perguth / peertransfer

:package: • Send a file p2p and e2e encrypted in your browser using WebRTC.

Peertransfer

In-browser secure peer-to-peer filetransfer in three simple steps:

1. Select the file you want to send.
2. Open the generated link on other PCs.
3. Download over a direct, authenticated and end-to-end encrypted line.

Thus the file will only be available for download as long as the sender keeps his browser tab open.

Features

• Data is sent directly peer-to-peer.
• Data is transferred using end-to-end encryption (due to WebRTC).
• The messages that are relayed by a server to initiate the p2p WebRTC connections are encrypted (to protect against IP leakages and man-in-the-middle attacks while initiating WebRTC).

Install

A hosted instance of Peertransfer is available at https://perguth.github.io/peertransfer/

git clone https://github.com/pguth/peertransfer.git
cd peertransfer
export NODE_ENV=production
npm install
npm start
# You can also set HUB_URLS to a comma separated list of `signalhub` URLs

peertransfer's Issues

Back button does not close connection.

An in-range update of crypto-js is breaking the build 🚨

The dependency crypto-js was updated from 3.1.9-1 to 3.2.0.

🚨 View failing branch.

This version is covered by your current version range and after updating it in your project the build failed.

crypto-js is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.

Status Details

• ❌ continuous-integration/travis-ci/push: The Travis CI build could not complete due to an error (Details).

FAQ and help

There is a collection of frequently asked questions. If those don’t help, you can always ask the humans behind Greenkeeper.

Your Greenkeeper Bot 🌴

If first transfer dies all subsequent transfers fail

The tool caches while sending the first copy. If the transfer dies the cache never finishes and subsequent transfers get only already cached chunks.

Send blobs instead of dataURLs!

http://peerjs.com/docs/#dataconnection

Download never finishes

Last package gets stuck?!

Encrypt once, send multiple times (=store temporarily for one session)

• Check if enough temporary storage is available.
• Read in chunks, encrypt save as blob
• Sendable in blobs or convert to dataURL?

Make code resilient against out of order packages

Receving chunk #1088 of 1093
bundle.js:57 Receving chunk #1093 of 1093
bundle.js:255 'webkitURL' is deprecated. Please use 'URL' instead.

bundle.js:57 Receving chunk #1092 of 1093

Download starts before file transfer finishes.

multiple files

can you add the possibility to add multiple files (zip them for example like takeafile.com) ?

Read file into localStorage

Persist file title

Read in chunks (to allow for bigger files)

Using the back button breaks the next file transfer w/o reload

Better do a reconnect and also get a new peerID on 'back'.

Only continue sending on regular `acks`; prevent sending with noone listening.

Display file title in URL?!

Set up own HTTPS enabled PeerJS server for gh-pages

https://github.com/peers/peerjs-server

• Enrichten
• SSL cert installieren

Optimize jQuery calls.

Rename project.

Problem loading page

[email protected] start /root/peertransfer

[[ $NODE_EVN = production ]] && npm run prod || npm run dev

sh: 1: [[: not found

[email protected] dev /root/peertransfer

But cant connect to webpage

Find out good chunk size

Maybe vary chunk_size and check performance...

Failing CI

https://travis-ci.org/perguth/peertransfer/builds/481908576#L492

It seems the provided token is not valid anymore.

Add opacity transition (fade in/out) on "Downloading Peer" bars.

At least include Standard JS style

https://github.com/feross/standard

Back button does not close connection.

Error handling

• "Could not connect. Retry."
• If HTTPS for broker is disabled give alarm when user is trying to use HTTPS.

Give more status feedback (progress bars, download counter)

When several peers connect simultaneously only the most recent peer receives data.

Document usage

How do I actually run the project?
I have successfully cloned the project.
But I don't see any server.js file to run a server for file transfer.

Stuck on Getting ready

signalhub.perguth.de is down or something?
sharedrop.io is down, this is down, everything is down?

Save in chunks (to allow for bigger files)

• Query storage available
• React accordingly: Temporary or persistent storage

Source

Retry link broken.

When several peers connect simultaneously only the most recent peer receives data.

Stick to JS Standard style

Transfer dies over long distances/bad connections

I guess it's because the sending side closes the connection after it thinks it has finished.

An `#` added before a file is selected breaks the app.

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because it uses your CI build statuses to figure out when to notify you about breaking changes.

Since we didn’t receive a CI status on the greenkeeper/initial branch, it’s possible that you don’t have CI set up yet. We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

If you have already set up a CI for this repository, you might need to check how it’s configured. Make sure it is set to run on all new branches. If you don’t want it to run on absolutely every branch, you can whitelist branches starting with greenkeeper/.

Once you have installed and configured CI on this repository correctly, you’ll need to re-trigger Greenkeeper’s initial pull request. To do this, please delete the greenkeeper/initial branch in this repository, and then remove and re-add this repository to the Greenkeeper integration’s white list on Github. You'll find this list on your repo or organization’s settings page, under Installed GitHub Apps.

Enable mobile browsers

Authenticate incoming connection

Add WebRTC checker

Some browsers do not support WebRTC, so I hope that peertransfer can detect whether WebRTC is supported when loading a web page and remind users.

Write install guide.

Use `dataConnection.close()`.

http://peerjs.com/docs/#dataconnection

On back, clean enc-data cache or else subsequent transfers after using back fail!

File upload clickable before ready

Write a feature list.
