Show HN: Mirall – Secure large (terabyte) file transfer. No cloud. No middleman

For whatever reason it has become really hard to transfer very large files with the modern Internet. Usually you end up with paying some cloud provider to store the files so that somebody else can download them. But this is not how it has to be. I've been building Mirall to actually that problem. Mirall is a peer-to-peer application that enables the secure transfer of very large files, hundreds of gigabytes or even terabytes between two computers without any third-party servers or middlemen.

The idea to build Mirall was born at the Mallorca Film Festival. Companies and individuals in the movie industry often have the challenge to transfer large data files during the post production phase of a movie while large production studios often offer their own file transfer solutions. Smaller companies or individuals are often relying on consumer grade third party services, usually this is not allowed because of the potential of data leaks. Somehow it has become a complex problem to transfer large files over the internet. I overheard conversations where this was discussed and thought to myself that I might be able to solve that problem. Having used the Keet app and with some basic understanding of what the Pear framework is able to offer from a capability perspective, I thought I might give it a try.

Over the past four months I've been busy building this app with a high focus on ease of use and security. Now it is out there. The app is open source and free to download and use. I hope it solves a problem for many of you out there. Please give it a try and let me know if it works for you or where to improve.
