For example, if ECDHE is in use, then this represents the peer's public ECDHE key. On success a pointer to the key is stored in <strong>*key</strong>. It is the caller's responsibility to free this key after use using <em>EVP_PKEY_free(3)</em>.</p> <p><code>SSL_get_server_tmp_key()</code> is a backwards compatibility alias for <code>SSL_get_peer_tmp_key()</code>.
