module: openssl_certificate
version_added: "2.4"
short_description: Generate and/or check OpenSSL certificates
description:
- This module allows one to (re)generate OpenSSL certificates.
- It implements a notion of provider (ie. C(selfsigned), C(ownca), C(acme), C(assertonly), C(entrust))
for your certificate.
- The C(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 C(assertonly) usage with M(openssl_certificate_info), M(openssl_csr_info),
M(openssl_privatekey_info) and M(assert). This also allows more flexible checks than
the ones offered by the C(assertonly) provider.
- The C(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 I(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 C(select_crypto_backend)).
Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13.
requirements:
- PyOpenSSL >= 0.15 or cryptography >= 1.6 (if using C(selfsigned) or C(assertonly) provider)
- acme-tiny (if using the C(acme) provider)

- Time will always be interpreted as UTC.
- Note that only the date (day, month, year) is supported for specifying the expiry date of the issued certificate.
- The full date-time is adjusted to EST (GMT -5:00) before issuance, which may result in a certificate with an expiration date one day
earlier than expected if a relative time is used.

notes:
- 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 C(ownca) provider, you should NOT run M(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.

# (Please note that assertonly has been deprecated!)

- 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

key_usage:
- digitalSignature
- keyEncipherment
