I did it now exactly as described. No import!
I tried with de- and reinstallation, but again the same: the import command is not working. Could it be a Vista problem?

I don't think so but I'm suspecting a codepage issue. Is your OS in English?

No its German.

Another point: I would prefer to import my own keys in offline mode. Thats how I did it with the btcurious build.

OK you're lucky, I couldn't manage to sleep so I spent all night working
on a special build of release 0.49b that finally includes a console. Smiley

Please download and try it from:
 http://win-electrum.googlecode.com/files/elec049b3.exe
 SHA-1: 6f1a8f787b76c9544399fdaa62e4d92788a174d7
 VirusTotal report: here

Notes:
To access the console: just hold down the SHIFT key while launching electrum.
Also, when typing commands, enclose electrum with parentheses (as shown in the example screenshot)

I'm not sure it will work for you right away, but at least you should get some more detailed error messages if it doesn't. Don't hesitate to report any errors.

Hi,

For the same reasons that you made this post, I just created a small program that generates bitcoin addresses and saves the keypair as an encrypted wallet file. It's basically a tool for the overly paranoid, since it doesn't create any unencrypted intermediate files and doesn't require the full bitcoin client just to generate an address. It also generates just 1 address, so it's impossible for somebody to steal your keys from an "old backup".

https://github.com/vegard/mkbtcaddr

Disclaimer: There is no warranty, etc., and I am not responsible if something goes wrong, etc.

I've tested it myself and it worked for me, but please scrutinise the source code before using it.


Vegard

Did some one tried this program using ubuntu live CD?

I find instructions rather a bit confusing which caused asking questions.

Do dependencies and programs mentioned already on ubuntu CD?
It would be great to how perform what being mentioned via gui!

I would think a truecrypt container and an encrypted .dat file should be enough to prevent any thief who at least does not have physical access to your computer.

How important is it to encrypt your wallet if you will only be using it for small transactions? Putting money in then immediately spending it?

well it's not so important if you receive small amounts but if you deal with large trades or store your btc for a long time its very important to keep this dates in a secure way.

i recommend that you should try at least this secure methods and after that decide if you want to go with the non secure way

Is this solution secure enough?

Create new virtual PC, put there some linux (Mint/Ubuntu/whatever) a install bitcoin client. Run it only few times a month just to sync with network (or made some payments). Most of the time have this whole virtual PC stored on HDD and/or external memory. I guess the trojans aren't clever enough to mount virtual disk file and steal from wallet saved on that virtual disk, or are they?

I'dn't be surprised if there were trojans capable of this.

there is no trojan to support external installation on hdd flash etc, but if the trojan has remote control your pc could be used as a port something like teamviewer but with hidden install.
