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

Note

This plugin is part of the community.crypto collection (version 1.9.8).

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.

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 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 community.crypto 2.0.0.

Requirements

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

  • PyOpenSSL >= 0.15 or cryptography >= 1.3

Parameters

Parameter

Comments

content

string

added in 1.0.0 of community.crypto

Content of the CSR file.

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

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, and falls back to pyopenssl.

If set to pyopenssl, will try to use the pyOpenSSL library.

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

Please note that the pyopenssl backend has been deprecated in Ansible 2.9, and will be removed in community.crypto 2.0.0. From that point on, only the cryptography backend will be available.

Choices:

  • auto ← (default)

  • cryptography

  • pyopenssl
