Detailed Description

abstract base class for domains of simple key agreement protocols.

A key agreement domain is a set of parameters that must be shared by two parties in a key agreement protocol, along with the algorithms for generating key pairs and deriving agreed values.

Member Function Documentation

bool PK_SimpleKeyAgreementDomain::Agree ( byte * agreedValue, const byte * privateKey, const byte * otherPublicKey, bool validateOtherPublicKey = true ) const [pure 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. /*! Preconditions: \begin{itemize} \item size of agreedValue == AgreedValueLength() \item length of privateKey == PrivateKeyLength() \item length of otherPublicKey == PublicKeyLength() \end{itemize} Reimplemented in LUCDIF, and XTR_DH. Referenced by DH2::Agree().

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

generate private/public key pair. Preconditions: \begin{itemize} \item size of privateKey == PrivateKeyLength() \item size of publicKey == PublicKeyLength() \end{itemize} Reimplemented in LUCDIF, and XTR_DH. Referenced by DH2::GenerateEphemeralKeyPair(), and DH2::GenerateStaticKeyPair().
