## Synopsis

- Allows to send direct requests to an ACME server with the ACME protocol, which is supported by CAs such as Let’s Encrypt.

- This module can be used to debug failed certificate request attempts, for example when community.crypto.acme_certificate fails or encounters a problem which you wish to investigate.

- The module can also be used to directly access features of an ACME servers which are not yet supported by the Ansible ACME modules.

## Requirements

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

- either openssl or cryptography >= 1.5

- ipaddress

## Parameters

Parameter | Comments
--- | ---

account_key_content

string

Content of the ACME account RSA or Elliptic Curve key.

Mutually exclusive with `account_key_src`.

Required if `account_key_src` is not used.

Warning: the content will be written into a temporary file, which will be deleted by Ansible when the module completes. Since this is an important private key — it can be used to change the account key, or to revoke your certificates without knowing their private keys —, this might not be acceptable.

In case `cryptography` is used, the content is not written into a temporary file. It can still happen that it is written to disk by Ansible in the process of moving the module with its argument to the node where it is executed.

account_key_passphrase string added in community.crypto 1.6.0 | Phassphrase to use to decode the account key. Note: this is not supported by the `openssl` backend, only by the `cryptography` backend.

account_key_src

aliases: account_key

path

Path to a file containing the ACME account RSA or Elliptic Curve key.

Private keys can be created with the community.crypto.openssl_privatekey or community.crypto.openssl_privatekey_pipe modules. If the requisite (cryptography) is not available, keys can also be created directly with the `openssl` command line tool: RSA keys can be created with `openssl genrsa ...`. Elliptic curve keys can be created with `openssl ecparam -genkey ...`. Any other tool creating private keys in PEM format can be used as well.

Mutually exclusive with `account_key_content`.

Required if `account_key_content` is not used.

account_uri string | If specified, assumes that the account URI is as given. If the account key does not match this account, or an account with this URI does not exist, the module fails.

acme_directory

string / required

The ACME directory to use. This is the entry point URL to access the ACME CA server API.

For safety reasons the default is set to the Let’s Encrypt staging server (for the ACME v1 protocol). This will create technically correct, but untrusted certificates.

For Let’s Encrypt, all staging endpoints can be found here: https://letsencrypt.org/docs/staging-environment/. For Buypass, all endpoints can be found here: https://community.buypass.com/t/63d4ay/buypass-go-ssl-endpoints

For Let’s Encrypt, the production directory URL for ACME v2 is https://acme-v02.api.letsencrypt.org/directory.

For Buypass, the production directory URL for ACME v2 and v1 is https://api.buypass.com/acme/directory.

For ZeroSSL, the production directory URL for ACME v2 is https://acme.zerossl.com/v2/DV90.

For Sectigo, the production directory URL for ACME v2 is https://acme-qa.secure.trust-provider.com/v2/DV.

The notes for this module contain a list of ACME services this module has been tested against.

acme_version

integer / required

The ACME version of the endpoint.

Must be `1` for the classic Let’s Encrypt and Buypass ACME endpoints, or `2` for standardized ACME v2 endpoints.

The value `1` is deprecated since community.crypto 2.0.0 and will be removed from community.crypto 3.0.0.

Choices:

- `1`

- `2`

content string | An encoded JSON object which will be sent as the content if method is `post`. Required when method is `post`, and not allowed otherwise.

fail_on_acme_error

boolean

If method is `post` or `get`, make the module fail in case an ACME error is returned.

Choices:

- `false`

- `true` ← (default)

method

string

The method to use to access the given URL on the ACME server.

The value `post` executes an authenticated POST request. The content must be specified in the content option.

The value `get` executes an authenticated POST-as-GET request for ACME v2, and a regular GET request for ACME v1.

The value `directory-only` only retrieves the directory, without doing a request.

Choices:

- `"get"` ← (default)

- `"post"`

- `"directory-only"`

request_timeout integer added in community.crypto 2.3.0 | The time Ansible should wait for a response from the ACME API. This timeout is applied to all HTTP(S) requests (HEAD, GET, POST). Default: `10`

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 `openssl`.

If set to `openssl`, will try to use the `openssl` binary.

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

Choices:

- `"auto"` ← (default)

- `"cryptography"`

- `"openssl"`

url string | The URL to send the request to. Must be specified if method is not `directory-only`.

validate_certs

boolean

Whether calls to the ACME directory will validate TLS certificates.

Warning: Should only ever be set to `false` for testing purposes, for example when testing against a local Pebble server.

Choices:

- `false`

- `true` ← (default)

## Attributes

Attribute | Support | Description
--- | --- | ---
action_group | Action groups: community.crypto.acme, acme | Use `group/acme` or `group/community.crypto.acme` in `module_defaults` to set defaults for this module.
check_mode | Support: none | Can run in `check_mode` and return changed status prediction without modifying target.
diff_mode | Support: none | Will return details on what has changed (or possibly needs changing in `check_mode`), when in diff mode.

## Notes

Note

- The account_uri option must be specified for properly authenticated ACME v2 requests (except a `new-account` request).

- Using the `ansible` tool, community.crypto.acme_inspect can be used to directly execute ACME requests without the need of writing a playbook. For example, the following command retrieves the ACME account with ID 1 from Let’s Encrypt (assuming `/path/to/key` is the correct private account key): `ansible localhost -m acme_inspect -a "account_key_src=/path/to/key acme_directory=https://acme-v02.api.letsencrypt.org/directory acme_version=2 account_uri=https://acme-v02.api.letsencrypt.org/acme/acct/1 method=get url=https://acme-v02.api.letsencrypt.org/acme/acct/1"`

- If a new enough version of the `cryptography` library is available (see Requirements for details), it will be used instead of the `openssl` binary. This can be explicitly disabled or enabled with the `select_crypto_backend` option. Note that using the `openssl` binary will be slower and less secure, as private key contents always have to be stored on disk (see `account_key_content`).

- Although the defaults are chosen so that the module can be used with the Let’s Encrypt CA, the module can in principle be used with any CA providing an ACME endpoint, such as Buypass Go SSL.

- So far, the ACME modules have only been tested by the developers against Let’s Encrypt (staging and production), Buypass (staging and production), ZeroSSL (production), and Pebble testing server. We have got community feedback that they also work with Sectigo ACME Service for InCommon. If you experience problems with another ACME server, please create an issue to help us supporting it. Feedback that an ACME server not mentioned does work is also appreciated.
