Detailed Description

template<class GP>
class DL_PrivateKey_GFP< GP >

Discrete Log (DL) private key in GF(p) groups.

Template Parameters
GPGroupParameters derived class

Definition at line 301 of file gfpcrypt.h.

Member Function Documentation

template<class GP >
void DL_PrivateKey_GFP< GP >::Initialize ( RandomNumberGenerator rng,
unsigned int  modulusBits 
)
inline

Create a private key.

Parameters
rnga RandomNumberGenerator derived class
modulusBitsthe 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.

Definition at line 312 of file gfpcrypt.h.

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

Create a private key.

Parameters
rnga RandomNumberGenerator derived class
pthe modulus
gthe 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 322 of file gfpcrypt.h.

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
rnga RandomNumberGenerator derived class
pthe modulus
qthe subgroup order
gthe 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 339 of file gfpcrypt.h.

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
