omg.. the client should automatically encrypt your wallet for you and make your life as easy as possible..

Christ, read the discussion, this already came up like a hundred times.

Well, BackTrack it (probably) is then, since my first choice was Ubuntu anyway. This is nice, since it might save some hassle with the encryption tools.

Would you be open to using the Gitian ( build method for the live CD?  It would allow users to validate the distribution by having it built and signed by multiple developers.  I can help with this.

Yes, I would be open to it. I didn't know about gitian, but I'm looking into it as we speak. If you want to help, my email is, though I'm busy until Tuesday, so my apologies if my replies won't be as swift as they should be.

The donation I'll be sending is pretty pathetic, but it's all I've got right now or I'd send more, sorry. Sad

Anyway yeah, please do, it'd be really appreciated. If you were to choose a Linux Distro I'd recommend BackTrack, as it's a distro designed spesifically for penetration testing, and therefore, security.

Don't apologize, you have my thanks. And as they say, if 50 people contribute just a little, you still get a lot of stuff done by the end of the day.

I have to check how well BackTrack does hardware detection, since usability is more important than penetration resistance. It won't be meant as a day-to-day OS. I'll clarify when I have the time. Thanks to everybody so far.

In case anyone here is interested in an all-in-one solution (this request came up frequently in the newbie discussion), I created a poll to see if there is any interest in having something like a simple, grandma-friendly tutorial and a prepackaged operating system, which would come in the form of a bitcoin-only USB-stick that allows safe transfers without the need of any technical affinity.

Head over there if you want to express your opinion about this: Poll for an easy security HOWTO (+ operating system)

THis all happend while the disk was mounted...

I understand the need for something really easy and secure, which is a legitimate concern if you're computer-illiterate but interested in bitcoin.

So, I decided to make a poll about providing an all-in-one solution: Poll for an easy security HOWTO. This would allow people like bitcoindude to use bitcoin safely with only very little prior knowledge.

Feel free to comment on it, but note that it would take me time (not _that_ much, a matter of a week or two) to give you this.

After writing the HOWTO on 100% security, a lot of you requested I do the same thing in a more comprehensible way, or that I provide a solution for absolute beginners.

So here's the deal: I have to know if you are serious enough, and if this is worth the trouble. Because if I do this, I'll do it properly, i.e I will test everything I write, there will be an easy guide for Linux, Mac and Windows and I will probably make a one-click solution, which will consist of a specific LiveCD, which already has bitcoin installed, and which will allow you to boot up a secure system and make transactions, without _any_ configuration necessary.

I did personalized LinuxCDs before, so this will definitely do-able. The result will be a solution for people with zero computer knowledge.

However, since this will take time and effort and since anybody can just click yes on the above poll, I'm asking for donations if you are _really_ serious about having an all-in-one solution. You don't have to send me anything at all, it's up to you.

Here's my hat: 16VD78R8nxqJGesE7E9KS6A8TikQQpKNm5

If you happen to find this proposal insulting (which is, that I don't want to spend a week making something that nobody uses), feel free to insult me in the comments below.

Can somebody PLEASE generate a "100% secure wallet FOR DUMMIES" step by step text document on this board. No downloads. Thatway, we older folks can feel safe in the bitcoin universe! This is critical in order to increase demand which will invariably lead to a higher price!!!

Also, once FOR DUMMIES version is posted, please vote on it. THANKS TO ALL OF YOU!

If there are enough requests for it, I'll write one. But have a look at the wiki in the meantime.

It's still early age for the BTC.

But if we all have to do this tricky stuff, the bitcoin will never thrive as a currency.

You geeky guys should give some solutions for the people not very familiar with these kind of complicated tech skill. Maybe backup\encrypt\import\export\ the wallet.dat function should be put into the future client software.

Bah, first of all, it's not that hard, second of all, you don't _have_ to do it, thirdly, it's only relevant if you handle larger sums. I hope you don't find putting your real money in a bank too geeky and/or hard.

I'll say it as often as I have to: Your suggestion would just lead to a false sense of security, and will be useless if the user doesn't know what he's doing. I'm sorry, but that's the reality of it: If you do dumb stuff, behave irresponsibly with large sums, no IT security in the WORLD will save you from the threat of being robbed.

So you, as a person who likes it the convenient way, you still have two options: 1. Use Linux. Jesus, at least for bitcoin. And the still, don't click on everything you find on the internet, watch your porn on another account and, ideally, ditch that fuckwad called adobe-flashplayer.
2. Do it as people do with banks: entrust a professional with your money. I'm sure as bitcoin will establish itself, services like that will pop up. Still: if you write down your password to that service somewhere, you're hopeless. And even if you behave like the smart person you are, there may still be risk involved as long as you don't understand the technical side of it. It's not that hard, really.

Read the guide in the wiki, it basically recommends setting up a safe account for bitcoin. It's secure enough while still being convenient to use _and_ easy to set up.

how about simply printing out the .dat file and storing it in a fireproof safe. at least then its long term safe storage of your wallet.

Sure, the idea already came up somewhere. But two things:
1. It would have to be shortened considerably, which is possible I think. Right now it would give you a few hundred pages.
2. Have fun typing it in when you want to use your coins. (So a few sheets of 2D barcodes might make more sense)

3. Tell this to a noobie and he will end up with a sheet of paper with the word "wallet.dat" printed on it. And he will then complain loudly to you if it doesn't allow him to access his bitcoins Smiley

when u boot from a live cd, how is it that you can install a copy of Bitcoin with a new wallet that doesn't touch RAM?  if it does, isn't that an opportunity for a trojan to detect your wallet?

