How would this compare to DropBox and other alternatives?

Well with Dropbox you know that the government can request any data presently or previously in your folders. With btsync it doesn't seem to be so easy because data isn't stored centralized, but there are some potential leaks. Still better than Dropbox.

What's wrong with using http instead of https on the localhost web server?

I assume you refer to this:

> [LOW] confirmed: When registering, http traffic for creating new user on loopback http://127.0.0.1:8888

And I wonder the same. Didn't really get that one, but yeah you may be right that they mean it should be https. I guess the risk is when an application can monitor loopback traffic, but you can only do that with special permissions or if you're root. The former case is exceptional, in the latter case you're pwned anyway and your keystrokes aren't safe either. So yeah, I don't know. Https might do a little bit extra... but I don't know.

So if I understand this right, there's probably a backdoor in it? Honestly though, I doubt that you can keep the NSA and FBI out of your system. If they want in, they'll get in, and there's nothing* you can do about it.

Having said that, we do need these kinds of solutions without the back doors. Why aren't any software developers from countries where mandatory backdoors aren't a thing building stuff like BTSync? And does anyone know which countries those are? For example, i live in Belgium. Were I to build such a thing, would someone show up on my doorstep and force me to backdoor it?

(*) nothing that is reasonable, only paranoia and extreme lengths will suffice.

I don't use it for sensitive information BUT for my needs this is a great solution that is MUCH better then a cloud based file system. I have my media files for my Phone just BTSync them when I need them and it works like a charm. Also works great for syncing my photos between my computers like photos.

It would be perfect if only they open-sourced it.

From the "Conclusions" section: > Change of sharing paradigm that introduced this vulnerability happened after the first releases. This may be the result of NSL (National Security Letters, from US Government to businesses to pressure them in giving out the keys or introducing vulnerabilities to compromise previously secure systems) that could have been received by BitTorrent Inc and/or developers. IF that's true, the…

I'm no security expert, but when I saw they did that whole "easier sharing" thing over e-mail that raised a major red flag for me. It seemed quite obvious that many of the previously secure systems would now be broken by that insecure e-mail sharing system.

There's Syncthing, but I'm not a big fan of the whole "server"-like interface. They've improved it recently, but it still seems quite non-consumer-friendly.

I disagree... My guess is that if you choose to enable features like that you're most likely opening a door, but if you don't it won't compromise anything.

At least, that's how any competent developer would code it.
