#include <openssl/ssl.h>

SSL_get_server_tmp_key(SSL *ssl, EVP_PKEY **key);

SSL_get_server_tmp_key() retrieves the temporary key provided by the server and used during key exchange. For example, if ECDHE is in use, this represents the server's public ECDHE key.

In case of success, a copy of the key is stored in *key. It is the caller's responsibility to free this key after use using EVP_PKEY_free(3).

This function may only be called by the client.

This function is implemented as a macro.

SSL_get_server_tmp_key() returns 1 on success or 0 on failure.
