passwordcheck for rclone config files

In https://github.com/rclone/rclone/issues/4783 a security issue was found which meant that passwords generated by "rclone config" might be insecure.

This program checks your rclone config file for any of those passwords.

Installation

Download the relevant zip file for your OS and architecture from here:

• https://github.com/rclone/passwordcheck/releases

Unpack the zip archive - use unzip archive.zip on Linux/macOS - use Explorer on Windows.

Open a terminal and change directory to the place you unpacked the zip file.

First find where your rclone config file is.

 rclone config file
Configuration file is stored at:
/home/USER/.rclone.conf

Now run the utility with this as an argument

./passwordcheck /home/USER/.rclone.conf

Note that it may take 10 minutes or more to run. At the end it will print a report showing any insecure passwords found.

For example:

$ ./passwordcheck ~/.rclone.conf

2020/11/19 14:01:49 found 54 passwords generated by rclone config which need checking

NB don't make public any of the obscured passwords that rclone prints - these can easily be reversed into the actual password. The ones show here are for demonstration purposes.
