Tell me more about how this solves security problems? (I'm asking, I don't already have an opinion). Why can I trust this service with (say) a zip file full of source code?

It forms an encrypted direct connection between the sender and the receiver. The data never touches anyone else's server and is encrypted the entire trip. Everyone feel free to run a tcpdump dump of the traffic if you want confirmation thats not from the guy who made the service.

Really? You wrote custom crypto for this? Or do you use an SSL connection?

I wouldn't have thought to ask that. My original concern was: how do you assure someone like me that an attacker can't redirect files to other locations?

How different Sendoid is from Tonido?( http://www.tonido.com ) With Tonido you can right click any file or folder and it will create an URL for the resource. You can share the URL with anybody for download. There is no limit on file size, no uploading - completely private and secure.

Can't find their send file immediately from the browser button? I don't think my dad's gonna be able to use it without that.

Interesting. How do you punch through NATs and firewalls? If you're doing it with p2p proxies, how do you do authentication and avoid mitm attacks?

Neat technology, but I'm a bit worried about having to leave the browser window open before/during the transfer. I accidentally close tabs all the time, I wouldn't want to do that in the middle of a long transfer. I'm going to give the service a shot for a few weeks though, maybe that will turn out to be a non-issue in practice.

Thats what the helper app is for! Sits outside the browser and lets you send and receive using the same technology without having to worry about the browser thing. Will do resume and everything. Still just as easy to use too.

Sorry, but I can't find a link to the app. Do I have to install the browser version first?

The protection against redirection is inherent in the underlying peer-to-peer media streaming technology we built on top of (RTMFP), as is the crypto. Going off your profile you seem to be a security researcher type. Would love to discuss things further with you offband. Feel free to email me directly, email is in my profile.

Missing from the article (and the linked summary of other sites that do this) is letscrate.com, which does it so well that I'm not even interested in looking at sendoid. It's dead easy, and my clients understand and remember the name after I say it once.

Thanks for the mention! A lazy link because I'll never miss a chance to shameless plug: http://letscrate.com/ Excited to check out Sendoid though.

So good you guys are blocked at the local library.

I see it as validation and a compliment, well done.

I'd have done the same thing. And yes, I upvoted your shameless plug. ;)

The install button is the helper app! The in browser part should work immediately with no need to install any other software.

I don't believe that your email is there. I may take a whack at it later this week (we're launching a product and I'm pretty busy, but I do love me some custom crypto protocol.)

Awesome service! One major request: Please create an API. So many startups/services need a good way to upload large files efficiently. It takes a lot of effort to create an file upload feature that works and provides a good UX across browsers/platforms. We would use it for Mugasha (artists upload large audi files) and would pay for it.

Check out Crate's API? http://letscrate.com/api
