community.crypto.openssl_csr_pipe – Generate OpenSSL Certificate Signing Request (CSR)

Note

This plugin is part of the community.crypto collection (version 1.7.0).

To install it use: ansible-galaxy collection install community.crypto.

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

New in version 1.3.0: of community.crypto

Synopsis

  • Please note that the module regenerates an existing CSR if it doesn’t match the module’s options, or if it seems to be corrupt.

  • The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. This can be overridden with the select_crypto_backend option. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in community.crypto 2.0.0.

  • This module allows one to (re)generate OpenSSL certificate signing requests.

  • This module supports the subjectAltName, keyUsage, extendedKeyUsage, basicConstraints and OCSP Must Staple extensions.

Requirements

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

  • Either cryptography >= 1.3

  • Or pyOpenSSL >= 0.15

Parameters

authority_cert_issuer
list / elements=string

The only allowed value according to RFC 2986 is 1.
This option will no longer accept unsupported values from community.crypto 2.0.0 on.

Notes

Note

  • If the certificate signing request already exists it will be checked whether subjectAltName, keyUsage, extendedKeyUsage and basicConstraints only contain the requested values, whether OCSP Must Staple is as requested, and if the request was signed by the given private key.
