What happens if I have a wallet, receive a payment on the first address and send one, then someone sends me a payment to the first address? Is this payment compromised in any way?

I am curious that if someone else has your wallet.dat's copy too, can they bruteforce it and get all the cash?

If someone has your wallet.dat, they already have your private keys and have no need to bruteforce.  Look up public-key encryption if that doesn't make sense.

No, it is not compromised. It wouldn't be a very good system if it were.

Not if the private keys are encrypted. In that case if a weak password was used someone could bruteforce it, sure.

Great read!

My toughbook has fingerprint read, smart card authentication and I'm in the process of getting them to work with the linux distro I am liveCDing. Also as the toughbook has had quite a 'tough' life the USB ports are fried so anyone who wants to gather info off it onto USB sticks end up with a blown up USB Stick Tongue

Fascinating read.

I think an additional security consideration is to diversify.
I currently spread my funds across a few online wallets and a few computers.
Generating the wallets on a liveCD and securing them over multiple .dat's is a great idea.

Great post. It sounds like you hate Windows. What do you think about a MAC, can i atleast leave an encrypted wallet on my computer. I believe if the wallet is encrypted to a high standard it should be uncrackable.

To the best of our knowledge it is... except by a keylogger. Smiley

This is good, I'd be so scared having more than like $50 in my bitcoin wallet. If I ever have larger amounts I will follow this guide, thanks Cheesy

Yup, I'm a windows cunt that was finally convinced to switch over to a Linux Live CD after realizing how easy it would be for a hacker to steal all my stuff.


And in the process I realized that Linux isn't so user unfriendly after all, and am starting to use it for any important data like checking bank accounts, etc.


Basically only boot up Windows to play games and graphic programs now.

Linux isn't all that user unfriendly eh?  I didn't study computer science in college so I'd be happy if I could just figure out how to get the Bitcoin program to function on my laptop with Linux Mint 11.  The program files are saved on my hard drive but they won't do anything.

Allright. Well if you don't trust the client from bitcoin.org or the ubuntu live CD, they are both open source, so you are able to compile it yourself.

Yes, and I also suggest, you read through the whole source-code that constitutes the entire Ubuntu distribution, just to make extra-sure Smiley

MBH: The whole point is to backup the entire disk, no? In that case, you still have to move your wallet.dat between the old CD and the new one. Besides, who guarantees that DSL will still be maintained a few years from now.

But if the encryption part was just meant for your wallet.dat, then yes, that's what I suggested. Just make sure, you use an encryption that will still be secure in a few years, otherwise, I'll steal it now (from your lame-ass cloud provider in case you use dropbox), keep it and decrypt it in 2018 with my quadruple ATI-over9000. Just a possible scenario. I prefer the more minimalistic physical security.

over9000 made me lol.
