Release 2.15.0.

* Check return code on ssh(-keygen) invocations.

* openssh_cert: only check for errors if certificate should be present and module is not in check mode.

* Handle rc check for _get_private_key().

* Add changelog fragment.

* Only pass -o for comment updating when necessary.

* Now fails if comment cannot be updated.

This was silently ignored in the past.

* Avoid failing operation.

+v2.14.1
+=======
+
+Release Summary
+---------------
+
+Bugfix and maintenance release with updated documentation.
+
+From this version on, community.crypto is using the new `Ansible semantic markup
+<https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_documenting.html#semantic-markup-within-module-documentation>`__
+in its documentation. If you look at documentation with the ansible-doc CLI tool
+from ansible-core before 2.15, please note that it does not render the markup
+correctly. You should be still able to read it in most cases, but you need
+ansible-core 2.15 or later to see it as it is intended. Alternatively you can
+look at `the devel docsite <https://docs.ansible.com/ansible/devel/collections/community/crypto/>`__
+for the rendered HTML version of the documentation of the latest release.
+
+
+Bugfixes
+--------
+
+- Fix PEM detection/identification to also accept random other lines before the line starting with ``-----BEGIN`` (https://github.com/ansible-collections/community.crypto/issues/627, https://github.com/ansible-collections/community.crypto/pull/628).
+
+Known Issues
+------------
+
+- Ansible markup will show up in raw form on ansible-doc text output for ansible-core before 2.15. If you have trouble deciphering the documentation markup, please upgrade to ansible-core 2.15 (or newer), or read the HTML documentation on https://docs.ansible.com/ansible/devel/collections/community/crypto/.
+
+v2.14.0
+=======
+
+Release Summary
+---------------
+
+Feature release.
+
+Minor Changes
+-------------
+
+- acme_certificate - allow to use no challenge by providing ``no challenge`` for the ``challenge`` option. This is needed for ACME servers where validation is done without challenges (https://github.com/ansible-collections/community.crypto/issues/613, https://github.com/ansible-collections/community.crypto/pull/615).
+- acme_certificate - validate and wait for challenges in parallel instead handling them one after another (https://github.com/ansible-collections/community.crypto/pull/617).

+---------------
+
+Bugfix and maintenance release.
+
+Minor Changes
+-------------
+
+- x509_crl - the ``crl_mode`` option has been added to replace the existing ``mode`` option (https://github.com/ansible-collections/community.crypto/issues/596).
+
+Deprecated Features
+-------------------
+
+- x509_crl - the ``mode`` option is deprecated; use ``crl_mode`` instead. The ``mode`` option will change its meaning in community.crypto 3.0.0, and will refer to the CRL file's mode instead (https://github.com/ansible-collections/community.crypto/issues/596).
+
+Bugfixes
+--------
+
+- openssh_keypair - always generate a new key pair if the private key does not exist. Previously, the module would fail when ``regenerate=fail`` without an existing key, contradicting the documentation (https://github.com/ansible-collections/community.crypto/pull/598).
+- x509_crl - remove problem with ansible-core 2.16 due to ``AnsibleModule`` is now validating the ``mode`` parameter's values (https://github.com/ansible-collections/community.crypto/issues/596).

+- acme_* modules - include symbolic HTTP status codes in error and log messages when available (https://github.com/ansible-collections/community.crypto/pull/524).
+- openssl_pkcs12 - add option ``encryption_level`` which allows to chose ``compatibility2022`` when cryptography >= 38.0.0 is used to enable a more backwards compatible encryption algorithm. If cryptography uses OpenSSL 3.0.0 or newer, the default algorithm is not compatible with older software (https://github.com/ansible-collections/community.crypto/pull/523).
+
+v2.7.1
+======
+
+Release Summary
+---------------
+
+Maintenance release.
+
+Bugfixes

+
+Bugfixes
+--------
+
+- openssl_privatekey_pipe - ensure compatibility with newer versions of ansible-core (https://github.com/ansible-collections/community.crypto/pull/515).

