Yanis Guenane 3e4a306a42 openssl_certificate: Correctly set the version (#30314) 
Current openssl_certificate is mistakenly taking its derivating its
version number from the csr version number.

Thos two fields are completly unrelated and hence the version number of
the certificate should be able to be directly specified (via
selfsigned_version parameter).

module: openssl_certificate
author:
- Yanis Guenane (@Spredzy)
- Markus Teufelberger (@MarkusTeufelberger)
version_added: "2.4"
short_description: Generate and/or check OpenSSL certificates
description:
- "This module allows one to (re)generate OpenSSL certificates. It implements a notion
of provider (ie. C(selfsigned), C(acme), C(assertonly)) for your certificate.
The 'assertonly' provider is intended for use cases where one is only interested in
checking properties of a supplied certificate.
Many properties that can be specified in this module are for validation of an
existing or newly generated certificate. The proper place to specify them, if you
want to receive a certificate with these properties is a CSR (Certificate Signing Request).
It uses the pyOpenSSL python library to interact with OpenSSL."
requirements:
- python-pyOpenSSL >= 0.15 (if using C(selfsigned) or C(assertonly) provider)
- acme-tiny (if using the C(acme) provider)
options:
state:
default: "present"
choices: [ present, absent ]
description:
- Whether the certificate should exist or not, taking action if the state is different from what is stated.
path:
required: true
description:
- Remote absolute path where the generated certificate file should be created or is already located.
provider:
required: true
choices: [ 'selfsigned', 'assertonly', 'acme' ]
description:
- Name of the provider to use to generate/retrieve the OpenSSL certificate.
The C(assertonly) provider will not generate files and fail if the certificate file is missing.
force:
default: False
type: bool
description:
- Generate the certificate, even if it already exists.
csr_path:
description:
- Path to the Certificate Signing Request (CSR) used to generate this certificate. This is not required in C(assertonly) mode.
privatekey_path:
description:
- Path to the private key to use when signing the certificate.
privatekey_passphrase:
description:
- The passphrase for the I(privatekey_path).
selfsigned_version:
default: 3
description:
- Version of the C(selfsigned) certificate. Nowadays it should almost always be C(3).
version_added: "2.5"
selfsigned_digest:
default: "sha256"
description:
- Digest algorithm to be used when self-signing the certificate
selfsigned_not_before:
description:
- The timestamp at which the certificate starts being valid. The timestamp is formatted as an ASN.1 TIME.
If this value is not specified, certificate will start being valid from now.
aliases: [ selfsigned_notBefore ]
selfsigned_not_after:
description:
- The timestamp at which the certificate stops being valid. The timestamp is formatted as an ASN.1 TIME.
If this value is not specified, certificate will stop being valid 10 years from now.
aliases: [ selfsigned_notAfter ]
acme_accountkey:
description:
- Path to the accountkey for the C(acme) provider
acme_challenge_path:
description:
- Path to the ACME challenge directory that is served on U(http://<HOST>:80/.well-known/acme-challenge/)
signature_algorithms:
description:
- list of algorithms that you would accept the certificate to be signed with
(e.g. ['sha256WithRSAEncryption', 'sha512WithRSAEncryption']).
issuer:
description:
- Key/value pairs that must be present in the issuer name field of the certificate
subject:
description:
- Key/value pairs that must be present in the subject name field of the certificate
has_expired:
default: False
type: bool
description:
- Checks if the certificate is expired/not expired at the time the module is executed.
version:
description:
- Version of the certificate. Nowadays it should almost always be 3.
valid_at:
description:
- The certificate must be valid at this point in time. The timestamp is formatted as an ASN.1 TIME.
invalid_at:
description:
- The certificate must be invalid at this point in time. The timestamp is formatted as an ASN.1 TIME.
not_before:
description:
- The certificate must start to become valid at this point in time. The timestamp is formatted as an ASN.1 TIME.
aliases: [ notBefore ]
not_after:
description:
- The certificate must expire at this point in time. The timestamp is formatted as an ASN.1 TIME.
aliases: [ notAfter ]
valid_in:
description:
- The certificate must still be valid in I(valid_in) seconds from now.
key_usage:
description:
- The I(key_usage) extension field must contain all these values.
aliases: [ keyUsage ]
