openssl_privatekey – Generate OpenSSL private keys
openssl_privatekey – Generate OpenSSL private keys
New in version 2.3.
Synopsis
- This module allows one to (re)generate OpenSSL private keys.
- One can generate RSA), DSA, ECC or EdDSA private keys.
- Keys are generated in PEM format.
- 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.”
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 |
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
| |
backup boolean added in 2.8 |
|
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 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.) When using the | |
curve string added in 2.8 |
|
Note that not all curves are supported by all versions of For maximal interoperability, We use the curve names as defined in the IANA registry for TLS. |
force boolean |
|
Should the key be regenerated even if it already exists. |
group string |
Name of the group that should own the file/directory, as would be fed to chown. | |
mode string |
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, | |
owner string |
Name of the user that should own the file/directory, as would be fed to chown. | |
passphrase string added in 2.4 |
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 0600 mode. | |
select_crypto_backend string added in 2.8 |
|
Determines which crypto backend to use. The default choice is If set to If set to |
selevel string |
Default: "s0" |
The level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the When set to |
serole string |
The role part of the SELinux file context. When set to | |
setype string |
The type part of the SELinux file context. When set to | |
seuser string |
The user part of the SELinux file context. By default it uses the When set to | |
size integer |
Default: 4096 |
Size (in bits) of the TLS/SSL key to generate. |
state string |
|
Whether the private key should exist or not, taking action if the state is different from what is stated. |
type string |
|
The algorithm used to generate the TLS/SSL private key. Note that |
unsafe_writes boolean added in 2.2 |
|
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. |