+
+Release Summary
+---------------
+
+Maintenance release with improved licensing declaration and documentation fixes.
+
+Minor Changes
+-------------
+
+- All software licenses are now in the ``LICENSES/`` directory of the collection root. Moreover, ``SPDX-License-Identifier:`` is used to declare the applicable license for every file that is not automatically generated (https://github.com/ansible-collections/community.crypto/pull/491).
+
+v2.4.0
+======
+
+Release Summary
+---------------
+
+Deprecation and bugfix release. No new features this time.
+
+Deprecated Features
+-------------------
+
+- Support for Ansible 2.9 and ansible-base 2.10 is deprecated, and will be removed in the next major release (community.crypto 3.0.0). Some modules might still work with these versions afterwards, but we will no longer keep compatibility code that was needed to support them (https://github.com/ansible-collections/community.crypto/pull/460).
+
+Bugfixes
+--------
+
+- openssl_pkcs12 - when using the pyOpenSSL backend, do not crash when trying to read non-existing other certificates (https://github.com/ansible-collections/community.crypto/issues/486, https://github.com/ansible-collections/community.crypto/pull/487).
+
+v2.3.4
+======
+
+Release Summary
+---------------
+
+Re-release of what was intended to be 2.3.3.
+
+A mistake during the release process caused the 2.3.3 tag to end up on the
+commit for 1.9.17, which caused the release pipeline to re-publish 1.9.17
+as 2.3.3.
+
+This release is identical to what should have been 2.3.3, except that the
+version number has been bumped to 2.3.4 and this changelog entry for 2.3.4
+has been added.
+
+
+v2.3.3
+======
+
+Release Summary
+---------------
+
+Bugfix release.
+
+Bugfixes
+--------
+
+- Include ``Apache-2.0.txt`` file for ``plugins/module_utils/crypto/_obj2txt.py`` and ``plugins/module_utils/crypto/_objects_data.py``.
+- openssl_csr - the module no longer crashes with 'permitted_subtrees/excluded_subtrees must be a non-empty list or None' if only one of ``name_constraints_permitted`` and ``name_constraints_excluded`` is provided (https://github.com/ansible-collections/community.crypto/issues/481).
+- x509_crl - do not crash when signing CRL with Ed25519 or Ed448 keys (https://github.com/ansible-collections/community.crypto/issues/473, https://github.com/ansible-collections/community.crypto/pull/474).

