Description

This module allows one to (re)generate OpenSSL public keys from their private keys.

Keys are generated in PEM or OpenSSH format.

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 I(select_crypto_backend) option. When I(format) is C(OpenSSH), the C(cryptography) backend has to be used. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13."

Inputs

    
mode:
    description:
    - The permissions the resulting filesystem object should have.
    - For those used to I(/usr/bin/chmod) remember that modes are actually octal numbers.
      You must give Ansible enough information to parse them correctly. For consistent
      results, quote octal numbers (for example, V('644') or V('1777')) so Ansible receives
      a string and can do its own conversion from string into number. Adding a leading
      zero (for example, V(0755)) works sometimes, but can fail in loops and some other
      circumstances.
    - Giving Ansible a number without following either 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, V(u+rwx)
      or V(u=rw,g=r,o=r)).
    - If O(mode) is not specified and the destination filesystem object B(does not) exist,
      the default C(umask) on the system will be used when setting the mode for the newly
      created filesystem object.
    - If O(mode) is not specified and the destination filesystem object B(does) exist,
      the mode of the existing filesystem object will be used.
    - Specifying O(mode) is the best way to ensure filesystem objects are created with
      the correct permissions. See CVE-2020-1736 for further details.
    type: raw

path:
    description:
    - Name of the file in which the generated TLS/SSL public key will be written.
    required: true
    type: path

force:
    default: false
    description:
    - Should the key be regenerated even it it already exists.
    type: bool

group:
    description:
    - Name of the group that should own the filesystem object, as would be fed to I(chown).
    - When left unspecified, it uses the current group of the current user unless you
      are root, in which case it can preserve the previous ownership.
    type: str

owner:
    description:
    - Name of the user that should own the filesystem object, as would be fed to I(chown).
    - When left unspecified, it uses the current user unless you are root, in which case
      it can preserve the previous ownership.
    - Specifying a numeric username will be assumed to be a user ID and not a username.
      Avoid numeric usernames to avoid this confusion.
    type: str

state:
    choices:
    - absent
    - present
    default: present

      from what is stated.
    type: str

    type: str
    version_added: '2.4'
    version_added_collection: ansible.builtin

serole:
    description:
    - The role part of the SELinux filesystem object context.
    - When set to V(_default), it will use the C(role) portion of the policy if available.
    type: str

setype:

seuser:
    description:
    - The user part of the SELinux filesystem object context.
    - By default it uses the V(system) policy, where applicable.
    - When set to V(_default), it will use the C(user) portion of the policy if available.
    type: str

    description:
    - The level part of the SELinux filesystem object context.
    - This is the MLS/MCS attribute, sometimes known as the C(range).
    - When set to V(_default), it will use the C(level) portion of the policy if available.
    type: str

attributes:
    aliases:
    - attr
    description:
    - The attributes the resulting filesystem object should have.
    - To get supported flags look at the man page for I(chattr) on the target system.
    - This string should contain the attributes in the same order as the one displayed
      by I(lsattr).
    - The C(=) operator is assumed as default, otherwise C(+) or C(-) operators need to
      be included in the string.
    type: str
    version_added: '2.3'
    version_added_collection: ansible.builtin

unsafe_writes:
    default: false
    description:
    - Influence when to use atomic operation to prevent data corruption or inconsistent
      reads from the target filesystem object.
    - By default this module uses atomic operations to prevent data corruption or inconsistent
      reads from the target filesystem objects, but sometimes systems are configured or
      just broken in ways that prevent this. One example is docker mounted filesystem
      objects, 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 filesystem
      objects 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.

      and falls back to C(pyopenssl).

      library.
