In today’s internet era, there are so many service out there that offer file sharing feature. On my own personal experience, I like to send file using messenger application like whatsapp, telegram, and fb messenger only for friends and family. Maybe because they are not secretly files hahaha.
But for the work use, one of the most commonly used file sharing is email or cloud-based such as dropbox. The services I mentioned above are private or public. What if we want it public but also private and encrypted (confidential) ?. You can try the latest services from Firefox/Mozilla Foundation named Firefox Send.