+
+v2.3.1
+======
+
+Release Summary
+---------------
+
+Maintenance release.
+
+Bugfixes
+--------
+
+- Include ``PSF-license.txt`` file for ``plugins/module_utils/_version.py``.
+
+v2.3.0
+======
+
+Release Summary
+---------------
+
+Feature and bugfix release.
+
+Minor Changes
+-------------
+
+- Prepare collection for inclusion in an Execution Environment by declaring its dependencies. Please note that system packages are used for cryptography and PyOpenSSL, which can be rather limited. If you need features from newer cryptography versions, you will have to manually force a newer version to be installed by pip by specifying something like ``cryptography >= 37.0.0`` in your Execution Environment's Python dependencies file (https://github.com/ansible-collections/community.crypto/pull/440).
+- Support automatic conversion for Internalionalized Domain Names (IDNs). When passing general names, for example Subject Altenative Names to ``community.crypto.openssl_csr``, these will automatically be converted to IDNA. Conversion will be done per label to IDNA2008 if possible, and IDNA2003 if IDNA2008 conversion fails for that label. Note that IDNA conversion requires `the Python idna library <https://pypi.org/project/idna/>`_ to be installed. Please note that depending on which versions of the cryptography library are used, it could try to process the converted IDNA another time with the Python ``idna`` library and reject IDNA2003 encoded values. Using a new enough ``cryptography`` version avoids this (https://github.com/ansible-collections/community.crypto/issues/426, https://github.com/ansible-collections/community.crypto/pull/436).
+- acme_* modules - add parameter ``request_timeout`` to manage HTTP(S) request timeout (https://github.com/ansible-collections/community.crypto/issues/447, https://github.com/ansible-collections/community.crypto/pull/448).
+- luks_devices - added ``perf_same_cpu_crypt``, ``perf_submit_from_crypt_cpus``, ``perf_no_read_workqueue``, ``perf_no_write_workqueue`` for performance tuning when opening LUKS2 containers (https://github.com/ansible-collections/community.crypto/issues/427).
+- luks_devices - added ``persistent`` option when opening LUKS2 containers (https://github.com/ansible-collections/community.crypto/pull/434).
+- openssl_csr_info - add ``name_encoding`` option to control the encoding (IDNA, Unicode) used to return domain names in general names (https://github.com/ansible-collections/community.crypto/pull/436).
+- openssl_pkcs12 - allow to provide the private key as text instead of having to read it from a file. This allows to store the private key in an encrypted form, for example in Ansible Vault (https://github.com/ansible-collections/community.crypto/pull/452).
+- x509_certificate_info - add ``name_encoding`` option to control the encoding (IDNA, Unicode) used to return domain names in general names (https://github.com/ansible-collections/community.crypto/pull/436).
+- x509_crl - add ``name_encoding`` option to control the encoding (IDNA, Unicode) used to return domain names in general names (https://github.com/ansible-collections/community.crypto/pull/436).
+- x509_crl_info - add ``name_encoding`` option to control the encoding (IDNA, Unicode) used to return domain names in general names (https://github.com/ansible-collections/community.crypto/pull/436).
+
+Bugfixes
+--------
+
+- Make collection more robust when PyOpenSSL is used with an incompatible cryptography version (https://github.com/ansible-collections/community.crypto/pull/445).
+- x509_crl - fix crash when ``issuer`` for a revoked certificate is specified (https://github.com/ansible-collections/community.crypto/pull/441).
+
+v2.2.4
+======
+
+Release Summary
+---------------
+
+Regular maintenance release.
+
+Bugfixes
