Title: Security measure Post by: spazzdla on October 12, 2014, 03:18:52 AM Creation: Copy bitcoinaddress.org site to CD, run on offline computer, create encrypted addresses, print them to .xps and copy to cd, destory hard drive.
Removal: decrypt an address on offline computer, copy a private key to cd, destroy hard drive. Upload private key to a wallet. Effectiveness = 100%? Title: Re: Security measure Post by: chanz on October 12, 2014, 04:23:33 AM I did kinda the same thing but with bitaddress (https://bitcointalk.org/index.php?topic=43496.0) and yes i think what your are doing there is somewhat safe.

Hope so.. lol. Can't see how it would get taken.

You will want to create multiple backups of your private key. This is true for both quantity and type of backup.

I used a CD to move them off the offline HD so nothing could be copied from the HD but what I wanted. Then backed it up like a mad man.. I don't know if I am done backing up actually.. Kinda had some crazy plans to plant them around a large area in weather proof containers.... yaa.. LOL .. PROTECTION PROTECTION PROTECTION. Was going to go to factory direct to buy a but ton of CD's.

Title: Re: Security measure Post by: orsotheysaid on October 13, 2014, 12:32:10 PM Isn't this overkill? And why not just use Trezor, as mentioned above?? It keeps the master public key when disconnected, unless you click "forget device".
If you don't want the master public key exported you'll have to use another non-web wallet service like Electrum.

Can't you just: --> Disconnect from internet --> Boot from a live Ubuntu disc/USB --> Run a wallet like MultiBit, generate offline addresses --> Copy/write keys to DVD, print paper wallets --> Shut down the PC Title: Re: Security measure Post by: spazzdla on October 13, 2014, 01:40:27 PM Creation: Copy bitcoinaddress.org site to CD, run on offline computer, create encrypted addresses, print them to .xps and copy to cd, destory hard drive.

I'm not debating it's longer than it needs to be.. just curious about it's point of failures. As far as I can tell it is only the encryption pass.

Next time when NASA launches a rover to Moon or Mars, I will send my private keys with it to be planted there, just to be sure of being protected from any apocalypse.

Title: Re: Security measure Post by: aronnov on October 25, 2014, 04:01:37 PM seems too complicated to do to backup your wallet address, I think you only need to wear blockchain.info for your wallet, and let the wallet system that protects the security of your account and bitcoin ... ;D
Title: Re: Security measure Post by: btcguys on October 25, 2014, 04:34:04 PM Destroying hard drive seems a little expensive.
Try this: You will need two USB drives Disconnect all the internal drives create one live Ubuntu/Tails or any other linux USB on 2nd USB create encrypted container* transfer bitcoin wallet address generator to 2nd USB and run it from Live USB create Bitcoin addresses and save them on 2nd USB (optional but highly recommended) encrypt your private keys with strong password. **important** create many back up copies *cross platform encrypted container is hard to find since TrueCrypt (the only cross platform container that I know of) is no longer in development. Edit: as an added layer of security, use a spare computer that will never go online to generate Bitcoin addresses |
