openssl_privatekey - Generate OpenSSL private keys.

New in version 2.3.

Synopsis

  • This module allows one to (re)generate OpenSSL private keys. It uses the pyOpenSSL python library to interact with openssl. One can generate either RSA or DSA private keys. Keys are generated in PEM format.

Requirements

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

  • python-pyOpenSSL

Parameters

Parameter Choices/Defaults Comments
attributes
(added in 2.3)
 Default:
None
Attributes the file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr.

aliases: attr
cipher
(added in 2.4)
The cipher to encrypt the private key. (cipher can be found by running `openssl list-cipher-algorithms`)
force
    Choices:
  • yes
  • no ←
Default:
no
Should the key be regenerated even it it already exists
group Default:
None
Name of the group that should own the file/directory, as would be fed to chown.
mode Default:
None
Mode the file or directory should be. For those used to /usr/bin/chmod remember that modes are actually octal numbers (like 0644 or 01777). Leaving off the leading zero will likely have unexpected results. As of version 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).
owner Default:
None
Name of the user that should own the file/directory, as would be fed to chown.
passphrase
(added in 2.4)
The passphrase for the private key.
path
required
Name of the file in which the generated TLS/SSL private key will be written. It will have 0600 mode.
selevel Default:
s0
Level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range. _default feature works as for seuser.
serole Default:
None
Role part of SELinux file context, _default feature works as for seuser.
setype Default:
None
Type part of SELinux file context, _default feature works as for seuser.
seuser Default:
None
User part of SELinux file context. Will default to system policy, if applicable. If set to _default, it will use the user portion of the policy if available.
size Default:
4096
Size (in bits) of the TLS/SSL key to generate
state
    Choices:
  • present ←
  • absent
Whether the private key should exist or not, taking action if the state is different from what is stated.
type
    Choices:
  • RSA ←
  • DSA
The algorithm used to generate the TLS/SSL private key
unsafe_writes
(added in 2.2)
    Choices:
  • no ←
  • yes
Normally this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, sometimes systems are configured or just broken in ways that prevent this. One example are docker mounted files, they cannot be updated atomically and can only be done in an unsafe manner.
This boolean option allows ansible to fall back to unsafe methods of updating files for those cases in which you do not have any other choice. Be aware that this is subject to race conditions and can lead to data corruption.

Examples

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

# Generate an OpenSSL private key with the default values (4096 bits, RSA)
# and a passphrase
- openssl_privatekey:
    path: /etc/ssl/private/ansible.com.pem
    passphrase: ansible
    cipher: aes256

# Generate an OpenSSL private key with a different size (2048 bits)
- openssl_privatekey:
    path: /etc/ssl/private/ansible.com.pem
    size: 2048

# Force regenerate an OpenSSL private key if it already exists
- openssl_privatekey:
    path: /etc/ssl/private/ansible.com.pem
    force: True

# Generate an OpenSSL private key with a different algorithm (DSA)
- openssl_privatekey:
    path: /etc/ssl/private/ansible.com.pem
    type: DSA

Return Values

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

Key Returned Description
filename
string
 changed or success
Path to the generated TLS/SSL private key file

Sample:
/etc/ssl/private/ansible.com.pem
fingerprint
dict
 changed or success
The fingerprint of the public key. Fingerprint will be generated for each hashlib.algorithms available. Requires PyOpenSSL >= 16.0 for meaningful output.

Sample:
{'sha1': '51:cc:7c:68:5d:eb:41:43:88:7e:1a:ae:c7:f8:24:72:ee:71:f6:10', 'sha384': '85:39:50:4e:de:d9:19:33:40:70:ae:10:ab:59:24:19:51:c3:a2:e4:0b:1c:b1:6e:dd:b3:0c:d9:9e:6a:46:af:da:18:f8:ef:ae:2e:c0:9a:75:2c:9b:b3:0f:3a:5f:3d', 'sha224': 'b1:19:a6:6c:14:ac:33:1d:ed:18:50:d3:06:5c:b2:32:91:f1:f1:52:8c:cb:d5:75:e9:f5:9b:46', 'sha256': '41:ab:c7:cb:d5:5f:30:60:46:99:ac:d4:00:70:cf:a1:76:4f:24:5d:10:24:57:5d:51:6e:09:97:df:2f:de:c7', 'sha512': 'fd:ed:5e:39:48:5f:9f:fe:7f:25:06:3f:79:08:cd:ee:a5:e7:b3:3d:13:82:87:1f:84:e1:f5:c7:28:77:53:94:86:56:38:69:f0:d9:35:22:01:1e:a6:60:...:0f:9b', 'md5': '84:75:71:72:8d:04:b5:6c:4d:37:6d:66:83:f5:4c:29'}

Size (in bits) of the TLS/SSL private key

Sample:
4096
type
string
 changed or success
Algorithm used to generate the TLS/SSL private key

Status

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
