Not much worse than legal vending, though. They say 80% of new businesses fail, right?

The hidden service is down. Strange timing that Freedom Hosting is also down. I don't remember FH ever being down this long.

Not providing a PGP key has nothing to do with the status of your order. The vendor could be busy or MIA for any number of reasons. After 4 days, you'll see the option to cancel your order, which won't affect your stats. If I were you, I would cancel. 4 days is more than enough for a a vendor to send out your order. Sometimes these things happened.

It happened on my first order. I got no response from the vendor and sent them a message. After 4 days I canceled. A month later they sent me a response saying they had been in jail for a month for unrelated reasons. Like I said, shit happens.

Those are just the people who bothered to report here, but it does show how high the turnover rate in SR vendors is. In a few months, half of them are gone.

Yep, Freedom Hosting has been down all day, along with the thousands of sites hosted on it.

Bridges are your first hop. Exit nodes are your last hop.

No, it won't work with any vanilla PGP programs that I know of. Even gpg has to be modified. I also did some benchmarks in a later post. It takes 34 times as long to decrypt a message that is encrypted with a 16K key compared to a 4K, so there's a noticeable 2+ second lag.

It is totally impractical, but I still have it as a novelty.

I tweaked the source code of my PGP software and now I'm rocking a 8192bit key.
It's a bit on the longish side, I know, but it's not paranoia if they're out to get you.

I got you beat with this 16384 bit bad boy. :)

Yes, if you are using Tor and visiting a clearnet site like whatismyipaddress.com, it will see your IP address as an exit node. What is the problem?

If you want to hide the fact that you are using Tor, you can point Tor Browser at a web proxy, like the ones on this list:

« on: August 01, 2013, 07:24 pm »
With SSL to the destination site you can have an end-to-end encrypted connection, but the destination site has to support SSL. In an age when you can get free SSL certifcates a la https://startssl.com and a few others, there's not much excuse though.

I would like something that could replace Tormail this year, and that relies on no central server. That is Torchat's greatest strength. Nobody can take it down or overwhelm the network / server, like what appears to happen to Tormail every time there's a database error. The trade off is that Torchat is a live messaging system. Both parties must be online at the same time. If it stored messages like BitMessage, that would be perfect.

Also, if they are anonymous users connecting over Tor, then why does it matter? Why not ask for the message directly?

How can you ask a server for a block of data without the server knowing which block it is?

The answer to that question is in several papers on Computational Single Server PIR (CPIR). Please let me know if you find one that will work for what I am trying to do, I will read it after you suggest it to me :D.

LOL. I thought the explanation with Alice and Carol was in response to my question, and I thought, that allows Carol to determine a message for her exists, but still, how does she ask the server for that message? I suppose she could ask for the whole database or a block of it that happens to include the message, so there's some plausible deniability.

Also, I want to know what Alice and Carol's secret is!