+--------
+
+- openssh_* modules - fix exception handling to report traceback to users for enhanced traceability (https://github.com/ansible-collections/community.crypto/pull/417).
+
+v2.2.3
+======
+
+Release Summary
+---------------
+
+Regular bugfix release.
+
+Bugfixes
+--------
+
+- luks_device - fix parsing of ``lsblk`` output when device name ends with ``crypt`` (https://github.com/ansible-collections/community.crypto/issues/409, https://github.com/ansible-collections/community.crypto/pull/410).
+
+v2.2.2
+======
+
+Release Summary
+---------------
+
+Regular bugfix release.
+
+In this release, we extended the test matrix to include Alpine 3, ArchLinux, Debian Bullseye, and CentOS Stream 8. CentOS 8 was removed from the test matrix.
+
+
+Bugfixes
+--------
+
+- certificate_complete_chain - allow multiple potential intermediate certificates to have the same subject (https://github.com/ansible-collections/community.crypto/issues/399, https://github.com/ansible-collections/community.crypto/pull/403).
+- x509_certificate - for the ``ownca`` provider, check whether the CA private key actually belongs to the CA certificate (https://github.com/ansible-collections/community.crypto/pull/407).
+- x509_certificate - regenerate certificate when the CA's public key changes for ``provider=ownca`` (https://github.com/ansible-collections/community.crypto/pull/407).
+- x509_certificate - regenerate certificate when the CA's subject changes for ``provider=ownca`` (https://github.com/ansible-collections/community.crypto/issues/400, https://github.com/ansible-collections/community.crypto/pull/402).
+- x509_certificate - regenerate certificate when the private key changes for ``provider=selfsigned`` (https://github.com/ansible-collections/community.crypto/pull/407).
+
+v2.2.1
+======
+
+Release Summary
+---------------
+
+Bugfix release.
+
+Bugfixes
+--------
+
+- openssh_cert - fixed false ``changed`` status for ``host`` certificates when using ``full_idempotence`` (https://github.com/ansible-collections/community.crypto/issues/395, https://github.com/ansible-collections/community.crypto/pull/396).
+
+v2.2.0
+======
+
+Release Summary
+---------------
+
+Regular bugfix and feature release.
+
+Minor Changes
+-------------
+
+- openssh_cert - added ``ignore_timestamps`` parameter so it can be used semi-idempotent with relative timestamps in ``valid_to``/``valid_from`` (https://github.com/ansible-collections/community.crypto/issues/379).
+
+Bugfixes
+--------
+
+- luks_devices - set ``LANG`` and similar environment variables to avoid translated output, which can break some of the module's functionality like key management (https://github.com/ansible-collections/community.crypto/pull/388, https://github.com/ansible-collections/community.crypto/issues/385).
+
+v2.1.0
+======
+
+Release Summary
+---------------
+
+Feature and bugfix release.
+
+Minor Changes
+-------------
+
+- Adjust error messages that indicate ``cryptography`` is not installed from ``Can't`` to ``Cannot`` (https://github.com/ansible-collections/community.crypto/pull/374).
+
+Bugfixes
+--------
+
+- Various modules and plugins - use vendored version of ``distutils.version`` instead of the deprecated Python standard library ``distutils`` (https://github.com/ansible-collections/community.crypto/pull/353).
+- certificate_complete_chain - do not append root twice if the chain already ends with a root certificate (https://github.com/ansible-collections/community.crypto/pull/360).
+- certificate_complete_chain - do not hang when infinite loop is found (https://github.com/ansible-collections/community.crypto/issues/355, https://github.com/ansible-collections/community.crypto/pull/360).
+
+New Modules
+-----------
+
+- crypto_info - Retrieve cryptographic capabilities

