# openssl_csr_info – Provide information of OpenSSL Certificate Signing Requests (CSR)

New in version 2.8.

## 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 Ansible 2.13.

## Requirements

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

- PyOpenSSL >= 0.15 or cryptography >= 1.3

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
path path / required |  | Remote absolute path where the CSR file is loaded from.
select_crypto_backend string | Choices: auto ← cryptography pyopenssl | 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 Ansible 2.13. From that point on, only the `cryptography` backend will be available.

  The official documentation on the openssl_csr module.

## Examples

    - name: Generate an OpenSSL Certificate Signing Request
      openssl_csr:
        path: /etc/ssl/csr/www.ansible.com.csr
        privatekey_path: /etc/ssl/private/ansible.com.pem
        common_name: www.ansible.com

    - name: Get information on the CSR
      openssl_csr_info:
        path: /etc/ssl/csr/www.ansible.com.csr
      register: result

    - name: Dump information
      debug:
        var: result

## Return Values

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

Key | Returned | Description
--- | --- | ---
authority_cert_issuer list / elements=string added in 2.9 | success and if the pyOpenSSL backend is not used | The CSR's authority cert issuer as a list of general names. Is `none` if the `AuthorityKeyIdentifier` extension is not present. Sample: [DNS:www.ansible.com, IP:1.2.3.4]
authority_cert_serial_number integer added in 2.9 | success and if the pyOpenSSL backend is not used | The CSR's authority cert serial number. Is `none` if the `AuthorityKeyIdentifier` extension is not present. Sample: 12345
authority_key_identifier string added in 2.9 | success and if the pyOpenSSL backend is not used | 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. 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 | success | Entries in the `basic_constraints` extension, or `none` if extension is not present. Sample: [CA:TRUE, pathlen:1]
basic_constraints_critical boolean | success | Whether the `basic_constraints` extension is critical.
extended_key_usage list / elements=string | success | Entries in the `extended_key_usage` extension, or `none` if extension is not present. Sample: [Biometric Info, DVCS, Time Stamping]
extended_key_usage_critical boolean | success | Whether the `extended_key_usage` extension is critical.
extensions_by_oid dictionary | success | Returns a dictionary for every extension OID Sample: {"1.3.6.1.5.5.7.1.24": { "critical": false, "value": "MAMCAQU="}}
| critical boolean | success | Whether the extension is critical.
| value string | success | The Base64 encoded value (in DER format) of the extension Sample: MAMCAQU=
key_usage string | success | Entries in the `key_usage` extension, or `none` if extension is not present. Sample: [Key Agreement, Data Encipherment]
key_usage_critical boolean | success | Whether the `key_usage` extension is critical.
ocsp_must_staple boolean | success | `yes` if the OCSP Must Staple extension is present, `none` otherwise.
ocsp_must_staple_critical boolean | success | Whether the `ocsp_must_staple` extension is critical.
public_key string | success | CSR's public key in PEM format Sample: -----BEGIN PUBLIC KEY----- MIICIjANBgkqhkiG9w0BAQEFAAOCAg8A...
public_key_fingerprints dictionary | success | Fingerprints of CSR's public key. For every hash algorithm available, the fingerprint is computed. Sample: {'sha256': 'd4:b3:aa:6d:c8:04:ce:4e:ba:f6:29:4d:92:a3:94:b0:c2:ff:bd:bf:33:63:11:43:34:0f:51:b0:95:09:2f:63', 'sha512': 'f7:07:4a:f0:b0:f0:e6:8b:95:5f:f9:e6:61:0a:32:68:f1...
signature_valid boolean | success | Whether the CSR's signature is valid. In case the check returns `no`, the module will fail.
subject dictionary | success | The CSR's subject as a dictionary. Note that for repeated values, only the last one will be returned. Sample: {"commonName": "www.example.com", "emailAddress": "test@example.com"}
subject_alt_name list / elements=string | success | Entries in the `subject_alt_name` extension, or `none` if extension is not present. Sample: [DNS:www.ansible.com, IP:1.2.3.4]
subject_alt_name_critical boolean | success | Whether the `subject_alt_name` extension is critical.
subject_key_identifier string added in 2.9 | success and if the pyOpenSSL backend is not used | The CSR's subject key identifier. The identifier is returned in hexadecimal, with `:` used to separate bytes. Is `none` if the `SubjectKeyIdentifier` extension is not present. Sample: 00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff:00:11:22:33
subject_ordered list / elements=list added in 2.9 | success | The CSR's subject as an ordered list of tuples. Sample: [["commonName", "www.example.com"], ["emailAddress": "test@example.com"]]
