Member Function Documentation

Initialize() [1/4]

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 220 of file eccrypto.h.

Initialize() [2/4]

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 229 of file eccrypto.h.

Initialize() [3/4]

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 238 of file eccrypto.h.

Initialize() [4/4]

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.
