+.Sh SYNOPSIS
+.In openssl/ssl.h
+.Ft long
+.Fo SSL_get_server_tmp_key
+.Fa "SSL *ssl"
+.Fa "EVP_PKEY **key"
+.Fc
+.Sh DESCRIPTION
+.Fn 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.
+.Pp
+In case of success, a copy of the key is stored in
+.Pf * Fa key .
+It is the caller's responsibility to free this key after use using
+.Xr EVP_PKEY_free 3 .
+.Pp
+This function may only be called by the client.
+.Pp
+This function is implemented as a macro.
+.Sh RETURN VALUES