+
+v2.0.2
+======
+
+Release Summary
+---------------
+
+Documentation fix release. No actual code changes.
+
+v2.0.1
+======
+
+Release Summary
+---------------
+
+Bugfix release with extra forward compatibility for newer versions of cryptography.
+
+Minor Changes
+-------------
+
+- acme_* modules - fix usage of ``fetch_url`` with changes in latest ansible-core ``devel`` branch (https://github.com/ansible-collections/community.crypto/pull/339).
+
+Bugfixes
+--------
+
+- acme_certificate - avoid passing multiple certificates to ``cryptography``'s X.509 certificate loader when ``fullchain_dest`` is used (https://github.com/ansible-collections/community.crypto/pull/324).
+- get_certificate, openssl_csr_info, x509_certificate_info - add fallback code for extension parsing that works with cryptography 36.0.0 and newer. This code re-serializes de-serialized extensions and thus can return slightly different values if the extension in the original CSR resp. certificate was not canonicalized correctly. This code is currently used as a fallback if the existing code stops working, but we will switch it to be the main code in a future release (https://github.com/ansible-collections/community.crypto/pull/331).
+- luks_device - now also runs a built-in LUKS signature cleaner on ``state=absent`` to make sure that also the secondary LUKS2 header is wiped when older versions of wipefs are used (https://github.com/ansible-collections/community.crypto/issues/326, https://github.com/ansible-collections/community.crypto/pull/327).
+- openssl_pkcs12 - use new PKCS#12 deserialization infrastructure from cryptography 36.0.0 if available (https://github.com/ansible-collections/community.crypto/pull/302).
+
+v2.0.0
+======
+
+Release Summary
+---------------
+
+A new major release of the ``community.crypto`` collection. The main changes are removal of the PyOpenSSL backends for almost all modules (``openssl_pkcs12`` being the only exception), and removal of the ``assertonly`` provider in the ``x509_certificate`` provider. There are also some other breaking changes which should improve the user interface/experience of this collection long-term.
+
+
+Minor Changes
+-------------
+
+- acme_certificate - the ``subject`` and ``issuer`` fields in in the ``select_chain`` entries are now more strictly validated (https://github.com/ansible-collections/community.crypto/pull/316).
+- openssl_csr, openssl_csr_pipe - provide a new ``subject_ordered`` option if the order of the components in the subject is of importance (https://github.com/ansible-collections/community.crypto/issues/291, https://github.com/ansible-collections/community.crypto/pull/316).
+- openssl_csr, openssl_csr_pipe - there is now stricter validation of the values of the ``subject`` option (https://github.com/ansible-collections/community.crypto/pull/316).
+- openssl_privatekey_info - add ``check_consistency`` option to request private key consistency checks to be done (https://github.com/ansible-collections/community.crypto/pull/309).
+- x509_certificate, x509_certificate_pipe - add ``ignore_timestamps`` option which allows to enable idempotency for 'not before' and 'not after' options (https://github.com/ansible-collections/community.crypto/issues/295, https://github.com/ansible-collections/community.crypto/pull/317).
+- x509_crl - provide a new ``issuer_ordered`` option if the order of the components in the issuer is of importance (https://github.com/ansible-collections/community.crypto/issues/291, https://github.com/ansible-collections/community.crypto/pull/316).
+- x509_crl - there is now stricter validation of the values of the ``issuer`` option (https://github.com/ansible-collections/community.crypto/pull/316).
+
+Breaking Changes / Porting Guide
+--------------------------------
+
+- Adjust ``dirName`` text parsing and to text converting code to conform to `Sections 2 and 3 of RFC 4514 <https://datatracker.ietf.org/doc/html/rfc4514.html>`_. This is similar to how `cryptography handles this <https://cryptography.io/en/latest/x509/reference/#cryptography.x509.Name.rfc4514_string>`_ (https://github.com/ansible-collections/community.crypto/pull/274).
+- acme module utils - removing compatibility code (https://github.com/ansible-collections/community.crypto/pull/290).
+- acme_* modules - removed vendored copy of the Python library ``ipaddress``. If you are using Python 2.x, please make sure to install the library (https://github.com/ansible-collections/community.crypto/pull/287).
+- compatibility module_utils - removed vendored copy of the Python library ``ipaddress`` (https://github.com/ansible-collections/community.crypto/pull/287).
+- crypto module utils - removing compatibility code (https://github.com/ansible-collections/community.crypto/pull/290).
+- get_certificate, openssl_csr_info, x509_certificate_info - depending on the ``cryptography`` version used, the modules might not return the ASN.1 value for an extension as contained in the certificate respectively CSR, but a re-encoded version of it. This should usually be identical to the value contained in the source file, unless the value was malformed. For extensions not handled by C(cryptography) the value contained in the source file is always returned unaltered (https://github.com/ansible-collections/community.crypto/pull/318).
+- module_utils - removed various PyOpenSSL support functions and default backend values that are not needed for the openssl_pkcs12 module (https://github.com/ansible-collections/community.crypto/pull/273).
+- openssl_csr, openssl_csr_pipe, x509_crl - the ``subject`` respectively ``issuer`` fields no longer ignore empty values, but instead fail when encountering them (https://github.com/ansible-collections/community.crypto/pull/316).
+- openssl_privatekey_info - by default consistency checks are not run; they need to be explicitly requested by passing ``check_consistency=true`` (https://github.com/ansible-collections/community.crypto/pull/309).
+- x509_crl - for idempotency checks, the ``issuer`` order is ignored. If order is important, use the new ``issuer_ordered`` option (https://github.com/ansible-collections/community.crypto/pull/316).
+
+Deprecated Features
+-------------------
+
+- acme_* modules - ACME version 1 is now deprecated and support for it will be removed in community.crypto 2.0.0 (https://github.com/ansible-collections/community.crypto/pull/288).