Well of course it touches RAM, but the point is, that your liveCD is clean like a virgin, so there shouldn't be any chance for a trojan to interfere with your system.

Really? One needs to download and install a separate OS to have a safe wallet?
That is going to turn those people down who don't know about computers
I would have thought that the bitcoin community had come up with an easier alternative,
let alone making it safe to use bitcoins by default.
Well, I guess I just have to download Ubuntu, I hope thought that there will be more simple alternatives in the future.

Sure, there are simpler alternatives. See the wiki (link in the article) for another secure setup. My aim was to obtain 100% security, which is in no way necessary for everybody.

And yes, if you're using Windows for serious business, you really shouldn't. But that holds true in general. Oh and, I didn't say "install", just boot a liveCD from an USB-stick, its quite fast.

It is more of an accident that bitcoin got so much media attention in version 0.3.2x - the number should explain everything.

Well, to be fair, that's actually the traditional way opensource programs usually do their numbering: total understatement. If it was a commercial program, you bet they would be at least at version 3 right now.
113  Other / Beginners & Help / Re: HOWTO: create a 100% secure wallet on: June 16, 2011, 10:31:20 AM
Can't the wallet.dat be encrypted already? (password when starting the bitcoin client...)

As has been said elsewhere, this wouldn't work, since the client has to somehow decrypt the file in order to use it. Decryption => a decrypted copy is stored in RAM => a clever program can find and copy it.

So this would be rather dangerous, since it would give users a false sense of security, prompting them to be even more careless. I know lots of users are whining right now and blaming the devs for not including encryption, but this is simply the truth of the matter.
114  Other / Beginners & Help / Re: HOWTO: create a 100% secure wallet on: June 16, 2011, 07:18:01 AM
Alex, I think you're wrong. You can send anything you want to a given bitcoin address, I mean otherwise the network would have to refuse a certain transaction. That's just not the case. Maybe you're confusing this with how the client behaves?

Let me say this again: You may do the following: put your wallet.dat in a safe, delete/shred any local copies, use a different account to transfer coins to it and do this as long as you please. Nothing will make it generate new addresses, that's the job of the client. Your wallet is just the _key_ to a number of addresses.

And true, you can and should use, so you'll have an oversight over what's happening on your safety account.
115  Bitcoin / Bitcoin Discussion / Re: HOWTO: create a 100% secure wallet on: June 16, 2011, 07:12:27 AM
But in theory the client could make the transaction offline by writing it to a transaction file. You could then transport that file to an online computer and send it to the network from there.

Ooh, that would be tits!
116  Other / Beginners & Help / Re: Correction: on: June 16, 2011, 06:22:10 AM
There appears to be a little more to the wallet's key handling than I had thought.  There are a couple posts in another thread that make it sound like every time you send BitCoin from your wallet, the client uses a new "hidden" receiving address for any remainder.

If I send you 4btc but my only coin is worth 5btc, 1btc is sent back to me at a new 'change' address.

So it sounds like receiving BitCoin does not require either usage or backup of your wallet (it can stay offline and hidden in a safe), but every so many times of sending BitCoin (~100?) will require replacing the backup due to new "change" keys.

Nope, that would be strange and impractical. And probably not even possible to implement. So transfer as many coins as you'd like to your preferred address, nothing is going to go wrong.

The whole thing with the generation of new addresses is simply a mechanism in the _client_ in order to gain further anonymity.

And thanks a million everybody for answering questions!

I have a question, if someone happens to know, and sorry if this was already asked.

Can someone sniff both your public and private key off the network? Can someone explain technically if this is possible?

What I mean is, even if your computer has NO malware on it, is it possible for someone to intercept the keys and then use them?

No. Interception is impossible, simply because the whole concept of a private key implies that it will _never_ have to leave your PC. It's just used to generate a signature if you will, which then "proves" to the network that you are allowed to make a transaction from address X.

aral: So you're saying burning CDs is too tedious, better buy a netbook and use that as medium? And do you specifically require a crappy one?  Roll Eyes

Why are you taking the piss?  I have just made your idea way more convenient.   Undecided

Instead of booting up off a liveCD (which IS slow) then installing bitcoin and waiting for the download, you can just fire up the netbook. 

You can make a script that burns an encrypted wallet copy as well, do whatever you want, it's waiting there for next time you need it.

When you've finished the transaction you just stow the netbook in the safe again.  If I had 25k BTC I would probably do this.  I think it makes a whole lot of sense.

Don't sweat, I like taking the piss. Just yanking your chain... Smiley

My initial point was, that you don't need to access your wallet.dat in order to transfer funds to it, so as long as you're in piggybank-mode, a tiny SDcard in a safe seems the least error-prone way.

But you're right of course. If you can store a netbook safely somewhere and trust its hardware will remain intact it'll work. Just never, ever install any programs in userspace. And of course, see that you never use sudo for anything you're not 100% sure about. So thanks for your contribution (Ugh, that's me being nice, I hate myself already).

How does a keylogger get installed on a live cd?

See my link in the guide. Not only are there physical keyloggers which you usually put between the keyboard an the USB-port, but there are ways to remotely monitor what you're typing.
