std::unique_ptr<folly::IOBuf> fizz::OpenSSLKeyExchange< T >::generateSharedSecret ( folly::ByteRange  keyShare ) const

inlineoverridevirtual

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.
