community.crypto.x509_certificate_info module – Provide information of OpenSSL X.509 certificates

Note

This module is part of the community.crypto collection (version 2.3.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.crypto.

To use it in a playbook, specify: community.crypto.x509_certificate_info.

Synopsis

  • This module allows one to query information on OpenSSL certificates.

  • It uses the cryptography python library to interact with OpenSSL.

  • Note that this module was called openssl_certificate_info when included directly in Ansible up to version 2.9. When moved to the collection community.crypto, it was renamed to community.crypto.x509_certificate_info. From Ansible 2.10 on, it can still be used by the old short name (or by ansible.builtin.openssl_certificate_info), which redirects to community.crypto.x509_certificate_info. When using FQCNs or when using the collections keyword, the new name community.crypto.x509_certificate_info should be used to avoid a deprecation warning.

Requirements

The below requirements are needed on the host that executes this module.

  • If name_encoding is set to another value than ignore, the idna Python library needs to be installed.

  • cryptography >= 1.6

Parameters

Parameter

Comments

content

string

added in 1.0.0 of community.crypto

Content of the X.509 certificate in PEM format.

Either path or content must be specified, but not both.

name_encoding

string

How to encode names (DNS names, URIs, email addresses) in return values.

ignore will use the encoding returned by the backend.

idna will convert all labels of domain names to IDNA encoding. IDNA2008 will be preferred, and IDNA2003 will be used if IDNA2008 encoding fails.

unicode will convert all labels of domain names to Unicode. IDNA2008 will be preferred, and IDNA2003 will be used if IDNA2008 decoding fails.

Note that idna and unicode require the idna Python library to be installed.

Choices:

  • ignore ← (default)

  • idna

  • unicode

path

path

Remote absolute path where the certificate file is loaded from.

Either path or content must be specified, but not both.

select_crypto_backend

string

Determines which crypto backend to use.

The default choice is auto, which tries to use cryptography if available.

If set to cryptography, will try to use the cryptography library.

Choices:

  • auto ← (default)

  • cryptography

valid_at

dictionary

A dict of names mapping to time specifications. Every time specified here will be checked whether the certificate is valid at this point. See the valid_at return value for informations on the result.

Time can be specified either as relative time or as absolute timestamp.

Time will always be interpreted as UTC.

Valid format is [+-]timespec | ASN.1 TIME where timespec can be an integer + [w | d | h | m | s] (for example +32w1d2h), and ASN.1 TIME (in other words, pattern YYYYMMDDHHMMSSZ). Note that all timestamps will be treated as being in UTC.

Notes

Note

  • All timestamp values are provided in ASN.1 TIME format, in other words, following the YYYYMMDDHHMMSSZ pattern. They are all in UTC.

  • Supports check_mode.

Examples

- name: Generate a Self Signed OpenSSL certificate
  community.crypto.x509_certificate:
    path: /etc/ssl/crt/ansible.com.crt
    privatekey_path: /etc/ssl/private/ansible.com.pem
    csr_path: /etc/ssl/csr/ansible.com.csr
    provider: selfsigned


# Get information on the certificate

- name: Get information on generated certificate
  community.crypto.x509_certificate_info:
    path: /etc/ssl/crt/ansible.com.crt
  register: result

- name: Dump information
  ansible.builtin.debug:
    var: result


# Check whether the certificate is valid or not valid at certain times, fail
# if this is not the case. The first task (x509_certificate_info) collects
# the information, and the second task (assert) validates the result and
# makes the playbook fail in case something is not as expected.

- name: Test whether that certificate is valid tomorrow and/or in three weeks
  community.crypto.x509_certificate_info:
    path: /etc/ssl/crt/ansible.com.crt
    valid_at:
      point_1: "+1d"
      point_2: "+3w"
  register: result

- name: Validate that certificate is valid tomorrow, but not in three weeks
  assert:
    that:
      - result.valid_at.point_1      # valid in one day
      - not result.valid_at.point_2  # not valid in three weeks
