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
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.
= operator is assumed as default, otherwise + or - operators need to be included in the string.

aliases: attr
cipher
-
added in 2.4
The cipher to encrypt the private key. (Valid values can be found by running `openssl list -cipher-algorithms` or `openssl list-cipher-algorithms`, depending on your OpenSSL version.)
force
boolean
    Choices:
  • no ←
  • yes
Should the key be regenerated even if it already exists
group
-
Name of the group that should own the file/directory, as would be fed to chown.
mode
-
Mode the file or directory should be. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number. Giving Ansible a number without following one of these rules will end up with a decimal number which will 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
-
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
-
Role part of SELinux file context, _default feature works as for seuser.
setype
-
Type part of SELinux file context, _default feature works as for seuser.
seuser
-
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
boolean
added in 2.2
    Choices:
  • no ←
  • yes
By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner.
This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes). IMPORTANT! Unsafe writes are 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
dictionary
 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:
{'md5': '84:75:71:72:8d:04:b5:6c:4d:37:6d:66:83:f5:4c:29', 'sha1': '51:cc:7c:68:5d:eb:41:43:88:7e:1a:ae:c7:f8:24:72:ee:71:f6:10', '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', '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', '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'}
