/**
 * Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#getPasswordData(GetPasswordDataRequest) GetPasswordData operation}.
 * <p>
 * Retrieves the encrypted administrator password for an instance running
 * Windows.
 * </p>
 * <p>
 * The Windows password is generated at boot if the
 * <code>EC2Config</code> service plugin, <code>Ec2SetPassword</code> ,
 * is enabled. This usually only happens the first time an AMI is
 * launched, and then <code>Ec2SetPassword</code> is automatically
 * disabled. The password is not generated for rebundled AMIs unless
 * <code>Ec2SetPassword</code> is enabled before bundling.
 * </p>
 * <p>
 * The password is encrypted using the key pair that you specified when
 * you launched the instance. You must provide the corresponding key pair
 * file.
 * </p>
 * <p>
 * Password generation and encryption takes a few moments. We recommend
 * that you wait up to 15 minutes after launching an instance before
 * trying to retrieve the generated password.
 * </p>
