community.crypto.x509_certificate module – Generate and/or check OpenSSL certificates

Note

This module is part of the community.crypto collection (version 2.18.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.crypto. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.crypto.x509_certificate.

Synopsis

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

  • It uses the cryptography python library to interact with OpenSSL.

  • Note that this module was called openssl_certificate when included directly in Ansible up to version 2.9. When moved to the collection community.crypto, it was renamed to community.crypto.x509_certificate. From Ansible 2.10 on, it can still be used by the old short name (or by ansible.builtin.openssl_certificate), which redirects to community.crypto.x509_certificate. When using FQCNs or when using the collections keyword, the new name community.crypto.x509_certificate should be used to avoid a deprecation warning.

  • Please note that the module regenerates existing certificate if it does not 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.

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

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

Requirements

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

  • acme-tiny >= 4.0.0 (if using the acme provider)

  • cryptography >= 1.6 (if using selfsigned or ownca provider)

Parameters

Parameter

Comments

acme_accountkey_path

path

This is only used by the acme provider.

acme_chain

boolean

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 true results in an error.

Choices:

You can use this to keep a local copy of the specification to avoid downloading it every time the module is used.

This is only used by the entrust provider.

Default: "https://cloud.entrust.net/EntrustCloud/documentation/cms-api-2.1.0.yaml"

entrust_api_user

string

The username for authentication to the Entrust Certificate Services (ECS) API.

  • "WILDCARD_SSL"

  • "PRIVATE_SSL"

  • "PD_SSL"

  • "CDS_ENT_LITE"

  • "CDS_ENT_PRO"

  • "SMIME_ENT"

entrust_not_after

string

The point in time at which the certificate stops being valid.

Time can be specified either as relative time or as an absolute timestamp.

A valid absolute time format is ASN.1 TIME such as 2019-06-18.

A valid relative time format is [+-]timespec where timespec can be an integer + [w | d | h | m | s], such as +365d or +32w1d2h).

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.

The minimum certificate lifetime is 90 days, and maximum is three years.

If this value is not specified, the certificate will stop being valid 365 days the date of issue.

This is only used by the entrust provider.

Please note that this value is not covered by the ignore_timestamps option.

Default: "+365d"

entrust_requester_email

string

The email of the requester of the certificate (for tracking purposes).

This is only used by the entrust provider.

This is required if the provider is entrust.

force

boolean

Generate the certificate, even if it already exists.

Choices:

  • false ← (default)

  • true

group

string

Name of the group that should own the filesystem object, as would be fed to chown.

When left unspecified, it uses the current group of the current user unless you are root, in which case it can preserve the previous ownership.

ignore_timestamps

boolean

added in community.crypto 2.0.0

Whether the “not before” and “not after” timestamps should be ignored for idempotency checks.

It is better to keep the default value true when using relative timestamps (like +0s for now).

Choices:

  • false

  • true ← (default)

mode

any

The permissions the resulting filesystem object should have.

For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must give Ansible enough information to parse them correctly. For consistent results, quote octal numbers (for example, '644' or '1777') so Ansible receives a string and can do its own conversion from string into number. Adding a leading zero (for example, 0755) works sometimes, but can fail in loops and some other circumstances.

Giving Ansible a number without following either 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).

If mode is not specified and the destination filesystem object does not exist, the default umask on the system will be used when setting the mode for the newly created filesystem object.

If mode is not specified and the destination filesystem object does exist, the mode of the existing filesystem object will be used.

Specifying mode is the best way to ensure filesystem objects are created with the correct permissions. See CVE-2020-1736 for further details.

ownca_content

string

added in community.crypto 1.0.0

Content of the CA (Certificate Authority) certificate.

This is only used by the ownca provider.

This is mutually exclusive with ownca_path.

ownca_create_authority_key_identifier

boolean

Create a Authority Key Identifier from the CA’s certificate. If the CSR provided a authority key identifier, it is ignored.

The Authority Key Identifier is generated from the CA certificate’s Subject Key Identifier, if available. If it is not available, the CA certificate’s public key will be used.

This is only used by the ownca provider.

Note that this is only supported if the cryptography backend is used!

Choices:

  • false

  • true ← (default)

ownca_create_subject_key_identifier

string

Whether to create the Subject Key Identifier (SKI) from the public key.

A value of create_if_not_provided (default) only creates a SKI when the CSR does not provide one.

A value of always_create always creates a SKI. If the CSR provides one, that one is ignored.

A value of never_create never creates a SKI. If the CSR provides one, that one is used.

This is only used by the ownca provider.

Note that this is only supported if the cryptography backend is used!

Choices:

  • "create_if_not_provided" ← (default)

  • "always_create"

  • "never_create"

string

The digest algorithm to be used for the ownca certificate.

This is only used by the ownca provider.

Default: "sha256"

ownca_not_after

string

The point in time at which the certificate stops being valid.

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] (for example +32w1d2h).

If this value is not specified, the certificate will stop being valid 10 years from now.

Note that this value is not used to determine whether an existing certificate should be regenerated. This can be changed by setting the ignore_timestamps option to false. Please note that you should avoid relative timestamps when setting ignore_timestamps=false.

This is only used by the ownca provider.

On macOS 10.15 and onwards, TLS server certificates must have a validity period of 825 days or fewer. Please see https://support.apple.com/en-us/HT210176 for more details.

Default: "+3650d"

ownca_not_before

string

The point in time the certificate is valid from.

Time can be specified either as relative time or as absolute timestamp.

Valid format is [+-]timespec | ASN.1 TIME where timespec can be an integer + [w | d | h | m | s] (for example +32w1d2h).

If this value is not specified, the certificate will start being valid from now.

Note that this value is not used to determine whether an existing certificate should be regenerated. This can be changed by setting the ignore_timestamps option to false. Please note that you should avoid relative timestamps when setting ignore_timestamps=false.

This is only used by the ownca provider.

Default: "+0s"

Choices:

  • "absent"

  • "present" ← (default)

unsafe_writes

boolean

Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target filesystem object.

By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target filesystem objects, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted filesystem objects, 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 filesystem objects 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.

Choices:

  • false ← (default)

  • true

Attributes

Attribute

Support

Description

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: full

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

safe_file_operations

Support: full

Uses Ansible’s strict file operation functions to ensure proper permissions and avoid data corruption.

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 community.crypto.x509_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.

  • For the selfsigned provider, csr_path and csr_content are optional. If not provided, a certificate without any information (Subject, Subject Alternative Names, Key Usage, etc.) is created.
