Member Function Documentation

template<class GROUP_PARAMETERS , class COFACTOR_OPTION = typename GROUP_PARAMETERS::DefaultCofactorOption>
void DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >::GeneratePublicKey ( RandomNumberGenerator rng,
const byte *  privateKey,
byte *  publicKey 
) const [inline, virtual]

generate public key

size of publicKey == PublicKeyLength()

Reimplemented from DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >.

Definition at line 58 of file dh.h.

void DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >::GeneratePrivateKey ( RandomNumberGenerator rng,
byte *  privateKey 
) const [inline, virtual, inherited]

generate private key

size of privateKey == PrivateKeyLength()

Implements SimpleKeyAgreementDomain.

Definition at line 1386 of file pubkey.h.

References Integer::Encode(), and Integer::One().

bool DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >::Agree ( byte *  agreedValue,
const byte *  privateKey,
const byte *  otherPublicKey,
bool  validateOtherPublicKey = true 
) const [inline, virtual, inherited]

derive agreed value from your private key and couterparty's public key, return false in case of failure

If you have previously validated the public key, use validateOtherPublicKey=false to save time.
size of agreedValue == AgreedValueLength()
length of privateKey == PrivateKeyLength()
length of otherPublicKey == PublicKeyLength()

Implements SimpleKeyAgreementDomain.

Definition at line 1400 of file pubkey.h.

void SimpleKeyAgreementDomain::GenerateKeyPair ( RandomNumberGenerator rng,
byte *  privateKey,
byte *  publicKey 
) const [virtual, inherited]

generate private/public key pair

equivalent to calling GeneratePrivateKey() and then GeneratePublicKey()
