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

Return Values ¶

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

Key		Returned	Description
basic_constraints list		success	Entries in the `basic_constraints` extension, or `none` if extension is not present. Sample: [CA:TRUE, pathlen:1]
basic_constraints_critical boolean		success	Whether the `basic_constraints` extension is critical.
expired boolean		success	Whether the certificate is expired (i.e. `notAfter` is in the past)
extended_key_usage list		success	Entries in the `extended_key_usage` extension, or `none` if extension is not present. Sample: [Biometric Info, DVCS, Time Stamping]
extended_key_usage_critical boolean		success	Whether the `extended_key_usage` extension is critical.
extensions_by_oid complex		success	Returns a dictionary for every extension OID Sample: {"1.3.6.1.5.5.7.1.24": { "critical": false, "value": "MAMCAQU="}}
	critical boolean	success	Whether the extension is critical.
	value string	success	The Base64 encoded value (in DER format) of the extension Sample: MAMCAQU=
issuer dictionary		success	The certificate's issuer. Sample: {"organizationName": "Ansible"}
key_usage string		success	Entries in the `key_usage` extension, or `none` if extension is not present. Sample: [Key Agreement, Data Encipherment]
key_usage_critical boolean		success	Whether the `key_usage` extension is critical.
not_after string		success	`notAfter` date as ASN.1 TIME Sample: 20190413202428Z
not_before string		success	`notBefore` date as ASN.1 TIME Sample: 20190331202428Z
ocsp_must_staple boolean		success	`yes` if the OCSP Must Staple extension is present, `none` otherwise.
ocsp_must_staple_critical boolean		success	Whether the `ocsp_must_staple` extension is critical.
public_key string		success	Certificate's public key in PEM format Sample: -----BEGIN PUBLIC KEY----- MIICIjANBgkqhkiG9w0BAQEFAAOCAg8A...
public_key_fingerprints dictionary		success	Fingerprints of certificate's public key. For every hash algorithm available, the fingerprint is computed. Sample: {'sha256': 'd4:b3:aa:6d:c8:04:ce:4e:ba:f6:29:4d:92:a3:94:b0:c2:ff:bd:bf:33:63:11:43:34:0f:51:b0:95:09:2f:63', 'sha512': 'f7:07:4a:f0:b0:f0:e6:8b:95:5f:f9:e6:61:0a:32:68:f1...
serial_number integer		success	The certificate's serial number. Sample: 1234
signature_algorithm string		success	The signature algorithm used to sign the certificate. Sample: sha256WithRSAEncryption
subject dictionary		success	The certificate's subject. Sample: {"commonName": "www.example.com", "emailAddress": "[email protected]"}
subject_alt_name list		success	Entries in the `subject_alt_name` extension, or `none` if extension is not present. Sample: [DNS:www.ansible.com, IP:1.2.3.4]
