CryptoKey
=========

**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

A cryptographic key (RSA).

Description
-----------

The CryptoKey class represents a cryptographic key. Keys can be loaded and saved like any other :ref:`Resource<class_Resource>`.

They can be used to generate a self-signed :ref:`X509Certificate<class_X509Certificate>` via :ref:`Crypto.generate_self_signed_certificate<class_Crypto_method_generate_self_signed_certificate>` and as private key in :ref:`StreamPeerSSL.accept_stream<class_StreamPeerSSL_method_accept_stream>` along with the appropriate certificate.

Method Descriptions
-------------------

.. _class_CryptoKey_method_is_public_only:

- :ref:`bool<class_bool>` **is_public_only** **(** **)** |const|

Return ``true`` if this CryptoKey only has the public part, and not the private one.

----

.. _class_CryptoKey_method_load:

- :ref:`Error<enum_@GlobalScope_Error>` **load** **(** :ref:`String<class_String>` path, :ref:`bool<class_bool>` public_only=false **)**

Loads a key from ``path``. If ``public_only`` is ``true``, only the public key will be loaded.

\ **Note:** ``path`` should be a "\*.pub" file if ``public_only`` is ``true``, a "\*.key" file otherwise.

----

.. _class_CryptoKey_method_load_from_string:

- :ref:`Error<enum_@GlobalScope_Error>` **load_from_string** **(** :ref:`String<class_String>` string_key, :ref:`bool<class_bool>` public_only=false **)**

Loads a key from the given ``string``. If ``public_only`` is ``true``, only the public key will be loaded.

----

.. _class_CryptoKey_method_save:

- :ref:`Error<enum_@GlobalScope_Error>` **save** **(** :ref:`String<class_String>` path, :ref:`bool<class_bool>` public_only=false **)**

Saves a key to the given ``path``. If ``public_only`` is ``true``, only the public key will be saved.

\ **Note:** ``path`` should be a "\*.pub" file if ``public_only`` is ``true``, a "\*.key" file otherwise.

----

.. _class_CryptoKey_method_save_to_string:

- :ref:`String<class_String>` **save_to_string** **(** :ref:`bool<class_bool>` public_only=false **)**

Returns a string containing the key in PEM format. If ``public_only`` is ``true``, only the public key will be included.
