community.crypto.openssl_csr_info module – Provide information of OpenSSL Certificate Signing Requests (CSR)

Note

This module is part of the community.crypto collection (version 2.9.0).

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.openssl_csr_info.

Synopsis

  • This module allows one to query information on OpenSSL Certificate Signing Requests (CSR).

  • In case the CSR signature cannot be validated, the module will fail. In this case, all return variables are still returned.

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

Requirements

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

  • If name_encoding is set to another value than ignore, the idna Python library needs to be installed.

  • cryptography >= 1.3

Parameters

Parameter

Comments

content

string

added in community.crypto 1.0.0

Content of the CSR file.

Either path or content must be specified, but not both.

name_encoding

string

How to encode names (DNS names, URIs, email addresses) in return values.

ignore will use the encoding returned by the backend.

idna will convert all labels of domain names to IDNA encoding. IDNA2008 will be preferred, and IDNA2003 will be used if IDNA2008 encoding fails.

unicode will convert all labels of domain names to Unicode. IDNA2008 will be preferred, and IDNA2003 will be used if IDNA2008 decoding fails.

Note that idna and unicode require the idna Python library to be installed.

Choices:

  • "ignore" ← (default)

  • "idna"

  • "unicode"

path

path

Remote absolute path where the CSR file is loaded from.

Either path or content must be specified, but not both.

select_crypto_backend

string

Determines which crypto backend to use.

The default choice is auto, which tries to use cryptography if available.

If set to cryptography, will try to use the cryptography library.

Choices:

  • "auto" ← (default)

  • "cryptography"

Return Values

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

Key

Description

authority_cert_issuer

list / elements=string

The CSR’s authority cert issuer as a list of general names.

Is none if the AuthorityKeyIdentifier extension is not present.

See name_encoding for how IDNs are handled.

Returned: success

Sample: ["DNS:www.ansible.com", "IP:1.2.3.4"]

authority_cert_serial_number

integer

The CSR’s authority cert serial number.

Is none if the AuthorityKeyIdentifier extension is not present.

Returned: success

Sample: 12345

authority_key_identifier

string

The CSR’s authority key identifier.

The identifier is returned in hexadecimal, with : used to separate bytes.

Is none if the AuthorityKeyIdentifier extension is not present.

Returned: success

Sample: "00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff:00:11:22:33"

basic_constraints

list / elements=string

Entries in the basic_constraints extension, or none if extension is not present.

Returned: success

Sample: ["CA:TRUE", "pathlen:1"]

basic_constraints_critical

boolean

Whether the basic_constraints extension is critical.

Returned: success

extended_key_usage

list / elements=string

Entries in the extended_key_usage extension, or none if extension is not present.

Returned: success

Sample: ["Biometric Info", "DVCS", "Time Stamping"]

extended_key_usage_critical

Whether the extended_key_usage extension is critical.

Returned: success

extensions_by_oid

dictionary

Returns a dictionary for every extension OID

Returned: success

Sample: {"1.3.6.1.5.5.7.1.24": {"critical": false, "value": "MAMCAQU="}}

critical

boolean

Whether the extension is critical.

Returned: success

value

string

The Base64 encoded value (in DER format) of the extension.

Note that depending on the cryptography version used, it is not possible to extract the ASN.1 content of the extension, but only to provide the re-encoded content of the extension in case it was parsed by cryptography. This should usually result in exactly the same value, except if the original extension value was malformed.

Returned: success

Sample: "MAMCAQU="

key_usage

string

Entries in the key_usage extension, or none if extension is not present.

Returned: success

Sample: "['Key Agreement', 'Data Encipherment']"

key_usage_critical

boolean

Whether the key_usage extension is critical.

Returned: success

name_constraints_critical

boolean

added in community.crypto 1.1.0

Is none if extension is not present.

Returned: success

name_constraints_excluded

list / elements=string

added in community.crypto 1.1.0
