Member Function Documentation

template<class EC >

void DL_PrivateKey_EC< EC >::BERDecodePrivateKey	(	BufferedTransformation &	bt,
		bool	parametersPresent,
		size_t	size
	)

virtual

decode privateKey part of privateKeyInfo, without the OCTET STRING header

Implements PKCS8PrivateKey.

Definition at line 669 of file eccrypto.cpp.

Here is the call graph for this function:

template<class EC >

void DL_PrivateKey_EC< EC >::DEREncodePrivateKey ( BufferedTransformation & bt ) const

virtual

encode privateKey part of privateKeyInfo, without the OCTET STRING header

Implements PKCS8PrivateKey.

Definition at line 708 of file eccrypto.cpp.

template<class EC>

void DL_PrivateKey_EC< 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 219 of file eccrypto.h.

Here is the call graph for this function:

template<class EC>

void DL_PrivateKey_EC< 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 228 of file eccrypto.h.

Here is the call graph for this function:

template<class EC>

void DL_PrivateKey_EC< 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 237 of file eccrypto.h.

template<class EC>

void DL_PrivateKey_EC< 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.
