Show HN: A file server for Android, end-to-end encryption, web access Recently I’ve been playing with an idea of a file server on my Android phone, with a web browser access. I wanted to replace: – AirDroid – sending files to my own PC or laptop. – ShareIt – sending big files over the local network to my family devices. – Dropbox – sharing select files with other people over the Internet. Requirements I had in mind: – end-to-end encryption, no sign ups, no accounts, no passwords – local connection if devices are on the same network – asynchronous access, server should work seamlessly in the background This week I finally managed to stitch the pieces together and get something usable and useful. I now have full access to my phone on my laptop browser, I can share files with a link without uploading to the cloud, and the local network is used whenever possible. The file server app is on the PlayStore[1], web-client is here[2], and you can check out the roadmap[3]. Shoutouts to these great tools that made it possible: – libsodium[4], and it’s JS version, are used for the end-to-end encryption – StreamSaver.js[5], to save large files from a non-HTTP transport without buffering it in RAM. Had to patch it to add back pressure when the download is paused. Current limitations: – p2p only works on local networks, wait until WebRTC transport is implemented in the server – when downloading several files, a Zip is generated, with a 4Gb size limit, wait until I figure out the way to fix this. With a single file, it’s downloaded in plain and without limits.