+--------
+
+- openssl_csr - no longer fails when comparing CSR without basic constraint when ``basic_constraints`` is specified (https://github.com/ansible-collections/community.crypto/issues/179, https://github.com/ansible-collections/community.crypto/pull/180).
+
+v1.4.0
+======
+
+Release Summary
+---------------
+
+Release with several new features and bugfixes.
+
+Minor Changes
+-------------
+
+- The ACME module_utils has been relicensed back from the Simplified BSD License (https://opensource.org/licenses/BSD-2-Clause) to the GPLv3+ (same license used by most other code in this collection). This undoes a licensing change when the original GPLv3+ licensed code was moved to module_utils in https://github.com/ansible/ansible/pull/40697 (https://github.com/ansible-collections/community.crypto/pull/165).
+- The ``crypto/identify.py`` module_utils has been renamed to ``crypto/pem.py`` (https://github.com/ansible-collections/community.crypto/pull/166).
+- luks_device - ``new_keyfile``, ``new_passphrase``, ``remove_keyfile`` and ``remove_passphrase`` are now idempotent (https://github.com/ansible-collections/community.crypto/issues/19, https://github.com/ansible-collections/community.crypto/pull/168).

+
+Bugfixes
+--------
+
+- acme_certificate - error when requested challenge type is not found for non-valid challenges, instead of hanging on step 2 (https://github.com/ansible-collections/community.crypto/issues/171, https://github.com/ansible-collections/community.crypto/pull/173).
+
+v1.3.0
+======
+
+Release Summary
+---------------
+
+Contains new modules ``openssl_privatekey_pipe``, ``openssl_csr_pipe`` and ``x509_certificate_pipe`` which allow to create or update private keys, CSRs and X.509 certificates without having to write them to disk.
+
+
+Minor Changes
+-------------
+
+- openssh_cert - add module parameter ``use_agent`` to enable using signing keys stored in ssh-agent (https://github.com/ansible-collections/community.crypto/issues/116).
+- openssl_csr - refactor module to allow code re-use by openssl_csr_pipe (https://github.com/ansible-collections/community.crypto/pull/123).
+- openssl_privatekey - refactor module to allow code re-use by openssl_privatekey_pipe (https://github.com/ansible-collections/community.crypto/pull/119).
+- openssl_privatekey - the elliptic curve ``secp192r1`` now triggers a security warning. Elliptic curves of at least 224 bits should be used for new keys; see `here <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ec.html#elliptic-curves>`_ (https://github.com/ansible-collections/community.crypto/pull/132).
+- x509_certificate - for the ``selfsigned`` provider, a CSR is not required anymore. If no CSR is provided, the module behaves as if a minimal CSR which only contains the public key has been provided (https://github.com/ansible-collections/community.crypto/issues/32, https://github.com/ansible-collections/community.crypto/pull/129).
+- x509_certificate - refactor module to allow code re-use by x509_certificate_pipe (https://github.com/ansible-collections/community.crypto/pull/135).
+
+Bugfixes
+--------
+
+- openssl_pkcs12 - report the correct state when ``action`` is ``parse`` (https://github.com/ansible-collections/community.crypto/issues/143).
+- support code - improve handling of certificate and certificate signing request (CSR) loading with the ``cryptography`` backend when errors occur (https://github.com/ansible-collections/community.crypto/issues/138, https://github.com/ansible-collections/community.crypto/pull/139).
+- x509_certificate - fix ``entrust`` provider, which was broken since community.crypto 0.1.0 due to a feature added before the collection move (https://github.com/ansible-collections/community.crypto/pull/135).
+
+New Modules
+-----------
+
+- openssl_csr_pipe - Generate OpenSSL Certificate Signing Request (CSR)
+- openssl_privatekey_pipe - Generate OpenSSL private keys without disk access
+- x509_certificate_pipe - Generate and/or check OpenSSL certificates
+
+v1.2.0
+======
+

+- x509_certificate_info - add ``fingerprints`` return value which returns certificate fingerprints (https://github.com/ansible-collections/community.crypto/pull/121).
+
+Security Fixes
+--------------
+
+- openssl_csr - the option ``privatekey_content`` was not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+- openssl_privatekey_info - the option ``content`` was not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+- openssl_publickey - the option ``privatekey_content`` was not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+- openssl_signature - the option ``privatekey_content`` was not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+- x509_certificate - the options ``privatekey_content`` and ``ownca_privatekey_content`` were not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+- x509_crl - the option ``privatekey_content`` was not marked as ``no_log``, resulting in it being dumped into the system log by default, and returned in the registered results in the ``invocation`` field (CVE-2020-25646, https://github.com/ansible-collections/community.crypto/pull/125).
+
+Bugfixes
+--------
+
+- openssl_pkcs12 - do not crash when reading PKCS#12 file which has no private key and/or no main certificate (https://github.com/ansible-collections/community.crypto/issues/103).

