Manage X509 Certificates

.. versionadded:: 2015.8.0

:depends: M2Crypto

.. deprecated:: 3006.0

.. warning::
    This module has been deprecated and will be removed
    in Salt 3009 (Potassium). Please migrate to the replacement
    modules. For breaking changes between both versions,
    you can refer to the :ref:`x509_v2 execution module docs <x509-setup>`.

    They will become the default ``x509`` modules in Salt 3008 (Argon).
    You can explicitly switch to the new modules before that release
    by setting ``features: {x509_v2: true}`` in your minion configuration.


This module can enable managing a complete PKI infrastructure including creating private keys, CAs,
certificates and CRLs. It includes the ability to generate a private key on a server, and have the
corresponding public key sent to a remote CA to create a CA signed certificate. This can be done in
a secure manner, where private keys are always generated locally and never moved across the network.

Here is a simple example scenario. In this example ``ca`` is the ca server,
and ``www`` is a web server that needs a certificate signed by ``ca``.

For remote signing, peers must be permitted to remotely call the
:mod:`sign_remote_certificate <salt.modules.x509.sign_remote_certificate>` function.


/etc/salt/master.d/peer.conf

.. code-block:: yaml

    peer:
      .*:
        - x509.sign_remote_certificate


/srv/salt/top.sls

.. code-block:: yaml

    base:
      '*':
        - cert
      'ca':
        - ca
      'www':
        - www


This state creates the CA key, certificate and signing policy. It also publishes the certificate to
the mine where it can be easily retrieved by other minions.

The signing policy defines properties that override any property requested or included in a CRL. It also
can define a restricted list of minions which are allowed to remotely invoke this signing policy.

This state will instruct all minions to trust certificates signed by our new CA.
Using Jinja to strip newlines from the text avoids dealing with newlines in the rendered YAML,
and the  :mod:`sign_remote_certificate <salt.states.x509.sign_remote_certificate>` state will
handle properly formatting the text before writing the output.

This state creates a private key then requests a certificate signed by ca according to the www policy.

        - days_remaining: 30

This other state creates a private key then requests a certificate signed by ca
according to the www policy but adds a strict date range for the certificate to
be considered valid.
