Securely Send Large Files for Free Using Ruby with Firefox Send
We work with many Fintech startups and they are always looking for solutions to reduce out of pocket cost at the same time don’t want to compromise quality and security.
One of our Fintech clients is looking for sharing some confidential documents between users seamlessly using disposable links and track them within app built using Ruby on Rails. We evaluated a couple of free services and finally chosen Firefox Send.
Send is a free encrypted file transfer service that allows users to safely and simply share files from any browser. It uses end-to-end encryption to keep your data secure from the moment you share to the moment your file is opened
Now there are two ways you can share files using Share:
- Using Browser
- Using Command Line Utility
There is no API available as I am writing this. The easiest way to use the service from Ruby is to use command line library among the available options.
