Member Function Documentation

template<class T>

void DL_SimpleKeyAgreementDomainBase< T >::GeneratePrivateKey ( RandomNumberGenerator &  rng, byte *  privateKey  ) const

inlinevirtual

generate private key

Precondition

size of privateKey == PrivateKeyLength()

Implements SimpleKeyAgreementDomain.

Definition at line 1386 of file pubkey.h.

template<class T>

void DL_SimpleKeyAgreementDomainBase< T >::GeneratePublicKey ( RandomNumberGenerator &  rng, const byte *  privateKey, byte *  publicKey  ) const

inlinevirtual

generate public key

Precondition

size of publicKey == PublicKeyLength()

Implements SimpleKeyAgreementDomain.

Definition at line 1392 of file pubkey.h.

template<class T>

bool DL_SimpleKeyAgreementDomainBase< T >::Agree ( byte *  agreedValue, const byte *  privateKey, const byte *  otherPublicKey, bool  validateOtherPublicKey = true  ) const

inlinevirtual

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 1400 of file pubkey.h.

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

virtualinherited

generate private/public key pair

Note

equivalent to calling GeneratePrivateKey() and then GeneratePublicKey()
