X509Certificate
===============

**繼承：** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

X509 憑證（例如用於 TLS）。

.. rst-class:: classref-introduction-group

說明
----

X509Certificate 類代表 X509 憑證。憑證可以像其他的 :ref:`Resource<class_Resource>` 資源一樣載入和保存。

可以用作 :ref:`StreamPeerTLS.accept_stream()<class_StreamPeerTLS_method_accept_stream>` 中的伺服器憑證（搭配正確的 :ref:`CryptoKey<class_CryptoKey>`\ ），也可以用於指定通過 :ref:`StreamPeerTLS.connect_to_stream()<class_StreamPeerTLS_method_connect_to_stream>` 連接到 TLS 伺服器時應該接受的唯一憑證。

.. _class_X509Certificate_method_load:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **load**\ (\ path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_X509Certificate_method_load>`

從路徑 ``path`` 載入憑證（“\*.crt”檔案）。

.. rst-class:: classref-item-separator

----

.. _class_X509Certificate_method_load_from_string:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **load_from_string**\ (\ string\: :ref:`String<class_String>`\ ) :ref:`🔗<class_X509Certificate_method_load_from_string>`

從給定的字串 ``string`` 載入憑證。

.. rst-class:: classref-item-separator

----

.. _class_X509Certificate_method_save:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **save**\ (\ path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_X509Certificate_method_save>`

將憑證保存到給定的路徑 ``path``\ （應該是“\*.crt”檔案）。

.. rst-class:: classref-item-separator

----

.. _class_X509Certificate_method_save_to_string:
