const Integer &	g
	)

inline

Create a private key.

Parameters

rng	a RandomNumberGenerator derived class
p	the modulus
q	the subgroup order
g	the generator

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 645 of file gfpcrypt.h.

◆ Initialize() [6/6]

template<class GP >

void DL_PrivateKey_GFP< GP >::Initialize	(	RandomNumberGenerator &	rng,
		unsigned int	modulusBits
	)

inline

Create a private key.

Parameters

rng	a RandomNumberGenerator derived class
modulusBits	the size of the modulus, in bits

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.
