community.crypto.openssl_privatekey – Generate OpenSSL private keys
community.crypto.openssl_privatekey – Generate OpenSSL private keys
Note
This plugin is part of the community.crypto collection (version 1.4.0).
To install it use: ansible-galaxy collection install community.crypto
.
To use it in a playbook, specify: community.crypto.openssl_privatekey
.
Synopsis
- Keys are generated in PEM format.
- One can generate RSA, DSA, ECC or EdDSA private keys.
- Please note that the module regenerates private keys if they don’t match the module’s options. In particular, if you provide another passphrase (or specify none), change the keysize, etc., the private key will be regenerated. If you are concerned that this could overwrite your private key, consider using the backup option.
- The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. This can be overridden with the select_crypto_backend option. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in community.crypto 2.0.0.
- This module allows one to (re)generate OpenSSL private keys.
Requirements
The below requirements are needed on the host that executes this module.
- Either cryptography >= 1.2.3 (older versions might work as well)
- Or pyOpenSSL
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
attributes string added in 2.3 of ansible.builtin |
The attributes the resulting 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. The

Create a backup file including a timestamp so you can get the original private key back if you overwrote it with a new one by accident. |
cipher string |
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.) When using the | |

Should the key be regenerated even if it already exists. |
format string added in 1.0.0 of community.crypto |
|
Determines which format the private key is written in. By default, PKCS1 (traditional OpenSSL format) is used for all keys which support it. Please note that not every key can be exported in any format. The value Note that if the format for an existing private key mismatches, the key is *regenerated* by default. To change this behavior, use the format_mismatch option. The format option is only supported by the |
format_mismatch string added in 1.0.0 of community.crypto |
|
Determines behavior of the module if the format of a private key does not match the expected format, but all other parameters are as expected. If set to If set to Only supported by the |
group string |
Name of the group that should own the file/directory, as would be fed to chown. | |
mode raw |
The permissions the resulting file or directory should have. 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 Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, If If Specifying | |
owner string |
Name of the user that should own the file/directory, as would be fed to chown. | |
passphrase string |
The passphrase for the private key. | |
path path / required |
Name of the file in which the generated TLS/SSL private key will be written. It will have | |
regenerate string added in 1.0.0 of community.crypto |
|
Allows to configure in which situations the module is allowed to regenerate private keys. The module will always generate a new key if the destination file does not exist. By default, the key will be regenerated when it doesn't match the module's options, except when the key cannot be read or the passphrase does not match. Please note that this changed for Ansible 2.10. For Ansible 2.9, the behavior was as if If set to If set to If set to If set to If set to Note that if format_mismatch is set to |
return_content boolean added in 1.0.0 of community.crypto |
|
If set to Note that especially if the private key is not encrypted, you have to make sure that the returned value is treated appropriately and not accidentally written to logs etc.! Use with care! Use Ansible's no_log task option to avoid the output being shown. See also https://docs.ansible.com/ansible/latest/reference_appendices/faq.html#how-do-i-keep-secret-data-in-my-playbook. |
select_crypto_backend string |
|
Determines which crypto backend to use. The default choice is If set to If set to Please note that the |
selevel string |
The level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the When set to | |

|
Whether the private key should exist or not, taking action if the state is different from what is stated. |

|
The algorithm used to generate the TLS/SSL private key. Note that |
unsafe_writes boolean added in 2.2 of ansible.builtin |
|
Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file. 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. |
