module: ec2_win_password
short_description: gets the default administrator password for ec2 windows instances
description:
    - Gets the default administrator password from any EC2 Windows instance. The instance is referenced by its id (e.g. C(i-XXXXXXX)). This module
      has a dependency on python-boto.
version_added: "2.0"
author: "Rick Mendes (@rickmendes)"
options:
  instance_id:
    description:
      - The instance id to get the password data from.
    required: true
  key_file:
    description:
      - Path to the file containing the key pair used on the instance.
    required: true
  key_passphrase:
    version_added: "2.0"
    description:
      - The passphrase for the instance key pair. The key must use DES or 3DES encryption for this module to decrypt it. You can use openssl to
        convert your password protected keys if they do not use DES or 3DES. ex) C(openssl rsa -in current_key -out new_key -des3).
  wait:
    version_added: "2.0"
    description:
      - Whether or not to wait for the password to be available before returning.
    type: bool
    default: 'no'
  wait_timeout:
    version_added: "2.0"
    description:
      - Number of seconds to wait before giving up.
    default: 120

extends_documentation_fragment:
    - aws
    - ec2

requirements:
    - cryptography

notes:
    - As of Ansible 2.4, this module requires the python cryptography module rather than the
      older pycrypto module.
