short_description: Uses keytool to import/remove key from java keystore(cacerts)
description:
  - This is a wrapper module around keytool. Which can be used to import/remove
    certificates from a given java keystore.
options:
  cert_url:
    description:
      - Basic URL to fetch SSL certificate from. One of cert_url or cert_path is required to load certificate.
  cert_port:
    description:
      - Port to connect to URL. This will be used to create server URL:PORT
    default: 443
  cert_path:
    description:
      - Local path to load certificate from. One of cert_url or cert_path is required to load certificate.
  cert_alias:
    description:
      - Imported certificate alias.
  pkcs12_path:
    description:
      - Local path to load PKCS12 keystore from.
    version_added: "2.4"
  pkcs12_password:
    description:
      - Password for importing from PKCS12 keystore.
    default: ''
    version_added: "2.4"
  pkcs12_alias:
    description:
      - Alias in the PKCS12 keystore.
    default: 1
    version_added: "2.4"
  keystore_path:
    description:
      - Path to keystore.
  keystore_pass:
    description:
      - Keystore password.
    required: true
  keystore_create:
    description:
      - Create keystore if it doesn't exist
  executable:
    description:
      - Path to keytool binary if not used we search in PATH for it.
    default: keytool
  state:
    description:
      - Defines action which can be either certificate import or removal.
    choices: [ absent, present ]
    default: present