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+How to create a small CA
+========================
+
+The `community.crypto collection <https://galaxy.ansible.com/community/crypto>`_ offers multiple modules that create private keys, certificate signing requests, and certificates. This guide shows how to create your own small CA and how to use it to sign certificates.
+
+In all examples, we assume that the CA's private key is password protected, where the password is provided in the ``secret_ca_passphrase`` variable.
+
+Set up the CA
+-------------
+
+Any certificate can be used as a CA certificate. You can create a self-signed certificate (see :ref:`ansible_collections.community.crypto.docsite.guide_selfsigned`), use another CA certificate to sign a new certificate (using the instructions below for signing a certificate), ask (and pay) a commercial CA to sign your CA certificate, etc.
+
+The following instructions show how to set up a simple self-signed CA certificate.
+
+.. code-block:: yaml+jinja
+
+    - name: Create private key with password protection
+      community.crypto.openssl_privatekey:
+        path: /path/to/ca-certificate.key
+        passphrase: "{{ secret_ca_passphrase }}"
+
+    - name: Create certificate signing request (CSR) for CA certificate
+      community.crypto.openssl_csr_pipe:
+        privatekey_path: /path/to/ca-certificate.key
+        privatekey_passphrase: "{{ secret_ca_passphrase }}"
+        common_name: Ansible CA
+        use_common_name_for_san: false  # since we do not specify SANs, don't use CN as a SAN
+        basic_constraints:
+          - 'CA:TRUE'
+        basic_constraints_critical: true
+        key_usage:
+          - keyCertSign
+        key_usage_critical: true
+      register: ca_csr
+
+    - name: Create self-signed CA certificate from CSR
+      community.crypto.x509_certificate:
+        path: /path/to/ca-certificate.pem
+        csr_content: "{{ ca_csr.csr }}"
+        privatekey_path: /path/to/ca-certificate.key
+        privatekey_passphrase: "{{ secret_ca_passphrase }}"
+        provider: selfsigned
+
+Use the CA to sign a certificate
+--------------------------------
+
+To sign a certificate, you must pass a CSR to the :ref:`community.crypto.x509_certificate module <ansible_collections.community.crypto.x509_certificate_module>` or :ref:`community.crypto.x509_certificate_pipe module <ansible_collections.community.crypto.x509_certificate_pipe_module>`.
+
+In the following example, we assume that the certificate to sign (including its private key) are on ``server_1``, while our CA certificate is on ``server_2``. We do not want any key material to leave each respective server.
+
+.. code-block:: yaml+jinja
+
+    - name: Create private key for new certificate on server_1
+      community.crypto.openssl_privatekey:
+        path: /path/to/certificate.key
+      delegate_to: server_1
+      run_once: true
+
+    - name: Create certificate signing request (CSR) for new certificate
+      community.crypto.openssl_csr_pipe:
+        privatekey_path: /path/to/certificate.key
+        subject_alt_name:
+          - "DNS:ansible.com"
+          - "DNS:www.ansible.com"
+          - "DNS:docs.ansible.com"
+      delegate_to: server_1

+
+How to create self-signed certificates
+======================================
+
+The `community.crypto collection <https://galaxy.ansible.com/community/crypto>`_ offers multiple modules that create private keys, certificate signing requests, and certificates. This guide shows how to create self-signed certificates.
+
+For creating any kind of certificate, you always have to start with a private key. You can use the :ref:`community.crypto.openssl_privatekey module <ansible_collections.community.crypto.openssl_privatekey_module>` to create a private key. If you only specify :ansopt:`community.crypto.openssl_privatekey#module:path`, the default parameters will be used. This will result in a 4096 bit RSA private key:
+
+.. code-block:: yaml+jinja
+
+    - name: Create private key (RSA, 4096 bits)
+      community.crypto.openssl_privatekey:
+        path: /path/to/certificate.key
+
+You can specify :ansopt:`community.crypto.openssl_privatekey#module:type` to select another key type, :ansopt:`community.crypto.openssl_privatekey#module:size` to select a different key size (only available for RSA and DSA keys), or :ansopt:`community.crypto.openssl_privatekey#module:passphrase` if you want to store the key password-protected:
+
+.. code-block:: yaml+jinja
+
+    - name: Create private key (X25519) with password protection
+      community.crypto.openssl_privatekey:
+        path: /path/to/certificate.key
+        type: X25519
+        passphrase: changeme
+
+To create a very simple self-signed certificate with no specific information, you can proceed directly with the :ref:`community.crypto.x509_certificate module <ansible_collections.community.crypto.x509_certificate_module>`:
+
+.. code-block:: yaml+jinja
+
+    - name: Create simple self-signed certificate
+      community.crypto.x509_certificate:
+        path: /path/to/certificate.pem
+        privatekey_path: /path/to/certificate.key
+        provider: selfsigned
+
+(If you used :ansopt:`community.crypto.openssl_privatekey#module:passphrase` for the private key, you have to provide :ansopt:`community.crypto.x509_certificate#module:privatekey_passphrase`.)
+
+You can use :ansopt:`community.crypto.x509_certificate#module:selfsigned_not_after` to define when the certificate expires (default: in roughly 10 years), and :ansopt:`community.crypto.x509_certificate#module:selfsigned_not_before` to define from when the certificate is valid (default: now).
+
+To define further properties of the certificate, like the subject, Subject Alternative Names (SANs), key usages, name constraints, etc., you need to first create a Certificate Signing Request (CSR) and provide it to the :ref:`community.crypto.x509_certificate module <ansible_collections.community.crypto.x509_certificate_module>`. If you do not need the CSR file, you can use the :ref:`community.crypto.openssl_csr_pipe module <ansible_collections.community.crypto.openssl_csr_pipe_module>` as in the example below. (To store it to disk, use the :ref:`community.crypto.openssl_csr module <ansible_collections.community.crypto.openssl_csr_module>` instead.)
+
+.. code-block:: yaml+jinja
+
+    - name: Create certificate signing request (CSR) for self-signed certificate
+      community.crypto.openssl_csr_pipe:
+        privatekey_path: /path/to/certificate.key
+        common_name: ansible.com
+        organization_name: Ansible, Inc.
+        subject_alt_name:
+          - "DNS:ansible.com"
+          - "DNS:www.ansible.com"
+          - "DNS:docs.ansible.com"
+      register: csr
+
+    - name: Create self-signed certificate from CSR
+      community.crypto.x509_certificate:
+        path: /path/to/certificate.pem
+        csr_content: "{{ csr.csr }}"
+        privatekey_path: /path/to/certificate.key
+        provider: selfsigned

