## 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`). Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13.

## 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.
Please note that the `pyopenssl` backend has been deprecated in Ansible 2.9, and will be removed in Ansible 2.13. From that point on, only the `cryptography` backend will be available.

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

## Return Values

Common return values are documented here, the following are the fields unique to this module:
