Inheritance diagram for SimpleKeyAgreementDomain:
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.

Public Member Functions | |
virtual unsigned int | AgreedValueLength () const=0 |
return length of agreed value produced | |
virtual unsigned int | PrivateKeyLength () const=0 |
return length of private keys in this domain | |
virtual unsigned int | PublicKeyLength () const=0 |
return length of public keys in this domain | |
virtual void | GeneratePrivateKey (RandomNumberGenerator &rng, byte *privateKey) const =0 |
generate private key | |
virtual void | GeneratePublicKey (RandomNumberGenerator &rng, const byte *privateKey, byte *publicKey) const =0 |
generate public key | |
virtual void | GenerateKeyPair (RandomNumberGenerator &rng, byte *privateKey, byte *publicKey) const |
generate private/public key pair | |
virtual bool | Agree (byte *agreedValue, const byte *privateKey, const byte *otherPublicKey, bool validateOtherPublicKey=true) const =0 |
derive agreed value from your private key and couterparty's public key, return false in case of failure | |