+              is protected by an unknown passphrase, or when they key is not protected by a passphrase,

+            - If set to V(always), the module will always regenerate the key. This is equivalent to

+
+# The rules according to Greg Stein:
+# 1) a version number has 1 or more numbers separated by a period or by
+#    sequences of letters. If only periods, then these are compared
+#    left-to-right to determine an ordering.
+# 2) sequences of letters are part of the tuple for comparison and are
+#    compared lexicographically
+# 3) recognize the numeric components may have leading zeroes
+#
+# The LooseVersion class below implements these rules: a version number
+# string is split up into a tuple of integer and string components, and
+# comparison is a simple tuple comparison.  This means that version
+# numbers behave in a predictable and obvious way, but a way that might
+# not necessarily be how people *want* version numbers to behave.  There
+# wouldn't be a problem if people could stick to purely numeric version
+# numbers: just split on period and compare the numbers as tuples.
+# However, people insist on putting letters into their version numbers;
+# the most common purpose seems to be:
+#   - indicating a "pre-release" version
+#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')
+#   - indicating a post-release patch ('p', 'pl', 'patch')
+# but of course this can't cover all version number schemes, and there's
+# no way to know what a programmer means without asking him.
+#
+# The problem is what to do with letters (and other non-numeric
+# characters) in a version number.  The current implementation does the
+# obvious and predictable thing: keep them as strings and compare
+# lexically within a tuple comparison.  This has the desired effect if
+# an appended letter sequence implies something "post-release":
+# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
+#
+# However, if letters in a version number imply a pre-release version,
+# the "obvious" thing isn't correct.  Eg. you would expect that
+# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
+# implemented here, this just isn't so.
+#
+# Two possible solutions come to mind.  The first is to tie the
+# comparison algorithm to a particular set of semantic rules, as has
+# been done in the StrictVersion class above.  This works great as long
+# as everyone can go along with bondage and discipline.  Hopefully a
+# (large) subset of Python module programmers will agree that the
+# particular flavour of bondage and discipline provided by StrictVersion
+# provides enough benefit to be worth using, and will submit their
+# version numbering scheme to its domination.  The free-thinking
+# anarchists in the lot will never give in, though, and something needs
+# to be done to accommodate them.
+#
+# Perhaps a "moderately strict" version class could be implemented that
+# lets almost anything slide (syntactically), and makes some heuristic
+# assumptions about non-digits in version number strings.  This could
+# sink into special-case-hell, though; if I was as talented and
+# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
+# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
+# just as happy dealing with things like "2g6" and "1.13++".  I don't
+# think I'm smart enough to do it right though.
+#
+# In any case, I've coded the test suite for this module (see
+# ../test/test_version.py) specifically to fail on things like comparing
+# "1.2a2" and "1.2".  That's not because the *code* is doing anything
+# wrong, it's because the simple, obvious design doesn't match my
+# complicated, hairy expectations for real-world version numbers.  It
+# would be a snap to fix the test suite to say, "Yep, LooseVersion does
+# the Right Thing" (ie. the code matches the conception).  But I'd rather
+# have a conception that matches common notions about version numbers.

+class LooseVersion(Version):
+    """Version numbering for anarchists and software realists.
+    Implements the standard interface for version number classes as
+    described above.  A version number consists of a series of numbers,
+    separated by either periods or strings of letters.  When comparing
+    version numbers, the numeric components will be compared
