Great guide.
i agree with notion to encrypt walet.dat when storing it.
also the length of password is critical. so mare at least 13 character pw that includes letters numbers and special chars. if you think that is too difficult to remmember - it is cryptologically as safe if your pwis like this: SoM3pW55$$$$$ as long as it is a secret which char was repeated at end....

Yes, both of you have a point I thought about as well: You still have to use the bitcoin client downloaded from the official site, sou you have to trust that thing unconditionally. And yes, you have to trust the liveCD

Of course, someone could trick you into downloading the wrong software (DNS redirect?). But there's a point where a certain level of paranoia is kind of exaggerated. You could of course always write your own client Smiley

I think it makes sense to trust both the Ubuntu LiveCD as well as the client from bitcoin.org for now.

yes i was thinking same

0) Why does that happen (the change itself) if I'm sending the exact amount I want to send?
1) As I understand, the change address is created and saved in the wallet.dat file but doesn't show up in the User Interface (UI). So how do I claim my money?

Sorry, I just have to ask:  Why did you start your numbering at 0?
Tongue

Because everything starts from zero :p

0 is so important that it is the only number that had to be invented! 8^)

Hi Everyone,

Security seems to be a bit of a problem for Windows users- we have an existing product that is easily adaptable for this use!

We have come up with a solution using our ‘DiscreetKey’ product – all it requires is an additional download on your part.
Here’s how it would work after the initial set up:

•   Insert your DiscreetKey into your computer (via the USB port)
•   A padlock icon will appear on your screen
•   Simple drop the wallet file onto the padlock icon
•   Your wallet is now encrypted and the BitCoin application starts.

You can now use the BitCoin program as usual. When you exit the program your wallet is automatically re-encrypted. The wallet file encryption is highly secure (256 Bit AES with one-time password) and can be backed up (via e-mail, cloud computing services, etc.).

We expect the final product will cost around 3 BitCoins – this includes the physical DiscreetKey and KeyMaker as described on our website http://datadiscretion.com/products/discreetkey

What do you think?

We would appreciate any ideas!

What would be interesting is if anybody has a peer reviewed paper of a competitive crypto currency that has various improvements... Personally, I'd like to see a method to eliminate the initial 'gold rush' to reduce valuation volatility in the beginning phase.... and a method for automatic backups of wallets between peers with some kind of strong of encryption of the primary private key using a passphrase.  Maybe there would be a time-to-live set for the backup copy on any given peer, like 2 hours, and then the backup would roll to a new random peer and get purged from the original peer with a handoff transaction record stored in those peers involved, the log would live for a set time, like 3 weeks...  Then a way to poll the network for a count of available copies of backup keys, where certain nodes could delete a few backups if extra nodes respond, request creation of more backups if the count is getting low... blah blah... I don't know... seems like the currency might be better if people could trust that their money won't get erased when their hard drive goes bad without having to trust any one person with their key, and the rolling backup might allow a mechanism to track down anybody dedicated enough to crack a passphrase. Also, I'm not sure what method exists to prevent a node from a DoS attack on all peers, but hopefully the system is/could be really good at identifying malicious activity and temporarily banning the IP address used at the source.

Anyhow, I don't know what the heck I'm talking about, so I'm here to learn and BS until I figure out answers to these questions.

But this is something I'm pretty sure is an easily fixed problem that might be worthwhile for a non-newbie to post on the forums...  Why isn't there really good password complexity requirement so that the wallet.dat file could be stored on your hard drive in a safer manner?  When I typed a password into the system after installing BitCoin, I wasn't required to enter a very complex password. People hate the need to create a really complex password, but without FORCING people to do so, there will inevitably be a little devaluation of the system.  Again, maybe I just don't know what I'm talking about, so I will shut up now. =)

This is not 100% safe. Probably 99%. You forget about the BIOS,MBR and Viruses that can Infect your Graphics Bios. These will Infect your CD/USB distro after reboot.

If you're worried about those writing to your sd-card, then you can set it to read-only when you don't need to write to it. If you're worried about it reading data on the card...any virus could do that already (so if you're infected, you're SOL). If you have one of those on your computer, then you're in pretty bad shape already and I don't know how to help you.  Undecided

I downloaded BitCoin and installed the program, and it shows up in my C;/Program Files, but no where in there is a wallet.dat file. Does anyone know why?
