module: x509_crl
version_added: "2.10"
short_description: Generate Certificate Revocation Lists (CRLs)
description:
- This module allows one to (re)generate or update Certificate Revocation Lists (CRLs).
- Certificates on the revocation list can be either specified via serial number and (optionally) their issuer,
or as a path to a certificate file in PEM format.
requirements:
- cryptography >= 1.2
author:
- Felix Fontein (@felixfontein)
options:
state:
description:
- Whether the CRL file should exist or not, taking action if the state is different from what is stated.
type: str
default: present
choices: [ absent, present ]
mode:
description:
- Defines how to process entries of existing CRLs.
- If set to C(generate), makes sure that the CRL has the exact set of revoked certificates
as specified in I(revoked_certificates).
- If set to C(update), makes sure that the CRL contains the revoked certificates from
I(revoked_certificates), but can also contain other revoked certificates. If the CRL file
already exists, all entries from the existing CRL will also be included in the new CRL.
When using C(update), you might be interested in setting I(ignore_timestamps) to C(yes).
type: str
default: generate
choices: [ generate, update ]
force:
description:
- Should the CRL be forced to be regenerated.
type: bool
default: no
backup:
description:
- Create a backup file including a timestamp so you can get the original
CRL back if you overwrote it with a new one by accident.
type: bool
default: no
path:
description:
- Remote absolute path where the generated CRL file should be created or is already located.
type: path
required: yes
privatekey_path:
description:
- Path to the CA's private key to use when signing the CRL.
- Either I(privatekey_path) or I(privatekey_content) must be specified if I(state) is C(present), but not both.
type: path
privatekey_content:
description:
- The content of the CA's private key to use when signing the CRL.
- Either I(privatekey_path) or I(privatekey_content) must be specified if I(state) is C(present), but not both.
type: str
privatekey_passphrase:
description:
- The passphrase for the I(privatekey_path).
- This is required if the private key is password protected.
type: str
issuer:
description:
- Key/value pairs that will be present in the issuer name field of the CRL.
- If you need to specify more than one value with the same key, use a list as value.
- Required if I(state) is C(present).
type: dict
last_update:
description:
- The point in time from which this CRL can be trusted.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
type: str
default: "+0s"
next_update:
description:
- "The absolute latest point in time by which this I(issuer) is expected to have issued
another CRL. Many clients will treat a CRL as expired once I(next_update) occurs."
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
- Required if I(state) is C(present).
type: str
digest:
description:
- Digest algorithm to be used when signing the CRL.
type: str
default: sha256
revoked_certificates:
description:
- List of certificates to be revoked.
- Required if I(state) is C(present).
type: list
elements: dict
suboptions:
path:
description:
- Path to a certificate in PEM format.
- The serial number and issuer will be extracted from the certificate.
- Mutually exclusive with I(content) and I(serial_number). One of these three options
must be specified.
type: path
content:
description:
- Content of a certificate in PEM format.
- The serial number and issuer will be extracted from the certificate.
- Mutually exclusive with I(path) and I(serial_number). One of these three options
must be specified.
type: str
serial_number:
description:
- Serial number of the certificate.
- Mutually exclusive with I(path) and I(content). One of these three options must
be specified.
type: int
revocation_date:
description:
- The point in time the certificate was revoked.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
type: str
default: "+0s"
issuer:
description:
- The certificate's issuer.
- "Example: C(DNS:ca.example.org)"
type: list

- aa_compromise
- remove_from_crl
reason_critical:
description:
- Whether the revocation reason extension should be critical.
type: bool
default: no
invalidity_date:
description:
- The point in time it was known/suspected that the private key was compromised
or that the certificate otherwise became invalid.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent. This will NOT
change when I(ignore_timestamps) is set to C(yes).
type: str
invalidity_date_critical:
description:
- Whether the invalidity date extension should be critical.
type: bool
default: no
ignore_timestamps:
description:
- Whether the timestamps I(last_update), I(next_update) and I(revocation_date) (in
I(revoked_certificates)) should be ignored for idempotency checks. The timestamp
I(invalidity_date) in I(revoked_certificates) will never be ignored.
- Use this in combination with relative timestamps for these values to get idempotency.
type: bool
default: no
return_content:
description:
- If set to C(yes), will return the (current or generated) CRL's content as I(crl).
type: bool
default: no
extends_documentation_fragment:

notes:
- All ASN.1 TIME values should be specified following the YYYYMMDDHHMMSSZ pattern.
- Date specified should be UTC. Minutes and seconds are mandatory.
