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()
