Returns true if the real and effective group IDs of a process may be exchanged on the current platform.
Derives a shared secret by ECDH. pubkey must be an instance of OpenSSL::PKey::EC::Point and must belong to the same group.
This method is provided for backwards compatibility, and calls derive internally.
