community.crypto.openssl_privatekey_info – Provide information for OpenSSL private keys

Note

This plugin is part of the community.crypto collection.

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

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

Synopsis

  • This module allows one to query information on OpenSSL private keys.
  • In case the key consistency checks fail, the module will fail as this indicates a faked private key. In this case, all return variables are still returned. Note that key consistency checks are not available all key types; if none is available, none is returned for key_is_consistent.
  • 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 >= 1.2.3

Parameters

Parameter Choices/Defaults Comments
content
string
added in 1.0.0 of community.crypto
Content of the private key file.
Either path or content must be specified, but not both.
passphrase
string
The passphrase for the private key.
path
path
Remote absolute path where the private key file is loaded from.
return_private_key_data
boolean
    Choices:
  • no
  • yes
Whether to return private key data.
Only set this to yes when you want private information about this key to leave the remote machine.
WARNING: you have to make sure that private key data isn't accidentally logged!
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 community.crypto 2.0.0. From that point on, only the cryptography backend will be available.

Examples

- name: Generate an OpenSSL private key with the default values (4096 bits, RSA)
  community.crypto.openssl_privatekey:
    path: /etc/ssl/private/ansible.com.pem

- name: Get information on generated key
  community.crypto.openssl_privatekey_info:
    path: /etc/ssl/private/ansible.com.pem

- 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
can_load_key
boolean
always
Whether the module was able to load the private key from disk

can_parse_key
boolean
always
Whether the module was able to parse the private key

key_is_consistent
boolean
always
Whether the key is consistent. Can also return none next to yes and no, to indicate that consistency couldn't be checked.
In case the check returns no, the module will fail.

private_data
dictionary
success and when return_private_key_data is set to yes
Private key data. Depends on key type.

public_data
dictionary
success
Public key data. Depends on key type.

public_key
string
success
Private key's public key in PEM format

Sample:
-----BEGIN PUBLIC KEY----- MIICIjANBgkqhkiG9w0BAQEFAAOCAg8A...
public_key_fingerprints
dictionary
success
Fingerprints of private key'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...
type
string
success
The key's type.
One of RSA, DSA, ECC, Ed25519, X25519, Ed448, or X448.
Will start with unknown if the key type cannot be determined.

Sample:
RSA
