openssl_certificate_info – Provide information of OpenSSL X.509 certificates

New in version 2.8.

Synopsis

  • This module allows one to query information on OpenSSL certificates.
  • It uses the pyOpenSSL or cryptography python library to interact with OpenSSL. If both the cryptography and PyOpenSSL libraries are available (and meet the minimum version requirements) cryptography will be preferred as a backend over PyOpenSSL (unless the backend is forced with select_crypto_backend)

Requirements

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

  • PyOpenSSL >= 0.15 or cryptography >= 1.6

Parameters

Parameter Choices/Defaults Comments
path
path / required
Remote absolute path where the certificate file is loaded from.
select_crypto_backend
string
    Choices:
  • auto ←
  • cryptography
  • pyopenssl
Determines which crypto backend to use.
The default choice is auto, which tries to use cryptography if available, and falls back to pyopenssl.
If set to pyopenssl, will try to use the pyOpenSSL library.
If set to cryptography, will try to use the cryptography library.
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] (e.g. +32w1d2h, and ASN.1 TIME (i.e. 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, i.e. following the YYYYMMDDHHMMSSZ pattern. They are all in UTC.

Examples

- name: Generate a Self Signed OpenSSL certificate
  openssl_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
  openssl_certificate_info:
    path: /etc/ssl/crt/ansible.com.crt
  register: result

- name: Dump information
  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 (openssl_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
  openssl_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
