Member Function Documentation

virtual void fizz::KeyExchange::generateKeyPair ( )
pure virtual

Generates an ephemeral key pair.

Implemented in fizz::OpenSSLKeyExchange< T >, and fizz::X25519KeyExchange.

virtual std::unique_ptr<folly::IOBuf> fizz::KeyExchange::generateSharedSecret ( folly::ByteRange  keyShare) const
pure virtual

Generate a shared secret with our key pair and a peer's public key share.

Performs all necessary validation of the public key share and throws on error.

generateKeyPair() must be called before.

Implemented in fizz::OpenSSLKeyExchange< T >, and fizz::X25519KeyExchange.

virtual std::unique_ptr<folly::IOBuf> fizz::KeyExchange::getKeyShare ( ) const
pure virtual

Returns the public key to share with peers.

generateKeyPair() must be called before.

Implemented in fizz::OpenSSLKeyExchange< T >, and fizz::X25519KeyExchange.
