openssl_certificate – Generate and/or check OpenSSL certificates

New in version 2.4.

Synopsis

  • This module allows one to (re)generate OpenSSL certificates.

  • It implements a notion of provider (ie. selfsigned, ownca, acme, assertonly, entrust) for your certificate.

  • The assertonly provider is intended for use cases where one is only interested in checking properties of a supplied certificate. Please note that this provider has been deprecated in Ansible 2.9 and will be removed in Ansible 2.13. See the examples on how to emulate assertonly usage with openssl_certificate_info, openssl_csr_info, openssl_privatekey_info and assert. This also allows more flexible checks than the ones offered by the assertonly provider.

  • The ownca provider is intended for generating OpenSSL certificate signed with your own CA (Certificate Authority) certificate (self-signed certificate).

  • Many properties that can be specified in this module are for validation of an existing or newly generated certificate. The proper place to specify them, if you want to receive a certificate with these properties is a CSR (Certificate Signing Request).

  • Please note that the module regenerates existing certificate if it doesn’t match the module’s options, or if it seems to be corrupt. If you are concerned that this could overwrite your existing certificate, consider using the backup option.

  • 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 (if using selfsigned or assertonly provider)

  • acme-tiny (if using the acme provider)

Parameters

Parameter Choices/Defaults Comments
acme_accountkey_path
path
The path to the accountkey for the acme provider.
This is only used by the acme provider.
acme_chain
boolean
added in 2.5
    Choices:
  • no ←
  • yes
Include the intermediate certificate to the generated certificate
This is only used by the acme provider.
Note that this is only available for older versions of acme-tiny. New versions include the chain automatically, and setting acme_chain to yes results in an error.
acme_challenge_path
path
The path to the ACME challenge directory that is served on
attributes
string
The attributes the resulting file or directory should have.
To get supported flags look at the man page for chattr on the target system.

aliases: keyUsage_strict
mode
string
The permissions the resulting file or directory should have.
For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number.
Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results.
As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).

unsafe_writes
boolean
    Choices:
  • no ←
  • yes
Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file.
By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner.
This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes).
IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption.

The certificate must be valid at this point in time.
The timestamp is formatted as an ASN.1 TIME.
This is only used by the assertonly provider.
This option is deprecated since Ansible 2.9 and will be removed with the assertonly provider in Ansible 2.13. For alternatives, see the example on replacing assertonly.
valid_in

Note that if using this parameter, this module is NOT idempotent.
This is only used by the assertonly provider.
This option is deprecated since Ansible 2.9 and will be removed with the assertonly provider in Ansible 2.13. For alternatives, see the example on replacing assertonly.
version
integer
The version of the certificate.
Nowadays it should almost always be 3.
This is only used by the assertonly provider.
This option is deprecated since Ansible 2.9 and will be removed with the assertonly provider in Ansible 2.13. For alternatives, see the example on replacing assertonly.

Notes

Note

  • All ASN.1 TIME values should be specified following the YYYYMMDDHHMMSSZ pattern.

  • Date specified should be UTC. Minutes and seconds are mandatory.

  • For security reason, when you use ownca provider, you should NOT run openssl_certificate on a target machine, but on a dedicated CA machine. It is recommended not to store the CA private key on the target machine. Once signed, the certificate can be moved to the target machine.

# Examples for some checks one could use the assertonly provider for:
# (Please note that assertonly has been deprecated!)

# How to use the assertonly provider to implement and trigger your own custom certificate generation workflow:
- name: Check if a certificate is currently still valid, ignoring failures
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    has_expired: no
  ignore_errors: yes
  register: validity_check

- name: Run custom task(s) to get a new, valid certificate in case the initial check failed
  command: superspecialSSL recreate /etc/ssl/crt/example.com.crt
  when: validity_check.failed

- name: Check the new certificate again for validity with the same parameters, this time failing the play if it is still invalid
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    has_expired: no
  when: validity_check.failed

# Some other checks that assertonly could be used for:
- name: Verify that an existing certificate was issued by the Let's Encrypt CA and is currently still valid
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    issuer:
      O: Let's Encrypt
    has_expired: no

- name: Ensure that a certificate uses a modern signature algorithm (no SHA1, MD5 or DSA)
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    signature_algorithms:
      - sha224WithRSAEncryption
      - sha256WithRSAEncryption
      - sha384WithRSAEncryption
      - sha512WithRSAEncryption
      - sha224WithECDSAEncryption
      - sha256WithECDSAEncryption
      - sha384WithECDSAEncryption
      - sha512WithECDSAEncryption

- name: Ensure that the existing certificate belongs to the specified private key
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    privatekey_path: /etc/ssl/private/example.com.pem
    provider: assertonly

- name: Ensure that the existing certificate is still valid at the winter solstice 2017
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    valid_at: 20171221162800Z

- name: Ensure that the existing certificate is still valid 2 weeks (1209600 seconds) from now
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    valid_in: 1209600

- name: Ensure that the existing certificate is only used for digital signatures and encrypting other keys
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    key_usage:
      - digitalSignature
      - keyEncipherment
    key_usage_strict: true

- name: Ensure that the existing certificate can be used for client authentication
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    extended_key_usage:
      - clientAuth

- name: Ensure that the existing certificate can only be used for client authentication and time stamping
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    extended_key_usage:
      - clientAuth
      - 1.3.6.1.5.5.7.3.8
    extended_key_usage_strict: true

- name: Ensure that the existing certificate has a certain domain in its subjectAltName
  openssl_certificate:
    path: /etc/ssl/crt/example.com.crt
    provider: assertonly
    subject_alt_name:
      - www.example.com
      - test.example.com
