A simple tool to transfer file over DNS. Unlike many others similar tools, no need for more than a command line or a small script for the client side. It is useful on a situation where you cannot even transfer a file and the clipboard is not shared.
To download a file, the server will split it in multiple chunks (default max size is 250) and send the corresponding chunk according to the TXT query (<numericalValue>.<domainName>.<tld>).
To be more stealthy the wait argument could be adjust to wait a specific time before answering the request. This will delay all the requests as the clients are not multi threading based. The parameter size could also be used to send less data for each response.
