WebbEVP_PKEY_get0_engine () returns a reference to the ENGINE handling pkey. This function is deprecated. Applications should use providers instead of engines (see provider (7) for details). EVP_PKEY_set1_engine () sets the ENGINE handling pkey to engine. It must be called after the key algorithm and components are set up.
