Member Function Documentation

template<class T> void DL_SimpleKeyAgreementDomainBase< T >::GeneratePrivateKey (  RandomNumberGenerator &  rng, byte *  privateKey )  const [inline, virtual]

generate private key Precondition: size of privateKey == PrivateKeyLength() Implements SimpleKeyAgreementDomain. Definition at line 1358 of file pubkey.h.

template<class T> void DL_SimpleKeyAgreementDomainBase< T >::GeneratePublicKey (  RandomNumberGenerator &  rng, const byte *  privateKey, byte *  publicKey )  const [inline, virtual]

generate public key Precondition: size of publicKey == PublicKeyLength() Implements SimpleKeyAgreementDomain. Reimplemented in DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >. Definition at line 1364 of file pubkey.h.

template<class T> bool DL_SimpleKeyAgreementDomainBase< T >::Agree (  byte *  agreedValue, const byte *  privateKey, const byte *  otherPublicKey, bool  validateOtherPublicKey = true )  const [inline, virtual]

derive agreed value from your private key and couterparty's public key, return false in case of failure Note: If you have previously validated the public key, use validateOtherPublicKey=false to save time. /*! Precondition: size of agreedValue == AgreedValueLength() length of privateKey == PrivateKeyLength() length of otherPublicKey == PublicKeyLength() Implements SimpleKeyAgreementDomain. Definition at line 1372 of file pubkey.h.

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

generate private/public key pair Note: equivalent to calling GeneratePrivateKey() and then GeneratePublicKey() Definition at line 645 of file cryptlib.cpp. References SimpleKeyAgreementDomain::GeneratePrivateKey(), and SimpleKeyAgreementDomain::GeneratePublicKey(). Referenced by DH2::GenerateEphemeralKeyPair(), and DH2::GenerateStaticKeyPair().
