im working on a p2p file transfer app. at the moment its a close-source webapp, but i hope to work towards some selfhosted options as seen on my other projects.

the storage is local-only from your browser/device. so like "the cloud", but the cloud storage capacity is made up of your devices.

ive recently updated the landing page and i hope ive got it as simple as possible to transfer a file from one device to another.

im looking for feedback on the experience.

(Note 1: its still a work in progress. if there is an issue, you can usually refresh the browser and try again)

(Note 2: it seems important to mention: this app is not libre software. This needs more consideration to see if I can align to this. For information and open-source examples of the code in action, take a look at the docs and github for decentralized chat)

Nice! Can you tell me more about zero-knowledge encryption?

In my app I'm using asymmetric encryption to exchange a symmetric encryption key (Diffie-helman). I'm curious about other approaches for P2P authentication.

it means exactly this, the server hasn't any knowledge about your uploaded files or encrytion key. It's very save, but not really P2P, because of an server in the middle where the files are stored until download. Real P2P is eg, Croc, which transfer files direct from one PC to the other, without any server in the middle, you send an link which pointed direct to the files in your PC. The advantage is that you have anytime full control over the files and with this no limits on filesizes, but maybe a drawback is, that downloads are only possible, when your PC is online, on the other hand, this permits also to interrupt downloads, simply going offline, (it's FOSS)
